  Ik kan helpen, maar eerst: wat bedoel je precies met "doesnt work"? Krijg je een foutmelding, komt er altijd false terug, of werkt het maar worden de wijzigingen niet opgeslagen? Geef zo mogelijk exceptiontekst of welke return (false, ...) je krijgt.

  Ondertussen een aantal veelvoorkomende oorzaken en verbeteringen — en een verbeterde versie van je methode:

  Mogelijke problemen
  - selectedMaterialId bevat geen geldige waarde (FindAsync geeft dan null).
  - Parse-fouten door verkeerde cultuur (decimal/comma vs dot). Dit geldt vooral voor prijs; in NL gebruiken gebruikers vaak komma.
  - Price/Quantity input bevat niet-getallen of lege tekst.
  - Type mismatches: gebruik liever decimal voor prijzen i.p.v. float.
  - FindAsync kan mislukken als de key-waarde niet het juiste type is.
  - Opslaan faalt door DB-fouten (concurrency, constraints) — kijk in de catch voor de echte exception.

  Verbeterde, robuustere implementatie (met cultuur-aware parsing en decimal voor prijs):

  using System.Globalization;
  using Microsoft.EntityFrameworkCore;
  using System.Diagnostics;

  private async Task<(bool Success, string? Error)> SaveMaterialAsync(bool allowFullEdit = false)
  {
      var fullEdit = allowFullEdit && CurrentUser.IsInkoop;

      var qtyText = QuantityInput.Text?.Trim();
      if (!int.TryParse(qtyText, NumberStyles.Integer, CultureInfo.CurrentCulture, out var newQuantity))
      {
          return (false, "Ongeldige hoeveelheid (voer een geheel getal in).");
      }

      var priceText = PriceInput.Text?.Trim();
      decimal? newPrice = null;
      if (fullEdit)
      {
          if (string.IsNullOrWhiteSpace(priceText) || !decimal.TryParse(priceText, NumberStyles.Number, CultureInfo.CurrentCulture, out var parsedPrice))
          {
              return (false, "Ongeldige prijs (voer een getal in).");
          }
          newPrice = parsedPrice;
      }

      if (selectedMaterialId == default)
      {
          return (false, "Ongeldig item geselecteerd.");
      }

      try
      {
          using var ctx = new AppDataContext();
          // gebruik FirstOrDefaultAsync om type/key-issues te vermijden als nodig
          var material = await ctx.Materials.FirstOrDefaultAsync(m => m.Id == selectedMaterialId);
          if (material == null)
          {
              return (false, "Item niet gevonden.");
          }

          if (!CurrentUser.IsInkoop && newQuantity > material.Quantity)
          {
              return (false, "Je mag de hoeveelheid niet verhogen.");
          }

          if (fullEdit)
          {
              material.Name = string.IsNullOrWhiteSpace(NameInput.Text) ? material.Name : NameInput.Text.Trim();
              material.Price = newPrice!.Value;
          }

          material.Quantity = newQuantity;

          await ctx.SaveChangesAsync();
          return (true, null);
      }
      catch (DbUpdateException dbEx)
      {
          Debug.WriteLine($"DB save error: {dbEx}");
          return (false, "Kon niet opslaan naar database. Probeer opnieuw.");
      }
      catch (Exception ex)
      {
          Debug.WriteLine($"Save error: {ex}");
          return (false, "Kon niet opslaan. Probeer opnieuw.");
      }
  }

  Aanvullende tips
  - Zet breakpoints of Debug.WriteLine voordat je SaveChangesAsync aanroept om te controleren welke waarden er op dat moment in material zitten.
  - Log de exception.Message en exception.StackTrace als je in de catch meer info wilt zien.
  - Als gebruikers zowel "1,23" als "1.23" kunnen invoeren, kun je eerst proberen parse met CurrentCulture en fallback naar InvariantCulture.
  - Gebruik decimal voor prijzen (precisie) i.p.v. float.

  Als je mij de concrete foutmelding of het gedrag geeft (wat er precies gebeurt), dan pas ik de oplossing gericht aan.

  Your code is almost correct, but when creating the `newAppointment`, you're still using `datePicker.Date.Value.DateTime` separately. Ensure you use the `combinedDateTime` for accurate date and time. Here’s the adjustment:

  ### Corrected Code Sample

  ```csharp
  private void OnSubmit(object sender, RoutedEventArgs e)
  {
      var selectedDate = datePicker.Date;
      var selectedTime = timePicker.Time;

      if (selectedDate != null)
      {
          // Convert DateTimeOffset to DateTime and add TimeSpan
          DateTime combinedDateTime = selectedDate.Value.Date.Add(selectedTime);

          // Use combinedDateTime
          var newAppointment = new Data.Models.Appointment(
              selectedDoctor.Id,
              selectedPatient.Id,
              title.Text,
              description.Text,
              combinedDateTime
          );

          // Proceed with creating the appointment
      }
      else
      {
          // Handle the case where no date is selected
      }
  }
  ```

  ### Key Points

  - **Combine Date and Time:**
    - Ensure `combinedDateTime` is used to pass both the date and time information when creating `newAppointment`.

  - **Null Checks:**
    - Verify `selectedDate` is not null before proceeding.

  This ensures your appointment captures both date and time correctly.

  Dank — dat helpt. "It stayes gray" kan meerdere dingen betekenen (de hele pagina grijs, knop blijft hangen, file picker blijft open, navigatie werkt niet). Geef even: wanneer precies gebeurt het (na openen van de pagina? na op "Save"? na kiezen van een afbeelding?), en zie je uitzonderingen in Output/Debug?

  Ondertussen de belangrijkste problemen en directe fixes in je code:

  1) Je gebruikt twee verschillende save-routes
  - Je hebt een bestaande (sync) SaveItem_Click die direct naar de DB schrijft en vervolgens navigeert.
  - Je hebt een nieuwe async SaveMaterialAsync die je momenteel niet gebruikt.
  Gebruik één consistente async flow en await alles — anders kun je UI-blocking, race-conditions of onverwachte states krijgen.

  2) Blokkerende IO op de UI-thread
  - File.ReadAllBytes(file.Path) is sync en kan de UI blokkeren als het groot is of als er beperkingen zijn. Gebruik async API's van StorageFile.
  - ctx.SaveChanges() is sync; gebruik await ctx.SaveChangesAsync() in async handlers.

  3) Afbeelding laden in WinUI/WinRT
  - Het direct new BitmapImage(new Uri(file.Path)) werkt niet altijd in WinUI/WinRT. Gebruik StorageFile.OpenReadAsync en BitmapImage.SetSourceAsync of converteer naar een stream eerst.

  4) Parsing/cultuur en types
  - Gebruik decimal voor prijzen (niet float) en parse met CultureInfo.CurrentCulture. Geef gebruikers feedback i.p.v. crashen bij Parse.

  Concrete aanpassingen — voorbeeldcode (vervang je SaveItem_Click en PickImage_Click, en roep SaveMaterialAsync aan):

  - Vervang SaveItem_Click door een async handler die SaveMaterialAsync gebruikt:

  private async void SaveItem_Click(object sender, RoutedEventArgs e)
  {
      var result = await SaveMaterialAsync(allowFullEdit: true); // of false afhankelijk van rechten
      if (!result.Success)
      {
          // toon foutmelding, bijv. met een ContentDialog of debug
          Debug.WriteLine(result.Error);
          return;
      }

      Frame.Navigate(typeof(ItemsPage));
  }

  - Pas SaveMaterialAsync zo aan dat je ook price en image (indien van toepassing) opslaat en SaveChangesAsync gebruikt (je hebt al grotendeels goede code). Zorg dat je material.Price zet wanneer fullEdit true:

  if (fullEdit)
  {
      material.Name = string.IsNullOrWhiteSpace(NameInput.Text) ? material.Name : NameInput.Text.Trim();
      material.Price = (double)newPrice.Value; // of decimal als model dat ondersteunt
  }

  material.Quantity = newQuantity;
  if (_imageData != null)
  {
      material.Image = _imageData; // indien model Image byte[] heeft
  }

  await ctx.SaveChangesAsync();

  - Vervang PickImage_Click door een async, niet-blocking versie en gebruik SetSourceAsync:

  private async void PickImage_Click(object sender, RoutedEventArgs e)
  {
      var picker = new Windows.Storage.Pickers.FileOpenPicker();
      var hwnd = WinRT.Interop.WindowNative.GetWindowHandle(App.MainWindow);
      WinRT.Interop.InitializeWithWindow.Initialize(picker, hwnd);
      picker.FileTypeFilter.Add(".jpg");
      picker.FileTypeFilter.Add(".png");

      var file = await picker.PickSingleFileAsync();
      if (file == null) return;

      using (var stream = await file.OpenReadAsync())
      {
          // lees bytes asynchroon
          var size = (int)stream.Size;
          _imageData = new byte[size];
          var dataReader = new Windows.Storage.Streams.DataReader(stream);
          await dataReader.LoadAsync((uint)size);
          dataReader.ReadBytes(_imageData);

          // reset positie en zet source voor preview
          stream.Seek(0);
          var bitmap = new BitmapImage();
          await bitmap.SetSourceAsync(stream);
          ImagePreview.Source = bitmap;
          ImagePreview.Visibility = Visibility.Visible;
      }
  }

  Opmerkingen/aanvullende debugtips
  - Zet breakpoints in SaveItem_Click en in SaveMaterialAsync om te controleren welke paden worden uitgevoerd.
  - Kijk naar de Output/Debug-console voor first-chance exceptions die misschien de UI vergrendelen.
  - Controleer of OnNavigatedTo überhaupt wordt aangeroepen en selectedMaterialId correct wordt gezet.
  - Als de UI "grijs" blijft: waarschijnlijk staat er ergens een lange blocking operatie op de UI-thread (synchrone SaveChanges, File.ReadAllBytes) of een onopgevangen uitzondering bij navigatie. Maak alle IO async en log exceptions.

  Als je wilt, plak de XAML van de pagina of beschrijf precies wanneer het grijze scherm verschijnt (na klikken op knop X, direct bij openen, alleen bij pick image, etc.). Dan geef ik een concrete gefixeerde versie van jouw volledige pagina.

  Je hebt ToList() nu goed toegepast. Nog één ding: je roept ChangeAppointmentList() in de constructor terwijl er nog geen patiënt geselecteerd is. Daardoor zet je de afsprakenlijst meteen op leeg. Fix: roep ChangeAppointmentList alleen aan bij een geldige selectie (of koppel het aan SelectionChanged) en wijzig de null-tak zodat hij niets overschrijft.

  Minimale aanpassing:

  public CreateReportPage()
  {
      InitializeComponent();
      using (var db = new AppDbContext())
      {
          PatientList.ItemsSource = db.Patients.ToList();
          AppointmentList.ItemsSource = db.Appointments
              .Where(a => a.Date > DateTime.Now)
              .ToList();
      }

      // Update afspraken wanneer de patiëntselectie wijzigt
      PatientList.SelectionChanged += (_, __) => ChangeAppointmentList();

      // Alleen initialiseren als er al een selectie is
      if (PatientList.SelectedItem != null)
          ChangeAppointmentList();
  }

  private void ChangeAppointmentList()
  {
      var patient = PatientList.SelectedItem as Data.Models.Patient;
      if (patient == null)
          return; // laat huidige AppointmentList staan

      using (var db = new AppDbContext())
      {
          var items = db.Appointments
              .Where(a => a.Date > DateTime.Now && a.PatientId == patient.Id)
              .ToList();

          AppointmentList.ItemsSource = items;
      }
  }

  Zo blijft AppointmentList gevuld met alle toekomstige afspraken totdat er een patiënt is gekozen, en wordt daarna gefilterd per patiënt zonder AccessViolation.

  It should add all the users from the database with NO SQL

  Helder — je wilt alle gebruikers uit de database ophalen met Entity Framework Core (dus zonder raw SQL). Hieronder zie je een kort, compleet voorbeeld in C# met een AppDataContext, een User-entiteit en voorbeelden van het ophalen (sync en async). Daarnaast toon ik hoe je de DbContext registreert in ASP.NET Core (DI).

  1) Entiteit (User)
  ```csharp
  using System.ComponentModel.DataAnnotations;
  using System.ComponentModel.DataAnnotations.Schema;

  [Table("users")] // optioneel: als je tabelnaam anders is
  public class User
  {
      [Key]
      public int Id { get; set; }

      public string? Username { get; set; }
      public string? Email { get; set; }

      // voeg andere velden toe die in je DB-tabel staan
  }
  ```

  2) AppDataContext (DbContext)
  ```csharp
  using Microsoft.EntityFrameworkCore;

  public class AppDataContext : DbContext
  {
      public DbSet<User> Users { get; set; } = null!;

      protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
      {
          optionsBuilder.UseMySql(
              "server=localhost;port=3306;user=root;password=;database=WorkCompass;",
              ServerVersion.AutoDetect("server=localhost;port=3306;user=root;password=;database=WorkCompass;")
          );
      }

      // optioneel: extra mapping via Fluent API
      protected override void OnModelCreating(ModelBuilder modelBuilder)
      {
          modelBuilder.Entity<User>().ToTable("users"); // indien nodig
      }
  }
  ```

  3) Alle gebruikers ophalen (synchron of asynchron)

  Synchron:
  ```csharp
  using (var ctx = new AppDataContext())
  {
      List<User> users = ctx.Users.ToList();
      // gebruik users
  }
  ```

  Asynchron (aanbevolen in webapps):
  ```csharp
  using Microsoft.EntityFrameworkCore;

  using (var ctx = new AppDataContext())
  {
      List<User> users = await ctx.Users.ToListAsync();
      // gebruik users
  }
  ```

  4) Voorbeeld in een ASP.NET Core controller (met DI)
  - Registreer DbContext in Program.cs / Startup.cs:
  ```csharp
  services.AddDbContext<AppDataContext>(options =>
      options.UseMySql("server=localhost;port=3306;user=root;password=;database=WorkCompass;",
                       ServerVersion.AutoDetect("server=localhost;port=3306;user=root;password=;database=WorkCompass;"))
  );
  ```
  - Gebruik in controller:
  ```csharp
  [ApiController]
  [Route("api/[controller]")]
  public class UsersController : ControllerBase
  {
      private readonly AppDataContext _ctx;

      public UsersController(AppDataContext ctx)
      {
          _ctx = ctx;
      }

      [HttpGet]
      public async Task<IActionResult> GetAll()
      {
          var users = await _ctx.Users.ToListAsync();
          return Ok(users);
      }
  }
  ```

  5) Belangrijke aandachtspunten
  - Zorg dat je de juiste EF Core MySQL provider hebt toegevoegd, bv. Pomelo.EntityFrameworkCore.MySql.
  - Zorg dat de properties van User overeenkomen met kolomnamen en types in de DB (of map ze met attributen/Fluent API).
  - Gebruik ToListAsync() in webapps om thread-blocking te voorkomen.
  - Als je relaties hebt, gebruik Include() om gerelateerde data mee te laden.

  Als je wil, kan ik:
  - jouw User-class genereren op basis van de huidige tabelkolommen (geef kolomnamen/types),
  - of de concrete code aanpassen naar jouw projectstructuur (console app, ASP.NET Core, etc.). Welke wil je verder?

  Hier een compacte, werkende vervanging voor je SaveMaterialAsync die in jouw bestand past zonder de rest van de code te veranderen. Belangrijkste fixes:
  - Prijs wordt correct geparsed naar float (met fallback voor verschillende decimal separators).
  - material.Price wordt daadwerkelijk gezet bij fullEdit.
  - Async EF SaveChangesAsync wordt gebruikt en exceptions gelogd.

  Plak deze methode ter vervanging van de bestaande SaveMaterialAsync:

  private async Task<(bool Success, string? Error)> SaveMaterialAsync(bool allowFullEdit = false)
  {
      var fullEdit = allowFullEdit && CurrentUser.IsInkoop;

      var qtyText = QuantityInput.Text?.Trim();
      if (!int.TryParse(qtyText, NumberStyles.Integer, CultureInfo.CurrentCulture, out var newQuantity))
      {
          return (false, "Ongeldige hoeveelheid (voer een geheel getal in).");
      }

      float? newPrice = null;
      var priceText = PriceInput.Text?.Trim();
      if (fullEdit)
      {
          if (string.IsNullOrWhiteSpace(priceText))
              return (false, "Ongeldige prijs (voer een getal in).");

          if (!float.TryParse(priceText, NumberStyles.Float | NumberStyles.AllowThousands, CultureInfo.CurrentCulture, out var parsedFloat))
          {
              // fallback: probeer invariant culture (voor '.' als decimale scheiding)
              if (!float.TryParse(priceText, NumberStyles.Float | NumberStyles.AllowThousands, CultureInfo.InvariantCulture, out parsedFloat))
              {
                  return (false, "Ongeldige prijs (voer een getal in).");
              }
          }
          newPrice = parsedFloat;
      }

      if (selectedMaterialId == default)
      {
          return (false, "Ongeldig item geselecteerd.");
      }

      try
      {
          using var ctx = new AppDataContext();
          var material = await ctx.Materials.FirstOrDefaultAsync(m => m.Id == selectedMaterialId);
          if (material == null)
          {
              return (false, "Item niet gevonden.");
          }

          if (!CurrentUser.IsInkoop && newQuantity > material.Quantity)
          {
              return (false, "Je mag de hoeveelheid niet verhogen.");
          }

          if (fullEdit)
          {
              material.Name = string.IsNullOrWhiteSpace(NameInput.Text) ? material.Name : NameInput.Text.Trim();
              if (newPrice.HasValue)
                  material.Price = newPrice.Value;
          }

          material.Quantity = newQuantity;

          await ctx.SaveChangesAsync();
          return (true, null);
      }
      catch (DbUpdateException dbEx)
      {
          Debug.WriteLine($"DB save error: {dbEx}");
          return (false, "Kon niet opslaan naar database. Probeer opnieuw.");
      }
      catch (Exception ex)
      {
          Debug.WriteLine($"Save error: {ex}");
          return (false, "Kon niet opslaan. Probeer opnieuw.");
      }
  }

  Als je na deze wijziging nog steeds een "grijs" of geblokkeerd scherm krijgt, laat weten wanneer dat gebeurt (bij openen pagina, bij Save, bij image pick). Dan kijk ik welke sync-call in de UI-thread nog voor problemen zorgt (bijv. File.ReadAllBytes of ctx.SaveChanges ergens anders).

  Hier een compact, kant-en-klaar voorbeeld in C# dat alle gebruikers ophaalt met Entity Framework Core (geen raw SQL). Ik geef: 1) User-entiteit, 2) AppDataContext (zoals jouw OnConfiguring), 3) Console-app voorbeeld (async), en 4) korte aanwijzingen voor ASP.NET Core DI. Vergeet niet de NuGet-pakketten te installeren.

  Benodigde NuGet-pakketten:
  - Pomelo.EntityFrameworkCore.MySql
  - Microsoft.EntityFrameworkCore.Tools (optioneel voor migrations)

  Installeren:
  dotnet add package Pomelo.EntityFrameworkCore.MySql
  dotnet add package Microsoft.EntityFrameworkCore.Tools

  1) User-entiteit (C#)
  ```csharp
  using System.ComponentModel.DataAnnotations;
  using System.ComponentModel.DataAnnotations.Schema;

  [Table("users")] // pas aan naar je echte tabelnaam indien nodig
  public class User
  {
      [Key]
      public int Id { get; set; }

      public string? Username { get; set; }
      public string? Email { get; set; }

      // Voeg hier extra velden toe die in je DB-tabel staan
  }
  ```

  2) AppDataContext (DbContext)
  ```csharp
  using Microsoft.EntityFrameworkCore;

  public class AppDataContext : DbContext
  {
      public DbSet<User> Users { get; set; } = null!;

      protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
      {
          optionsBuilder.UseMySql(
              "server=localhost;port=3306;user=root;password=;database=WorkCompass;",
              ServerVersion.AutoDetect("server=localhost;port=3306;user=root;password=;database=WorkCompass;")

      {
          modelBuilder.Entity<User>().ToTable("users"); // optioneel, alleen als nodig
      }
  }
  ```

  3) Console-app: alle users ophalen (async aanbevolen)
  ```csharp
  using System;
  using System.Threading.Tasks;
  using Microsoft.EntityFrameworkCore;
  using System.Linq;

  class Program
  {
      static async Task Main(string[] args)
      {
          using var ctx = new AppDataContext();

          // Asynchroon alle users ophalen
          var users = await ctx.Users.ToListAsync();

          foreach (var u in users)
          {
              Console.WriteLine($"Id: {u.Id}, Username: {u.Username}, Email: {u.Email}");
          }
      }
  }
  ```

  Als je synchron wilt (niet aanbevolen in servers/webapps):
  ```csharp
  using (var ctx = new AppDataContext())
  {
      var users = ctx.Users.ToList();
      // ...
  }
  ```

  4) ASP.NET Core (DI) korte instructie
  - In Program.cs / Startup.cs registreren:
  ```csharp
  services.AddDbContext<AppDataContext>(options =>
      options.UseMySql(
          "server=localhost;port=3306;user=root;password=;database=WorkCompass;",
          ServerVersion.AutoDetect("server=localhost;port=3306;user=root;password=;database=WorkCompass;")
      )
  );
  ```
  - Controller voorbeeld:
  ```csharp
  [ApiController]
  [Route("api/[controller]")]
  public class UsersController : ControllerBase
  {
      private readonly AppDataContext _ctx;
      public UsersController(AppDataContext ctx) => _ctx = ctx;

      [HttpGet]
      public async Task<IActionResult> GetAll()
      {
          var users = await _ctx.Users.ToListAsync();
          return Ok(users);
      }
  }
  ```

  Opmerkingen / tips
  - Controleer dat kolomnamen/types in DB overeenkomen met properties, of map via attributen/Fluent API.
  - Gebruik ToListAsync() in webapps om blocking te vermijden.
  - Gebruik veilige wachtwoordopslag (nu staat het wachtwoord leeg in de connection string — productiesystemen: veilige secret management).
  - Als je relaties wilt includen, gebruik Include(u => u.Relation).

  Wil je dat ik dit aanpas aan jouw bestaande projectbestanden (bijv. namespace, exacte kolomnamen), plak dan even je huidige User-tabel schema of je projectstructuur.

  Top! Je hebt alles al bijna klaar. We voegen nu een inschrijf/uitschrijf-flow toe die:

  - Auth vereist (ingelogde gebruikers)
  - Capaciteit bewaakt (met concurrency lock)
  - Dubbele inschrijvingen voorkomt (DB-unique index)
  - Eventueel overlapping met andere workshops checkt (optioneel blok)

  Hieronder alle stappen + complete code per bestand.

  Stappenplan
  1) Routes toevoegen:
  - POST /workshops/{workshop}/enroll -> inschrijven (alleen ingelogd)
  - DELETE /workshops/{workshop}/enroll -> uitschrijven (alleen ingelogd)
  - Optioneel: gebruik named routes in de Blade.

  2) Controller maken:
  - EnrollmentController met store en destroy
  - In store: transaction + lockForUpdate op workshop, capaciteit check, overlap-check (optioneel), unique-inschrijving
  - In destroy: eigen inschrijving verwijderen

  3) Blade show aanpassen:
  - Vervang de <a> naar een formulier met POST/DELETE en @csrf
  - Toon knoppen “Schrijf je in” of “Uitschrijven” afhankelijk van status
  - Toon flash messages

  4) Database constraint:
  - Unique index op enrollments: (user_id, workshop_id)
  - Als je de tabel nog niet had: maak de hele create-migration
  - Als je hem wel had: alleen een migration om de unique index toe te voegen

  5) (Kleine bugfix) In WorkshopController@index sorteren op start_at i.p.v. start_time

  6) Migrate + testen:
  - php artisan migrate
  - In UI: open workshop detail, klik “Schrijf je in”, controleer capaciteit en dubbele inschrijving

      {
          Schema::table('enrollments', function (Blueprint $table) {
              // Zorg dat de kolommen bestaan; anders eerst create-table migration maken.
              if (!Schema::hasColumn('enrollments', 'user_id') || !Schema::hasColumn('enrollments', 'workshop_id')) {
                  return;
              }

              // Voeg unieke index toe om dubbele inschrijvingen te voorkomen
              $table->unique(['user_id', 'workshop_id'], 'enrollments_user_workshop_unique');

              $table->dropUnique('enrollments_user_workshop_unique');
          });
      }
  };


  Optioneel: als je de enrollments-tabel nog niet had, gebruik dan deze create-migration in plaats van de add-unique:

  C:\Users\EXTTICT032\Herd\TopTone\database\migrations\2026_04_14_000000_create_enrollments_table.php
  <?php

  use Illuminate\Database\Migrations\Migration;
  use Illuminate\Database\Schema\Blueprint;
  use Illuminate\Support\Facades\Schema;

  return new class extends Migration {
      public function up(): void
      {
          Schema::create('enrollments', function (Blueprint $table) {
              $table->id();
              $table->foreignId('workshop_id')->constrained()->cascadeOnDelete();
              $table->foreignId('user_id')->constrained()->cascadeOnDelete();
              $table->string('status')->default('confirmed'); // Pas aan aan jouw EnrollmentStatus values
              $table->timestamps();

              $table->unique(['user_id', 'workshop_id'], 'enrollments_user_workshop_unique');
          });
      }

      public function down(): void
      {
          Schema::dropIfExists('enrollments');
      }
  };


  Kleine fix in je index (start_at i.p.v. start_time)

  C:\Users\EXTTICT032\Herd\TopTone\app\Http\Controllers\WorkshopController.php
  // ... in index()
  public function index()
  {
      $workshops = Workshop::with(['instructors', 'enrollments', 'room'])
          ->orderBy('start_at', 'asc') // was start_time
          ->get();

      return view('workshops.index', [
          'workshops' => $workshops,
      ]);
  }


  Wat jij moet doen
  1) Bestanden toevoegen/wijzigen zoals hierboven (EnrollmentController, routes, Blade, migrations).
  2) Composer dump-autoload (optioneel): composer dump-autoload
  3) Database migreren:
  - Als je de tabel al hebt: alleen de add-unique migration laten draaien.
  - Als je de tabel nog niet hebt: eerst de create_enrollments_table migration.
  - php artisan migrate
  4) Testen:
  - Ga naar /workshops, kies een workshop
  - Klik “Schrijf je in” (ingelogd zijn)
  - Klik daarna “Uitschrijven” om te testen
  - Probeer twee keer snel te klikken: je krijgt geen dubbele records en capaciteit blijft kloppen
  5) Status enum check:
  - Als jouw App\Enums\EnrollmentStatus andere cases heeft dan ‘confirmed’, pas de regel in EnrollmentController aan (of laat status weg als je DB-kolom een default heeft).

  Wil je ook een “Mijn inschrijvingen”-overzicht of een admin-lijst met deelnemers? Zeg het even; dan voeg ik routes, controller en Blade toe.

  Om ervoor te zorgen dat de `PatientClassification` correct wordt gekoppeld bij het maken van een nieuwe patiënt, moeten we enkele aanpassingen doen aan de `Save_Click`-methode. Momenteel worden de classificaties toegevoegd als een lijst van strings, maar we moeten ze koppelen aan hun respectievelijke `PatientClassification`-objecten.

  ### Stap 1: Aanpassen `Save_Click`-methode

  1. **Verander de manier waarop de classificaties worden opgeslagen:**

     We willen in plaats van een lijst van strings, een lijst van `PatientClassification` objecten aanmaken en deze correct koppelen aan het nieuwe patiëntobject. 

  2. **Voeg de geselecteerde classificaties toe aan de database:**

     Voeg de nieuwe `PatientClassification`-records toe aan de database voordat je `context.SaveChanges()` aanroept om ervoor te zorgen dat ze gekoppeld zijn aan de nieuw aangemaakte patiënt.

  ```csharp
  private void Save_Click(object sender, RoutedEventArgs e)
  {
      ErrorText.Visibility = Visibility.Collapsed;

      if (string.IsNullOrWhiteSpace(FirstNameInput.Text) || string.IsNullOrWhiteSpace(LastNameInput.Text))
      {
          ErrorText.Text = "Please fill in all required fields (First Name and Last Name).";
          ErrorText.Visibility = Visibility.Visible;
          return;
      }

      using var context = new AppDbContext();

      var selectedDoctor = DoctorComboBox.SelectedItem as User;
      var doctorUsername = selectedDoctor?.Username ?? "Geen voorkeur";

      var doctor = context.Users.FirstOrDefault(u => u.Username == doctorUsername);

      if (doctor == null && doctorUsername != "Geen voorkeur")
      {
          ErrorText.Text = "Geselecteerde dokter niet gevonden.";
          ErrorText.Visibility = Visibility.Visible;
          return;
      }

      // Haal de geselecteerde classificaties op en maak er `PatientClassification` objecten van
      var selectedClassifications = ClassificationsListBox.Items
          .Cast<ListBoxItem>()
          .Select(item => item.Content as CheckBox)
          .Where(checkBox => checkBox.IsChecked == true)
          .Select(checkBox => new PatientClassification
          {
              Classification = checkBox.Content.ToString()
          })
          .ToList();

      var newPatient = new CareTracker.Data.Patient
      {
          FirstName = FirstNameInput.Text,
          LastName = LastNameInput.Text,
          BirthDate = BirthDateInput.Date.DateTime,
          Address = AddressInput.Text ?? "",
          PhoneNumber = PhoneNumberInput.Text ?? "",
          Email = EmailInput.Text ?? "",
          DoctorId = doctor?.Id ?? 0, // Gebruik 0 als er geen voorkeursdokter is
          PatientClassifications = selectedClassifications // Gebruik de `PatientClassification` objecten
      };

      if (doctor != null || doctorUsername == "Geen voorkeur")
      {
          context.Patients.Add(newPatient);
          context.SaveChanges();

          // Voer de navigatie alleen uit als het opslaan gelukt is
          NavigateBack();
      }
      else
      {
          ErrorText.Text = "Selecteer een dokter.";
          ErrorText.Visibility = Visibility.Visible;
      }
  }
  ```

  ### Stap 2: Verifieer de Databaseconfiguratie

  Zorg ervoor dat in `AppDbContext`, de relatie tussen `Patient` en `PatientClassification` correct is gedefinieerd. Het moet een één-op-veel-relatie zijn.

  ```csharp
  protected override void OnModelCreating(ModelBuilder modelBuilder)
  {
      modelBuilder.Entity<Patient>()
          .HasMany(p => p.PatientClassifications)
          .WithOne(pc => pc.Patient)
          .HasForeignKey(pc => pc.PatientId);

      // Rest van de configuraties...
  }
  ```

  ### Samenvatting

  Met deze wijzigingen worden de classificaties toegevoegd als gekoppelde records in de tabel `PatientClassification`, gekoppeld aan de nieuw aangemaakte patiënt. Zorg dat je de context en UI-elementen correct instelt en controleer of de verbinding met de database goed werkt.

  Hier een kant-en-klaar enkel-bestand (Program.cs) dat alles bevat: de User-entiteit, de AppDataContext in de Data-namespace en een async Main die alle users ophaalt en print. Plaats dit bestand in je project (bijv. root) en voer uit. Zorg dat je de juiste NuGet-pakketten installeert (onderaan kort aangegeven).

  Program.cs
  ```csharp
  using System;
  using System.Collections.Generic;
  using System.ComponentModel.DataAnnotations;
  using System.ComponentModel.DataAnnotations.Schema;
  using System.Threading.Tasks;
  using Microsoft.EntityFrameworkCore;

  namespace Data
  {
      // Entiteit: User - pas properties aan naar jouw tabelkolommen
      [Table("users")] // wijzig indien jouw tabel een andere naam heeft
      public class User
      {
          [Key]
          public int Id { get; set; }

          public string? Username { get; set; }
          public string? Email { get; set; }

          // Voeg hier overige kolommen toe
      }

      // DbContext: AppDataContext
      public class AppDataContext : DbContext
      {
          public DbSet<User> Users { get; set; } = null!;

          protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
          {
              optionsBuilder.UseMySql(
                  "server=localhost;port=3306;user=root;password=;database=WorkCompass;",
                  ServerVersion.AutoDetect("server=localhost;port=3306;user=root;password=;database=WorkCompass;")
              );
          }

          protected override void OnModelCreating(ModelBuilder modelBuilder)
          {
              modelBuilder.Entity<User>().ToTable("users"); // optioneel
          }
      }
  }

  class Program
  {
      static async Task Main(string[] args)
      {
          try
          {
              using var ctx = new Data.AppDataContext();

              // Asynchroon alle users ophalen
              List<Data.User> users = await ctx.Users.ToListAsync();

              if (users.Count == 0)
              {
                  Console.WriteLine("Geen users gevonden.");
              }
              else
              {
                  foreach (var u in users)
                  {
                      Console.WriteLine($"Id: {u.Id}, Username: {u.Username}, Email: {u.Email}");
                  }
              }
          }
          catch (Exception ex)
          {
              Console.WriteLine("Fout bij ophalen users: " + ex.Message);
          }
      }
  }
  ```

  NuGet-pakketten (vereist)
  - Pomelo.EntityFrameworkCore.MySql
  - Microsoft.EntityFrameworkCore (meestal transitief via Pomelo)
  Installatie (voorbeeld):
  dotnet add package Pomelo.EntityFrameworkCore.MySql

  Opmerkingen
  - Pas de User-properties en de tabelnaam aan als jouw database andere kolomnamen heeft.
  - In productie: bewaar connection strings veilig (User Secrets / environment variables / Azure Key Vault).
  - Gebruik ToListAsync() (zoals hierboven) voor niet-blocking I/O in apps/servers.

  Wil je dat ik het bestand aanpas naar jouw exacte kolomnamen of dat ik een ASP.NET Core controller-voorbeeld maak met DI?

  Ziet er bijna goed uit. Twee kleine puntjes voor AppointmentList:

  - Laat AppointmentList staan wanneer er (nog) geen patiënt is geselecteerd. Je zet ’m nu leeg bij patient == null, waardoor je initiële “alle toekomstige afspraken” direct overschreven kan worden.
  - Optioneel: selecteer de eerste patiënt na het vullen, zodat AppointmentList meteen gefilterd wordt.

  Aangepaste code (alleen AppointmentList-gerelateerd):

  public CreateReportPage()
  {
      InitializeComponent();
      using (var db = new AppDbContext())
      {
          PatientList.ItemsSource = db.Patients
              .AsNoTracking()
              .ToList();

          AppointmentList.ItemsSource = db.Appointments
              .Where(a => a.Date > DateTime.Now)
              .AsNoTracking()
              .ToList();
      }

      PatientList.SelectionChanged += (_, __) => ChangeAppointmentList();

      // Optioneel: automatisch eerste patiënt selecteren (triggert ChangeAppointmentList)
      if (PatientList.Items?.Count > 0)
          PatientList.SelectedIndex = 0;
  }

  private void ChangeAppointmentList()
  {
      if (PatientList.SelectedItem is not Data.Models.Patient patient)
          return; // laat huidige AppointmentList staan

      using var db = new AppDbContext();
      AppointmentList.ItemsSource = db.Appointments
          .Where(a => a.Date > DateTime.Now && a.PatientId == patient.Id)
          .AsNoTracking()
          .ToList();
  }

  Met deze aanpassing blijft de initiële lijst intact tot er een patiënt gekozen is, en daarna wordt netjes gefilterd per patiënt. De AccessViolation door uitgestelde enumeratie is hiermee ook opgelost.

  Sorry — helder nu. Je hebt een bestaande AppDataContext in de folder Data/AppDataContext en je wilt alleen de gebruikersnamen (UserName) ophalen. Hieronder een compact & werkend voorbeeld (Program.cs) dat ervan uitgaat dat jouw AppDataContext en User-entiteit in namespace Data zitten. Dit haalt alleen de UserName-kolom op (geen raw SQL), gebruikt AsNoTracking() voor performance en ToListAsync() voor async I/O.

  Program.cs
  ```csharp
  using System;
  using System.Threading.Tasks;
  using System.Linq;
  using Microsoft.EntityFrameworkCore;
  using Data; // jouw AppDataContext en User zitten in deze namespace

  class Program
  {
      static async Task Main(string[] args)
      {
          try
          {
              using var ctx = new AppDataContext();

              // Alleen de UserName-kolom ophalen (projectie naar string)
              var usernames = await ctx.Users
                                       .AsNoTracking()               // geen change tracking, sneller
                                       .Select(u => u.Username)      // alleen UserName ophalen
                                       .ToListAsync();

              if (usernames == null || usernames.Count == 0)
              {
                  Console.WriteLine("Geen gebruikers gevonden.");
              }
              else
              {
                  foreach (var name in usernames)
                  {
                      Console.WriteLine(name ?? "(null)");
                  }
              }
          }
          catch (Exception ex)
          {
              Console.WriteLine("Fout bij ophalen van usernames: " + ex.Message);
          }
      }
  }
  ```

  Belangrijke aandachtspunten
  - Zorg dat AppDataContext een DbSet<User> Users { get; set; } heeft en dat de User-class een property Username / UserName heeft.
  - Dit gebruikt LINQ-to-Entities, geen raw SQL.
  - Installeer de juiste NuGet-provider (bijv. Pomelo.EntityFrameworkCore.MySql) als je MySQL gebruikt.
  - Als je namespace of classnamen anders zijn, pas de using/typen aan.

  Wil je dat ik exact met jouw AppDataContext-bestand mee kijk (plak de bestanden/folders), zodat ik de exacte using en property-namen kan aanpassen?

  welke hier zorgt ervoor dat hij de loginpagina overslaat en gelijk naar de homepage gaat of is dat niet hierin

  Het gedrag dat je beschrijft, namelijk het overslaan van de loginpagina en direct naar de homepage gaan, lijkt niet expliciet in de code aanwezig. Het huidige fragment van de `LoginPage` behandelt gebruikersinvoer en authenticatie. Hier zijn een paar dingen om te controleren als je wilt dat een gebruiker automatisch wordt doorgestuurd:

  1. **Controleer Authenticatesessie bij Opstarten:**
     Controleer bij het laden van de applicatie of er al een actieve sessie is. Dit kan in de hoofdpagina van de applicatie, misschien `App.xaml.cs`, of in de `OnNavigatedTo`-methode van een eerste geladen pagina (zoals `MainPage`).

     ```csharp
     protected override void OnLaunched(LaunchActivatedEventArgs args)
     {
         if (UserSession.IsUserAuthenticated())
         {
             // Navigeren naar de homepage omdat de gebruiker is ingelogd
             rootFrame.Navigate(typeof(HomePage));
         }
         else
         {
             // Navigeren naar de loginpagina
             rootFrame.Navigate(typeof(LoginPage));
         }
     }
     ```

  2. **Controle op Session in `UserSession`:**
     Zorg ervoor dat je een check hebt, bijvoorbeeld `IsUserAuthenticated()`, die controleert of er al een sessie actief is.

     ```csharp
     public static bool IsUserAuthenticated()
     {
         // Implementeer logica om te bepalen of er een sessie bestaat
         return _currentUser != null; // If _currentUser is een variabele die de status van de sessie opslaat
     }
     ```

  3. **In `LoginPage` prioriteiten stellen:**
     Zorg dat `LoginPage` niet hoeft te worden geladen als een actieve sessie aanwezig is. Dit stukje kan in de pagina zelf of bij de applicatiestart worden toegevoegd.

  4. **Opgeruimde Logica:**
     Controleer `UserSession` voor methodes zoals `ClearSession()` en `SetSession(...)` om ervoor te zorgen dat ze correct authenticatie- en sessiebeheer uitvoeren.

  Als dat nog niet gebeurt, dien je de juiste logica toe te voegen in het gedeelte waar deze beslissingen worden genomen. Dat kan variëren afhankelijk van hoe de applicatie is gestructureerd buiten de `LoginPage`.

  dus dit was hem toch?

  Ja, dat klopt. Het fragment dat je aangeeft, is verantwoordelijk voor de navigatie naar de `HomePage` nadat de gebruiker succesvol is geauthenticeerd met hun e-mail en wachtwoord.

  Als je wilt dat de applicatie automatisch naar de `HomePage` gaat zonder dat de gebruiker de inloggegevens elke keer opnieuw hoeft in te voeren (bijvoorbeeld als ze al eerder zijn ingelogd), moet je er rekening mee houden dat je sessiemanagement buiten deze specifieke `LoginPage` plaatst.

  Je kunt een controlemechanisme gebruiken bij het starten van de applicatie (of bij het laden van een specifieke pagina) om te bepalen of de gebruiker al is ingelogd. Als dat zo is, navigeer dan direct naar de `HomePage`, anders blijf je op de `LoginPage`.

  Dus het huidige gedrag zoals beschreven in de code is voor het inloggen vanuit de `LoginPage`, maar om het overslaan ervan te implementeren moet je ervoor zorgen dat je sessiebeheer correct werkt bij het opstarten van de applicatie.

  Om ervoor te zorgen dat de `PatientClassifications` correct worden weergegeven en opgeslagen in de `PatientPage`, moeten we de volgende stappen ondernemen:

  1. **Data Binding Configureren:**
     Zorg ervoor dat de classificaties correct worden gebonden aan de `ListView` in `PatientDetailsPanel`.

  2. **Koppelingslogica Toevoegen:**
     Implementeer de logica om de `PatientClassifications` op te halen en weer te geven.

  ### Stap 1: Data Binding Configureren

  Pas de XAML aan zodat het de juiste gegevensbron voor de `ClassificationsListView` gebruikt.

  ```xml
  <ListView x:Name="ClassificationsListView" ItemsSource="{Binding PatientClassifications}" Visibility="Collapsed">
      <ListView.ItemTemplate>
          <DataTemplate>
              <TextBlock Text="{Binding Classification}" />
          </DataTemplate>
      </ListView.ItemTemplate>
  </ListView>
  ```

  ### Stap 2: Koppelingslogica Toevoegen en Lijst bijwerken

  Verander de `PatientListView_SelectionChanged`-methode om de classificaties correct weer te geven.

  ```csharp
  private void PatientListView_SelectionChanged(object sender, SelectionChangedEventArgs e)
  {
      var selectedPatient = PatientListView.SelectedItem as CareTracker.Data.Patient;

      if (selectedPatient != null)
      {
          System.Diagnostics.Debug.WriteLine($"Selected Patient: {selectedPatient.FirstName} {selectedPatient.LastName}");

          if (selectedPatient.Doctor != null)
          {
              System.Diagnostics.Debug.WriteLine($"Dokter: {selectedPatient.Doctor.Name}");
              DoctorLabel.Visibility = Visibility.Visible;
              DoctorNameTextBlock.Visibility = Visibility.Visible;
          }
          else
          {
              DoctorLabel.Visibility = Visibility.Collapsed;
              DoctorNameTextBlock.Visibility = Visibility.Collapsed;
          }

          // Stel de DataContext in
          PatientDetailsPanel.DataContext = selectedPatient;

          // Controleer classificaties via PatientClassifications
          bool hasClassifications = selectedPatient.PatientClassifications.Any();
          ClassificationsLabel.Visibility = hasClassifications ? Visibility.Visible : Visibility.Collapsed;
          ClassificationsListView.Visibility = hasClassifications ? Visibility.Visible : Visibility.Collapsed;
      }
      else
      {
          DoctorLabel.Visibility = Visibility.Collapsed;
          DoctorNameTextBlock.Visibility = Visibility.Collapsed;
          ClassificationsLabel.Visibility = Visibility.Collapsed;
          ClassificationsListView.Visibility = Visibility.Collapsed;
      }

      bool isPatientSelected = selectedPatient != null;
      DeleteButton.Visibility = isPatientSelected ? Visibility.Visible : Visibility.Collapsed;
      ReportsButton.Visibility = isPatientSelected ? Visibility.Visible : Visibility.Collapsed;
  }
  ```

  ### Controleren en Testen

  1. **Databasecontrole:**
     Zorg ervoor dat de `PatientClassification`-records correct worden gevuld in de database.

  2. **UI-test:**
     Controleer of de classificaties correct worden weergegeven in de gebruikersinterface wanneer een patiënt wordt geselecteerd.

  Met deze wijzigingen worden de `PatientClassifications` correct weergegeven in de `PatientPage` en blijven ze consistent met de gegevens opgeslagen in de database.

          }
      }
  }

  Kun je de functie fixen zodat de normale gebruiker geen gebruiker met een inkoop roll de amount van de quantity omlaag haalt en de Inkoop de amount omhoog mag doen maar niet omlaag en niemand mag de prijs veranderen alleen de beheerder (dus je moet kijken naar de users en welke rollen ze hebben)

  Ik heb de `SaveMaterialAsync`-functie aangepast zodat de toegangsregels op rollen werken zoals je vroeg:

  - Inkoop: mag alleen de hoeveelheid verhogen (of gelijk houden), niet verlagen.
  - Normale gebruiker: mag alleen de hoeveelheid verlagen (of gelijk houden), niet verhogen.
  - Beheerder (admin): mag alles, inclusief prijswijzigingen.
  - Alleen beheerder mag de prijs aanpassen; als een niet-beheerder probeert de prijs te wijzigen wordt dat geweigerd.

  Let op: ik ga uit van twee properties op je CurrentUser: `IsInkoop` en `IsBeheerder`. Als jouw user/role-model anders heet, moet je dat aanpassen.

  Vervang je huidige `SaveMaterialAsync` door de volgende implementatie:

  private async Task<(bool Success, string? Error)> SaveMaterialAsync(bool allowFullEdit = false)
  {
      var fullEdit = allowFullEdit && CurrentUser.IsBeheerder;

      var qtyText = QuantityInput.Text?.Trim();
      if (!int.TryParse(qtyText, NumberStyles.Integer, CultureInfo.CurrentCulture, out var newQuantity))
      {
          return (false, "Ongeldige hoeveelheid (voer een geheel getal in).");
      }

      var priceText = PriceInput.Text?.Trim();
      float? newPrice = null;
      if (!string.IsNullOrWhiteSpace(priceText))
      {
          // Probeer prijs te parsen als er iets is ingevuld
          if (!float.TryParse(priceText, NumberStyles.Number, CultureInfo.CurrentCulture, out var parsedPrice))
          {
              return (false, "Ongeldige prijs (voer een getal in).");
          }
          newPrice = parsedPrice;
      }

      if (selectedMaterialId == default)
      {
          return (false, "Ongeldig item geselecteerd.");
      }

      try
      {
          using var ctx = new AppDataContext();
          var material = await ctx.Materials.FirstOrDefaultAsync(m => m.Id == selectedMaterialId);
          if (material == null)
          {
              return (false, "Item niet gevonden.");
          }

          // Prijsbeleid: alleen beheerder mag prijs wijzigen.
          if (newPrice.HasValue && !CurrentUser.IsBeheerder)
          {
              // Als niet-beheerder iets anders invult dan huidige prijs -> weigeren
              if (Math.Abs(material.Price - newPrice.Value) > 0.0001f)
              {
                  return (false, "Alleen beheerder mag de prijs aanpassen.");
              }
              // als nieuw ingevoerde prijs gelijk is aan bestaande prijs -> negeren
              newPrice = null;
          }

          // Hoeveelheidsbeleid op basis van rol
          if (CurrentUser.IsBeheerder)
          {
              // beheerder mag alles
          }
          else if (CurrentUser.IsInkoop)
          {
              // Inkoop mag alleen verhogen of gelijk houden
              if (newQuantity < material.Quantity)
              {
                  return (false, "Als Inkoop mag je de hoeveelheid niet verlagen.");
              }
          }
          else
          {
              // normale gebruiker mag alleen verlagen of gelijk houden
              if (newQuantity > material.Quantity)
              {
                  return (false, "Als gebruiker mag je de hoeveelheid niet verhogen.");
              }
          }

          // Naamwijziging: alleen toestaan voor beheerder als fullEdit gevraagd is
          if (fullEdit)
          {
              material.Name = string.IsNullOrWhiteSpace(NameInput.Text) ? material.Name : NameInput.Text.Trim();
          }

          // Pas hoeveelheid en eventueel prijs aan
          material.Quantity = newQuantity;
          if (newPrice.HasValue && CurrentUser.IsBeheerder)
          {
              material.Price = newPrice.Value;
          }

          await ctx.SaveChangesAsync();
          return (true, null);
      }
      catch (DbUpdateException dbEx)
      {
          Debug.WriteLine($"DB save error: {dbEx}");
          return (false, "Kon niet opslaan naar database. Probeer opnieuw.");
      }
      catch (Exception ex)
      {
          Debug.WriteLine($"Save error: {ex}");
          return (false, "Kon niet opslaan. Probeer opnieuw.");
      }
  }

  Kort nog dit:
  - Als jouw CurrentUser-API andere property-namen gebruikt (bijv. Role == "Inkoop"/"Beheerder"), vervang `CurrentUser.IsInkoop` / `CurrentUser.IsBeheerder` door jouw checks.
  - Ik ga ervan uit dat `material.Price` type float is (zoals in je andere code). Als dat anders is (decimal), pas de types/parsing aan.
  - Als je wil dat ook naamwijziging door anderen toegestaan is, of dat fullEdit-logica anders moet werken, geef even aan hoe je dat wilt en dan pas ik het aan.

  Mijn excuses voor de verwarring. Laten we de functie aanpassen en een paar verbeteringen doorvoeren:

  ### Stap 1: Pas de `PatientListView_SelectionChanged` Functie aan

  ```csharp
  private void PatientListView_SelectionChanged(object sender, SelectionChangedEventArgs e)
  {
      var selectedPatient = PatientListView.SelectedItem as CareTracker.Data.Patient;

      if (selectedPatient != null)
      {
          System.Diagnostics.Debug.WriteLine($"Selected Patient: {selectedPatient.FirstName} {selectedPatient.LastName}");

          if (selectedPatient.Doctor != null)
          {
              System.Diagnostics.Debug.WriteLine($"Dokter: {selectedPatient.Doctor.Name}");
              DoctorLabel.Visibility = Visibility.Visible;
              DoctorNameTextBlock.Visibility = Visibility.Visible;
          }
          else
          {
              DoctorLabel.Visibility = Visibility.Collapsed;
              DoctorNameTextBlock.Visibility = Visibility.Collapsed;
          }

          // Stel de DataContext in
          PatientDetailsPanel.DataContext = selectedPatient;

          // Controleer en toon classificaties
          ClassificationsListView.ItemsSource = selectedPatient.PatientClassifications.Select(pc => pc.Classification).ToList();
          ClassificationsListView.Visibility = selectedPatient.PatientClassifications.Any() ? Visibility.Visible : Visibility.Collapsed;
      }
      else
      {
          DoctorLabel.Visibility = Visibility.Collapsed;
          DoctorNameTextBlock.Visibility = Visibility.Collapsed;
          ClassificationsListView.Visibility = Visibility.Collapsed;
      }

      bool isPatientSelected = selectedPatient != null;
      DeleteButton.Visibility = isPatientSelected ? Visibility.Visible : Visibility.Collapsed;
      ReportsButton.Visibility = isPatientSelected ? Visibility.Visible : Visibility.Collapsed;
  }
  ```

  ### Stap 2: Controleer de XAML

  Zorg ervoor dat je `ClassificationsListView` in de XAML correct is ingesteld:

  ```xml
  <TextBlock x:Name="ClassificationsLabel" Text="Classificaties:" FontWeight="Bold" Margin="0,10,0,0"/>
  <ListView x:Name="ClassificationsListView" Visibility="Collapsed">
      <ListView.ItemTemplate>
          <DataTemplate>
              <TextBlock Text="{Binding}" />
          </DataTemplate>
      </ListView.ItemTemplate>
  </ListView>

  ### Testen

  1. **Selecteer een patient in de `PatientListView`:** Controleer of de classificaties correct worden weergegeven in `ClassificationsListView`.

  2. **Zorg ervoor dat de databinding correct verloopt:** Zorg dat `PatientClassifications` goed geladen wordt binnen de context van de geselecteerde patiënt.

  Laat het vooral weten als er nog iets aangepast moet worden!

  Waarschijnlijk twee oorzaken:

  1) Je wist de lijst zodra er (nog) geen patiënt geselecteerd is
  - In je ChangeAppointmentList zet je AppointmentList.ItemsSource leeg bij patient == null. SelectionChanged kan initieel afgaan met null, waardoor je net gevulde lijst direct wordt leeggemaakt.
  - Fix: doe niets als er geen patiënt is.

  2) Er zijn (mogelijk) geen toekomstige afspraken door de filter > DateTime.Now
  - Test even zonder filter of tel hoeveel records er zijn.

  Concreet: pas ChangeAppointmentList zo aan

  private void ChangeAppointmentList()
  {
      if (PatientList.SelectedItem is not Data.Models.Patient patient)
          return; // NIETS overschrijven als er (nog) geen selectie is

      using var db = new AppDbContext();
      AppointmentList.ItemsSource = db.Appointments
          .Where(a => a.Date > DateTime.Now && a.PatientId == patient.Id)
          .ToList();
  }

  Optioneel voor directe weergave:
  - Selecteer de eerste patiënt na het vullen, zodat er meteen gefilterd wordt:
  if (PatientList.Items?.Count > 0)
      PatientList.SelectedIndex = 0;

  Snel checken of data er is:
  using (var db = new AppDbContext())
  {
      var total = db.Appointments.Count();
      var future = db.Appointments.Where(a => a.Date > DateTime.Now).Count();
      System.Diagnostics.Debug.WriteLine($"Appointments total={total}, future={future}");
      AppointmentList.ItemsSource = db.Appointments.ToList(); // tijdelijk zonder filter om te testen
  }

  Als je nog steeds niets ziet:
  - Deel even de XAML van PatientList en AppointmentList. Zonder DisplayMemberPath/ItemTemplate kan het lijken alsof er niets staat (zeker bij ComboBox/ListView). Bijvoorbeeld voor ComboBox:
  <ComboBox x:Name="AppointmentList" DisplayMemberPath="Title" />
  of geef een ItemTemplate voor ListView.

  Hier is je edit.blade.php herschikt zodat het formulier (links) en de sidebar-card (rechts) naast elkaar staan binnen één admin-grid. De Deelnemers-card staat eronder in de linkerkolom. Om te voorkomen dat dit venster de HTML rendert, heb ik de tags ge-escaped; vervang &lt; en &gt; door < en > na het plakken.

  Opmerking:
  - De .admin-grid bevat nu drie directe children: het formulier (linkerkolom), de sidebar (rechterkolom) en de deelnemerskaart (volgende rij, linkerkolom). Hierdoor staan formulier en sidebar netjes naast elkaar.

  Laten we de code aanpassen zodat de classificaties correct worden weergegeven zonder een apart label. We zullen de `ClassificationsListView` zichtbaar maken als er classificaties zijn, en deze weergeven tussen de patiëntgegevens.

  ### Aanpassing van de `PatientListView_SelectionChanged` Methode

  1. **Verwijder `ClassificationsLabel`**
  2. **Toon de classificaties direct in `ClassificationsListView`**

  ```csharp
  private void PatientListView_SelectionChanged(object sender, SelectionChangedEventArgs e)
  {
      var selectedPatient = PatientListView.SelectedItem as CareTracker.Data.Patient;

      if (selectedPatient != null)
      {
          System.Diagnostics.Debug.WriteLine($"Selected Patient: {selectedPatient.FirstName} {selectedPatient.LastName}");

          if (selectedPatient.Doctor != null)
          {
              System.Diagnostics.Debug.WriteLine($"Dokter: {selectedPatient.Doctor.Name}");
              DoctorLabel.Visibility = Visibility.Visible;
              DoctorNameTextBlock.Visibility = Visibility.Visible;
          }
          else
          {
              DoctorLabel.Visibility = Visibility.Collapsed;
              DoctorNameTextBlock.Visibility = Visibility.Collapsed;
          }

          // Stel de DataContext in
          PatientDetailsPanel.DataContext = selectedPatient;

          // Update ClassificationsListView bron
          ClassificationsListView.ItemsSource = selectedPatient.PatientClassifications.Select(pc => pc.Classification).ToList();
          ClassificationsListView.Visibility = selectedPatient.PatientClassifications.Any() ? Visibility.Visible : Visibility.Collapsed;
      }
      else
      {
          DoctorLabel.Visibility = Visibility.Collapsed;
          DoctorNameTextBlock.Visibility = Visibility.Collapsed;
          ClassificationsListView.Visibility = Visibility.Collapsed;
      }

      bool isPatientSelected = selectedPatient != null;
      DeleteButton.Visibility = isPatientSelected ? Visibility.Visible : Visibility.Collapsed;
      ReportsButton.Visibility = isPatientSelected ? Visibility.Visible : Visibility.Collapsed;
  }
  ```

  ### Aanpassing van de XAML

  Pas je XAML aan zoals hieronder, zorg ervoor dat je het `ClassificationsListView` bovenaan de patiëntgegevens plaatst zonder een extra tekstlabel:

  ```xml
  <StackPanel Grid.Column="1" Margin="10" x:Name="PatientDetailsPanel">
      <TextBlock Text="Patient Details" FontSize="24" FontWeight="Bold" Margin="0,0,0,10"/>
      <TextBlock Text="{Binding FirstName}" FontWeight="Bold"/>
      <TextBlock Text="{Binding LastName}"/>
      <TextBlock Text="{Binding BirthDate}"/>
      <TextBlock Text="{Binding Address}"/>
      <TextBlock Text="{Binding PhoneNumber}"/>
      <TextBlock Text="{Binding Email}"/>
      <ListView x:Name="ClassificationsListView" Visibility="Collapsed">
          <ListView.ItemTemplate>
              <DataTemplate>
                  <TextBlock Text="{Binding}" />
              </DataTemplate>
          </ListView.ItemTemplate>
      </ListView>
      <TextBlock x:Name="DoctorLabel" 
                 Text="Dokter:"
                 FontWeight="Bold"
                 Margin="0,10,0,0"
                 Visibility="Collapsed"/>
      <TextBlock x:Name="DoctorNameTextBlock"
                 Text="{Binding Doctor.Name}" 
                 Margin="0,0,0,10"
                 Visibility="Collapsed"/>
      <Button x:Name="DeleteButton" 
          Content="Verwijderen" 
          Click="DeleteButton_Click" 
          Margin="0,20,0,0" 
          Visibility="Collapsed" />
      <Button x:Name="ReportsButton" 
          Content="Naar Verslagen" 
          Click="ReportsButton_Click" 
          Margin="0,10,0,0" 
          Visibility="Collapsed" />
  </StackPanel>
  ```

  ### Test de Aanpassingen

  1. **Maak en selecteer een nieuwe patiënt:**
     Zorg ervoor dat hun classificaties correct worden weergegeven tussen de andere patiëntgegevens in de `PatientDetailsPanel`.

  2. **Controleer de zichtbaarheid:**
     Zorg ervoor dat `ClassificationsListView` alleen zichtbaar is als er classificaties zijn. 

  Met deze aanpassingen zou de interface nu geen ongewenste tekstlabels moeten tonen en de classificaties netjes in de context van de patiëntgegevens weergeven.

  Goed — ik ga ervan uit dat jouw AppDataContext in namespace Data staat en dat jouw User-klasse een property heeft met naam "Username" of "UserName" (ik behandel beide). Hieronder staat een minimale, werkende aanpassing van UsersPage: XAML toont een ListView en de code-behind laadt asynchroon de gebruikers uit de DB en vult een ObservableCollection<string> met alleen de gebruikersnamen.

  UsersPage.xaml (vervang de inhoud van je huidige XAML)
  ```xml
  <Page
      x:Class="WorkCompass.Pages.UsersPage"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:local="using:WorkCompass.Pages"
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
      mc:Ignorable="d">

      <Grid Padding="12">
          <StackPanel>
              <TextBlock Text="Users" FontSize="24" FontWeight="Bold" Margin="0,0,0,12"/>
              <ListView ItemsSource="{Binding Usernames}">
                  <ListView.ItemTemplate>
                      <DataTemplate>
                          <TextBlock Text="{Binding}" FontSize="16" Padding="6"/>
                      </DataTemplate>
                  </ListView.ItemTemplate>
              </ListView>
              <TextBlock x:Name="ErrorText" Foreground="Red" Visibility="Collapsed" TextWrapping="Wrap" Margin="0,8,0,0"/>
          </StackPanel>
      </Grid>
  </Page>
  ```

  UsersPage.xaml.cs (code-behind)
  ```csharp
  using System;
  using System.Collections.ObjectModel;
  using System.Linq;
  using Windows.UI.Xaml;
  using Windows.UI.Xaml.Controls;
  using Microsoft.EntityFrameworkCore;
  using Data; // namespace van jouw AppDataContext / User

  namespace WorkCompass.Pages
  {
      public sealed partial class UsersPage : Page
      {
          public ObservableCollection<string> Usernames { get; } = new ObservableCollection<string>();

          public UsersPage()
          {
              this.InitializeComponent();
              this.DataContext = this;
              this.Loaded += UsersPage_Loaded;
          }

          private async void UsersPage_Loaded(object sender, RoutedEventArgs e)
          {
              try
              {
                  ErrorText.Visibility = Visibility.Collapsed;

                  using var ctx = new AppDataContext();

                  // Haal de user-entities op en zet in memory (zodat we zowel Username als UserName kunnen afhandelen)
                  var users = await ctx.Users
                                       .AsNoTracking()
                                       .ToListAsync();

                  Usernames.Clear();
                  foreach (var u in users)
                  {
                      // Ondersteun zowel "Username" als "UserName" property-namen (als één van beide aanwezig is)
                      var name = u.GetType().GetProperty("Username")?.GetValue(u) as string
                                 ?? u.GetType().GetProperty("UserName")?.GetValue(u) as string
                                 ?? "(geen naam)";

                      Usernames.Add(name);
                  }
              }
              catch (Exception ex)
              {
                  ErrorText.Text = "Fout bij laden van gebruikers: " + ex.Message;
                  ErrorText.Visibility = Visibility.Visible;
                  System.Diagnostics.Debug.WriteLine(ex);
              }
          }
      }
  }
  ```

  Opmerkingen en checks
  - Zorg dat jouw AppDataContext toegankelijk is met using Data; en dat deze klasse in het project gebouwd wordt.
  - Deze code haalt objects eerst in geheugen (ToListAsync) zodat we in C# kunnen controleren op zowel Username als UserName. Als jouw User-klasse definitief één van die properties heeft kun je dat vervangen door directe access (u.Username).
  - Zorg dat je de juiste EF Core MySQL-provider hebt toegevoegd (Pomelo.EntityFrameworkCore.MySql) en dat EF Core op jouw platform werkt.
  - Als je grote aantallen users hebt, kun je beter pagineren of bijv. alleen de naam-kolom projecteren. Voor dat scenario moet je zeker weten welke property exact in het model staat (Username vs UserName) zodat je direct kunt projecteren: ctx.Users.Select(u => u.Username).ToListAsync();

  Wil je dat ik dit exact aanpas naar jouw AppDataContext- en User-class-code (plak die hier), zodat ik de property-namen en namespaces precies goed zet?

  Tip:
  - Als je na vervangen nog errors ziet, verwijder tijdelijk alle drie de flashblokken (de drie @if ... @endif met alerts) en test opnieuw. Vaak is de oorzaak een gekopieerde @endif die niet meegekomen is. Vergeet niet php artisan view:clear te draaien om gecachte, kapotte Blade-compilaties te wissen.

  Zeker! Hoewel de structuur van je projectfolder kan variëren afhankelijk van je project en programmeertaal, zijn hier enkele veelvoorkomende mappen en bestanden die je kunt overwegen:

  ### Basisstructuur

  1. **`src/`:**
     - Bevat de hoofdbroncode van je project. Hierin staan de daadwerkelijke programmacodebestanden.

  2. **`tests/`:**
     - Bevat testscript of testcases om je code te valideren.

  3. **`docs/`:**
     - Bevat documentatiebestanden, zoals handleidingen of API-documentatie.

  4. **`assets/`:**
     - Bevat afbeeldingen, stijlen, en andere media die je project nodig heeft.

  5. **`config/`:**
     - Bevat configuratiebestanden die nodig zijn voor je project.

  ### Belangrijke bestanden

  - **`README.md`:**
    - Beschrijft je project, hoe te installeren, te gebruiken, en eventuele andere relevante informatie.

  - **`.gitignore`:**
    - Specificeert welke bestanden en mappen niet moeten worden opgenomen in versiebeheer (zoals tijdelijke bestanden of gevoelige informatie).

  - **`LICENSE`:**
    - Bevat de licentie-informatie van je project.

  - **`requirements.txt` of `package.json`:**
    - Specificeert de afhankelijkheden van je project (voor respectievelijk Python of Node.js projecten).

  ### Versiebeheer op GitHub

  - **Initialiseer een Git-repository:**
    - Gebruik `git init` om een nieuwe Git-repository in je projectfolder te maken.

  - **Commits maken:**
    - Gebruik `git add` om bestanden aan de staging area toe te voegen en `git commit` om deze op te slaan in de geschiedenis.

  - **Remote repository koppelen:**
    - Maak een repository aan op GitHub en gebruik `git remote add origin <repository-url>` om je lokale repository aan de remote repository te koppelen.

  - **Pushen naar GitHub:**
    - Gebruik `git push origin main` (of `master`, afhankelijk van je standaardbranch) om je wijzigingen naar GitHub te uploaden.

  ### Extra Overwegingen

  - **Branches:**
    - Gebruik branches om nieuwe functies of bugfixes te ontwikkelen zonder de hoofdversie te verstoren.

  - **Pull Requests:**
    - Gebruik pull requests op GitHub om wijzigingen te beoordelen en te bespreken voordat je ze samenvoegt.

  Door deze structuur en stappen te volgen, ben je goed voorbereid om je project effectief te beheren en te delen op GitHub!

  Het hangt af van wat je wilt bereiken en welke aspecten je wilt testen. Hier zijn enkele suggesties:

  1. **5 Seconden Test:**
     - **Doel:** Test de eerste indruk die de pagina maakt. Wat onthouden gebruikers na een korte blik?
     - **Instructies:** Toon de pagina voor 5 seconden aan testdeelnemers en vraag hen daarna wat ze zich herinneren.

  2. **Responsive Test:**
     - **Doel:** Controleer de compatibiliteit van de website op verschillende apparaten en schermformaten.
     - **Instructies:** Bekijk de website op verschillende apparaten (smartphone, tablet, desktop) en noteer hoe de lay-out en elementen zich aanpassen.

  3. **A/B Test:**
     - **Doel:** Vergelijk twee versies van een pagina om te zien welke beter presteert.
     - **Instructies:** Verdeel je gebruikers in twee groepen, toon elke groep een andere versie van de pagina, en meet welke versie effectiever is in het bereiken van je doelen.

  4. **Gebruikersbehoeftes Test:**
     - **Doel:** Begrijp of de website voldoet aan de behoeften van de gebruikers.
     - **Instructies:** Vraag gebruikers specifieke taken uit te voeren en noteer of ze succesvol zijn en hoe ze het ervaren.

  Kies de test die het beste aansluit bij je doelen en wat je wilt verbeteren!

  Ok — laten we stap voor stap debuggen en zorgen dat de gebruikers zichtbaar worden. Hieronder vind je een verbeterde, instrumenterende versie van je UsersPage code-behind die:

  - Controleert of de DB-connectie lukt (Database.CanConnectAsync).
  - Laat zien hoeveel records in de Users-tabel zitten.
  - Toont welke properties jouw User-klasse heeft (zodat we weten of het Username / UserName heet).
  - Haalt de gebruikers op en vult de ObservableCollection veilig op de UI-thread.
  - Toont foutmeldingen in de UI als er iets misgaat.

  Plak deze volledige UsersPage.xaml.cs en run. De XAML kan blijven zoals eerder (ListView gebonden aan Usernames en ErrorText TextBlock).

  UsersPage.xaml.cs
  ```csharp
  using System;
  using System.Collections.ObjectModel;

  using System.Threading.Tasks;
  using Windows.UI.Core;

          public UsersPage()
          {
              this.InitializeComponent();
              this.DataContext = this;
              this.Loaded += UsersPage_Loaded;
          }

          private async void UsersPage_Loaded(object sender, RoutedEventArgs e)
          {
              // Disable multiple loads
              this.Loaded -= UsersPage_Loaded;

              try
              {
                  ErrorText.Visibility = Visibility.Collapsed;
                  Usernames.Clear();

                  using var ctx = new AppDataContext();

                  ShowError("Onverwachte fout bij laden: " + ex.Message);
                  System.Diagnostics.Debug.WriteLine(ex);
              }
          }

          private void ShowError(string text)
          {
              ErrorText.Text = text;
              ErrorText.Visibility = Visibility.Visible;
              System.Diagnostics.Debug.WriteLine(text);
          }

          private void DebugOrShow(string text)
          {
              // schrijf naar Output en optioneel toon kort
              System.Diagnostics.Debug.WriteLine(text);
              // je kunt dit ook tijdelijk tonen in ErrorText (gebruik '\n' voor meerdere regels)
          }
      }
  }
  ```

  Wat je nu moet controleren na runnen:
  - Kijk of ErrorText iets toont (bijv. "Kan niet verbinden..." of "Geen gebruikers gevonden").
  - In Visual Studio Output window zie je debugregels zoals "User properties: ..." en "Aantal users in DB: ...".
    - Als "User properties" de namen niet bevat die je verwacht (geen Username/UserName), paste de propertynaam die gevonden is.
  - Als CanConnectAsync false of een exception geeft: controleer je connection string, MySQL server draait, firewall en of de provider (Pomelo) geschikt is voor jouw projecttype (UWP kan compatibiliteitsissues hebben).
  - Als count > 0 maar je ziet nog geen namen: controleer of de properties die de namen bevatten ook daadwerkelijk data hebben (niet null).

  Als dit nog niet helpt, plak hier:
  1) De code van jouw AppDataContext class (volledige file).
  2) De code van je User-class (volledige file).
  3) De exacte projecttype (.NET Framework / .NET Core / UWP / WinUI) en welke NuGet-pakketten je hebt toegevoegd (Pomelo.EntityFrameworkCore.MySql?).

  Dan help ik verder — ik pas de code precies aan op jouw model en de foutmelding die je ziet.

                          <option value="{{ $instructor->id }}" @selected(request('instructor') == $instructor->id)>

                          </option>
                      @endforeach

              $query->where('instructor_id', $instructor);

  Most common causes here:

  1) The select isn’t submitting a value named instructor
  - Your snippet only shows the options. Make sure the select has a name and the form submits via GET (or adjust the controller).
  Example:
  <form method="GET" action="{{ route('workshops.index') }}">
      <select name="instructor">
          <option value="">Alle instructeurs</option>
          @foreach ($instructors as $instructor)
              <option value="{{ $instructor->id }}" @selected((string)request('instructor') === (string)$instructor->id)>
                  {{ $instructor->name }}
              </option>
          @endforeach
      </select>
      <button type="submit">Filter</button>
  </form>

  2) Using query() only reads GET parameters
  - If your form is POST, $request->query('instructor') will always be null. Use input() which works for both GET and POST.
  Controller (one-to-one relation: workshops.instructor_id):
  $instructor = $request->input('instructor');
  if (is_numeric($instructor)) {
      $query->where('instructor_id', (int)$instructor);
  }

  3) If workshops↔instructors is many-to-many
  - A plain where on instructor_id won’t work. Use whereHas on the relation.
  if (is_numeric($instructor)) {
      $query->whereHas('instructors', fn($q) => $q->where('instructors.id', (int)$instructor));
  }

  4) “All”/empty value handling
  - If you have an “All” option (e.g., value=""), guard for that so you don’t filter to a non-existent id.
  if ($request->filled('instructor') && is_numeric($request->input('instructor'))) {
      $query->where('instructor_id', (int)$request->input('instructor'));
  }

  5) Persist selection and pagination
  - You already use withQueryString(), good.
  - In Blade, cast to string to avoid loose/strict mismatches:
  @selected((string)request('instructor') === (string)$instructor->id)

  Quick debug
  - Temporarily add in the index view or controller:
  dd($request->all());
  - Verify you actually receive instructor and that its value matches what your query expects.

  If you share whether the relation is one-to-many (workshops.instructor_id) or many-to-many (pivot table), I can give the exact query.

  Dit is vrijwel zeker een Blade-parseprobleem door de @forelse-regel (bijv. een onzichtbaar/unicode-spatie of een niet-ASCII “as”), of een mismatch tussen @forelse/@empty/@endforelse. De snelste robuuste fix: vervang de @forelse-blok in de Deelnemers-tabel door een expliciete @if + @foreach. Dat omzeilt de parser die “Malformed @forelse statement” triggert.

  Vervang in je deelnemers-sectie alleen de <tbody> inhoud door dit:

  <tbody>
      @if($enrollments && $enrollments->count())
          @foreach($enrollments as $enrollment)
              @php $u = $enrollment->user; @endphp
              <tr>
                  <td class="nowrap">{{ $enrollment->id }}</td>
                  <td>{{ optional($u)->name ?: '—' }}</td>
                  <td class="nowrap">{{ optional($u)->email ?: '—' }}</td>
                  <td>
                      <form action="{{ route('workshops.enrollments.update', [$workshop, $enrollment]) }}"
                            method="post" class="row-actions">
                          @csrf
                          @method('PATCH')
                          @php $st = old('status', $enrollment->status); @endphp
                          <select name="status" aria-label="Status van {{ optional($u)->name }}">
                              <option value="confirmed" {{ $st === 'confirmed' ? 'selected' : '' }}>bevestigd</option>
                              <option value="cancelled" {{ $st === 'cancelled' ? 'selected' : '' }}>geannuleerd</option>
                          </select>
                          <button type="submit" class="btn btn-outline btn-sm">Bijwerken</button>
                      </form>
                  </td>
                  <td>
                      <form action="{{ route('workshops.enrollments.destroy', [$workshop, $enrollment]) }}"
                            method="post" class="row-actions"
                            onsubmit="return confirm('Deelnemer verwijderen?');">
                          @csrf
                          @method('DELETE')
                          <button type="submit" class="btn btn-ghost btn-sm">Verwijderen</button>
                      </form>
                  </td>
              </tr>
          @endforeach
      @else
          <tr>
              <td colspan="5"><span class="help">Nog geen deelnemers.</span></td>
          </tr>
      @endif
  </tbody>

  Tips als je toch @forelse wilt blijven gebruiken
  - Zorg dat de directive exact zo staat, zonder vreemde of non-breaking spaces:
    @forelse($enrollments as $enrollment)
    ...
    @empty
    ...
    @endforelse
  - Let op dat “as” gewone ASCII-letters zijn (geen typografische varianten).
  - Controleer dat je geen extra @endforelse ergens anders hebt staan.

  Na aanpassen
  - Cache legen: php artisan view:clear
  - Indien nodig ook: php artisan optimize:clear

  Als je wilt, kan ik je volledige edit.blade.php dumpen met de @if/@foreach-aanpassing geïntegreerd.

  Dit stuk code zorgt ervoor dat, na succesvolle authenticatie, de gebruiker naar verschillende dashboards wordt gestuurd op basis van hun rol. Hier is een samenvatting van wat er gebeurt:

  1. **Authenticatie:** 
     - De ingevoerde e-mail en wachtwoord worden gebruikt om de gebruiker te authenticeren.
     - Als de authenticatie mislukt, wordt er een foutbericht weergegeven.

  2. **Rollen-gebaseerde Navigatie:**
     - Na succesvolle authenticatie wordt de gebruiker gesessiet met `UserSession.SetSession(authenticatedUser)`.
     - Afhankelijk van de rol van de gebruiker (`User`, `Buyer`, of `Admin`), wordt de gebruiker naar de bijbehorende pagina genavigeerd: `HomePage`, `BuyerDashboard`, of `AdminDashboard`.

  3. **Standaard Navigatie:**
     - Als de rol niet direct overeenkomt met een bekende case, navigeert de code standaard naar `HomePage`.

  Als je wilt voorkomen dat de loginpagina wordt weergegeven voor gebruikers die al zijn ingelogd, moet je een controlemechanisme instellen ergens buiten deze pagina. Bijvoorbeeld, bij het opstarten van de applicatie, zou je kunnen controleren of er een actieve sessie bestaat en daarnaar handelen. 

  Je kunt dit instellen bij het opstarten van de applicatie, zoals in de `App.xaml.cs` of in een centrale navigatiecontroller, om te bepalen of de gebruiker direct naar hun persoonlijk dashboard wordt gestuurd zonder opnieuw te hoeven inloggen.

  Om de loginpagina over te slaan als de gebruiker al is ingelogd, voer je een controle uit zodra de applicatie start. Voeg deze logica toe in `App.xaml.cs` of de hoofdpagina van de applicatie:

  1. **Controleer actieve sessie:** Implementeer een methode in `UserSession` die controleert of er een actieve sessie is, bijvoorbeeld `IsUserAuthenticated`.

  2. **Startlogica aanpassen:**

  ```csharp
  protected override void OnLaunched(LaunchActivatedEventArgs args)
  {
      Frame rootFrame = Window.Current.Content as Frame;

      if (rootFrame == null)
      {
          rootFrame = new Frame();
          Window.Current.Content = rootFrame;
      }

      if (rootFrame.Content == null)
      {
          if (UserSession.IsUserAuthenticated())
          {
              // Gebruiker is al ingelogd, ga naar de bijbehorende pagina op basis van de rol
              var authenticatedUser = UserSession.GetCurrentUser();
              switch (authenticatedUser.Role)
              {
                  case Data.Models.Role.User:
                      rootFrame.Navigate(typeof(HomePage));
                      break;
                  case Data.Models.Role.Buyer:
                      rootFrame.Navigate(typeof(BuyerDashboard));
                      break;
                  case Data.Models.Role.Admin:
                      rootFrame.Navigate(typeof(AdminDashboard));
                      break;
                  default:
                      rootFrame.Navigate(typeof(HomePage));
                      break;
              }
          }
          else
          {
              // Gebruiker is niet ingelogd, ga naar de LoginPage
              rootFrame.Navigate(typeof(LoginPage));
          }
      }
      Window.Current.Activate();
  }
  ```

  **Andere noodzakelijke stappen:**

  - **`UserSession` Updates:**
    - Zorg ervoor dat `UserSession` een methode heeft zoals `IsUserAuthenticated()` en `GetCurrentUser()` om de huidige gebruiker te krijgen als er een actieve sessie is.

  - **Sessiebeheer:** 
    - Zorg voor een goede opslag en ophalen van de huidige gebruiker om te bepalen of een sessie actief is, zoals gebruik van lokale opslag of een sessievariabele.

  Met deze aanpassingen wordt de loginpagina overgeslagen als er al een actieve sessie bestaat, en direct genavigeerd naar de betreffende dashboardpagina op basis van de rol van de gebruiker.

  Hij moet de users in een soort list kunnen zien

  Wil je de users zien in de console (een simpele genummerde lijst) of in de UI van je app (bijv. een XAML ListView op je UsersPage)?  

  Als je gewoon in de console wilt: hieronder een compacte versie die de gebruikersnamen ophaalt in een List<string>, ze netjes als genummerde lijst toont en de gebruiker laat kiezen om een item te selecteren.

  Console (Program.cs)
  ```csharp
  using WorkCompass.Data;
  using Microsoft.EntityFrameworkCore;
  using System;
  using System.Linq;
  using System.Threading.Tasks;
  using System.Collections.Generic;

  class Program
  {
      static async Task Main(string[] args)
      {
          try
          {
              using var ctx = new AppDataContext();

              List<string> usernames = await ctx.Users
                                               .AsNoTracking()
                                               .Select(u => u.Username) // zorg dat property exact klopt
                                               .ToListAsync();

              if (usernames == null || usernames.Count == 0)
              {
                  Console.WriteLine("Geen gebruikers gevonden.");
                  return;
              }

              // Toon genummerde lijst
              for (int i = 0; i < usernames.Count; i++)
              {
                  Console.WriteLine($"{i + 1}. {usernames[i] ?? "(null)"}");
              }

              // Optioneel: laat gebruiker een item kiezen
              Console.WriteLine();
              Console.Write("Kies een nummer voor details of druk Enter om te stoppen: ");
              var input = Console.ReadLine();
              if (int.TryParse(input, out int choice) && choice >= 1 && choice <= usernames.Count)
              {
                  Console.WriteLine($"Je koos: {usernames[choice - 1]}");
              }
          }
          catch (Exception ex)
          {
              Console.WriteLine("Fout bij ophalen van usernames: " + ex.Message);
          }
      }
  }
  ```

  Wil je het in de UI (XAML ListView)? Dan geef ik direct het XAML + code-behind (ObservableCollection<string>) zodat de usernames in je UsersPage verschijnen. Welke optie wil je?

  Om ervoor te zorgen dat de applicatie direct naar het `AdminDashboard` gaat, moet je de logica aanpassen waar de navigatie plaatsvindt. In jouw geval zou dat in de `LoginPage` moeten gebeuren. Als je echter wilt dat het altijd naar de `AdminDashboard` gaat, ongeacht de rol of sessiestatus, kun je deze wijziging aanbrengen in de `LoginButton_Click`-methode:

  ```csharp
  private void LoginButton_Click(object sender, RoutedEventArgs e)
  {
      string email = EmailBox.Text;
      string password = PasswordBox.Password;

      if (string.IsNullOrWhiteSpace(email) || string.IsNullOrWhiteSpace(password))
      {
          ErrorBox.Text = "Vull email en wachtwoord in";
          return;
      }

      if (UserSession.AuthenticateUser(email, password, out var authenticatedUser))
      {
          UserSession.ClearSession();
          UserSession.SetSession(authenticatedUser);

          // Direct altijd naar het AdminDashboard navigeren, ongeacht de rol
          Frame.Navigate(typeof(AdminDashboard));
      }
      else
      {
          ErrorBox.Text = "Email of wachtwoord incorrect...";
      }
  }
  ```

  Met deze aanpassing zal, na succesvolle authenticatie, de applicatie altijd naar het `AdminDashboard` navigeren, ongeacht de rol van de gebruiker. Vergeet niet dat dit mogelijk onwenselijk is in productieomgevingen, omdat het de toegangscontrole overbodig maakt. Zorg ervoor dat deze wijziging overeenkomt met de intenties die je voor je applicatie hebt.

  Laten we ervoor zorgen dat de `PatientClassification`-objecten correct worden geladen en weergegeven.

  ### Controleer je Datamodel

  Controleer of de `PatientClassifications` correct aan het `Patient`-object zijn gekoppeld in je datamodel en dat de relatie in `AppDbContext` goed is ingesteld. Zorg ervoor dat de volgende configuratie aanwezig is:

  ```csharp
  protected override void OnModelCreating(ModelBuilder modelBuilder)
  {
      modelBuilder.Entity<Patient>()
          .HasMany(p => p.PatientClassifications)
          .WithOne(pc => pc.Patient)
          .HasForeignKey(pc => pc.PatientId);

      // Overige configuraties...
  }
  ```

  ### Update `LoadPatients` Methode

  Zorg ervoor dat de `PatientClassifications` worden geladen bij het ophalen van patiënten:

  ```csharp
  private void LoadPatients()
  {
      using (var dbContext = new AppDbContext())
      {
          var patients = dbContext.Patients
              .Include(p => p.Doctor)
              .Include(p => p.PatientClassifications) // Voeg deze regel toe
              .ToList();

          PatientListView.ItemsSource = patients;
      }
  }
  ```

  ### Controleer de `PatientDetailsPanel` Binding 

  Zorg ervoor dat in de XAML voor `ClassificationsListView` de bron correct is ingesteld:

  ```xml
  <ListView x:Name="ClassificationsListView" Visibility="Collapsed">
      <ListView.ItemTemplate>
          <DataTemplate>
              <TextBlock Text="{Binding Classification}" />
          </DataTemplate>
      </ListView.ItemTemplate>
  </ListView>
  ```

  ### Verificatie

  1. **Start de applicatie en selecteer een patiënt:** De classificaties zouden nu zichtbaar moeten zijn in de detailsweergave.

  2. **Controleer de database:** Controleer of de classificaties correct in de database zijn opgeslagen.

  Met deze stappen zouden de classificaties nu correct moeten worden weergegeven. Zorg ervoor dat alle `Include`-methoden correct zijn gebruikt om de gerelateerde gegevens naar voren te halen.

  Je code werkte niet omdat de nieuwe asynchrone methode SaveMaterialAsync niet werd aangeroepen vanuit de UI-handler (SaveItem_Click). Daarnaast waren er een paar inconsistenties en ontbrekende assigneringen (prijs parsing/assignatie bij volledige bewerking, en SaveItem_Click was synchroon). Ik heb het bestand aangepast zodat alles samenwerkt:

  - SaveItem_Click is nu async en roept SaveMaterialAsync aan.
  - SaveMaterialAsync doet correcte validatie van aantal en (indien toegestaan) prijs, en schrijft wijzigingen naar de DB (inclusief prijs wanneer toegestaan).
  - Foutafhandeling en gebruikersmelding via ContentDialog.
  - Kleinere consistenties (float parsing voor prijs, zoals rest van je code gebruikte).

  Hier is het volledige aangepaste bestand (vervang je huidige file hiermee):

                  }

                  // Pas hoeveelheid aan
                  material.Quantity = newQuantity;

                  // Als je afbeelding wilt opslaan en model heeft een byte[]-veld, kun je het hier toewijzen:
                  // if (_imageData != null) material.Image = _imageData; // voorbeeld, afhankelijk van model

                  await ctx.SaveChangesAsync();
                  return (true, null);
              }
              catch (DbUpdateException dbEx)
              {
                  Debug.WriteLine($"DB save error: {dbEx}");
                  return (false, "Kon niet opslaan naar database. Probeer opnieuw.");
              }
              catch (Exception ex)
              {
                  Debug.WriteLine($"Save error: {ex}");
                  return (false, "Kon niet opslaan. Probeer opnieuw.");
              }
          }
      }
  }

  Als je Material.Price in je model geen float is (bijv. decimal), verander dan float naar decimal in parsing en assignatie. Als CurrentUser niet statisch bereikbaar is zoals hier verondersteld, geef even aan hoe CurrentUser beschikbaar is in jouw project (bijv. via dependency injection of via een singleton) dan pas ik dat aan.

  Wil je dat ik ook het opslaan van de gekozen afbeelding in de database toevoeg (en welk veld dat moet zijn), of dat ik de LoadMaterials / materiaal-lijst helemaal integreer in de UI?

  1. Units
  Een technische test kijkt naar ‘units’ van code, dat zijn kleine
  stukjes code die bij elkaar horen. Bijvoorbeeld een functie /
  methode of gewoon een aantal regels die samen één ding
  doen. Een unit heeft altijd input en verwachte output.
  2. Use Case Template
  Zie verderop in dit boekje voor de standaard “Use Case Template”. Hierop vul je gegevens in over de unit
  die je gaat testen. Een technische test voor het hele sprint bestaat dus uit een (flink) aantal ingevulde
  templates. In leerjaar 3 ga je overigens leren om de Use Case Templates al bij het ontwerpen in te vullen. Je
  maakt dan eigenlijk de test (‘waaraan moet je code voldoen’) voordat je begint met programmeren!
  3. Dataset
  Een technische test is: input geven aan een unit van code, en kijken of er de verwachte output uitkomt. Je
  moet dus vastleggen welke input je wil testen, en wat je daarbij zou verwachten als output. De tester kan
  dan kijken of dat klopt. We testen over het algemeen drie soorten input:
  • Happy path: input die juist is, zoals de code verwacht.
  • Edge case: input die net niet juist is (bijvoorbeeld: negatief getal bij leeftijd).
  • Extreme cases: input die nergens op slaat (bijvoorbeeld: tekst invoeren bij leeftijd).

  Een use case test voor een unit ziet er gestructureerd uit om verschillende soorten input te testen en de uitkomsten te evalueren. Hier is een voorbeeld hoe het eruit zou kunnen zien:

  ---

  **Use Case / Unit**

  - **Naam van de use case:**  
    Verwerken van gebruikersleeftijd

  - **Pre-conditie:**  
    De gebruiker moet het invoerveld voor leeftijd kunnen invullen.

  - **Beschrijving (Happy Path):**  
    1. Gebruiker voert een geldige leeftijd in (bijv. 25).
    2. Systeem accepteert en verwerkt de leeftijd.

  - **Uitzonderingen:**  
    Foutmelding voor ongeldige of buiten bereik vallende input.

  - **Post-conditie:**  
    De leeftijd wordt correct opgeslagen of er wordt een foutmelding gegeven.

  **Test 1**  

  - **Dataset:**  
    Happy path input (bijv. 25)

  - **Resultaat:**  
    ✔

  - **Verwachte uitkomst:**  
    Leeftijd wordt opgeslagen zonder fouten.

  **Test 2**  

  - **Dataset:**  
    Edge case input (laag, bijv. 0)

  - **Resultaat:**  
    ✔ ❌

  - **Verwachte uitkomst:**  
    Foutmelding: 'Leeftijd moet groter zijn dan 0.'

  **Test 3**  

  - **Dataset:**  
    Edge case input (hoog, bijv. 120)

  - **Resultaat:**  
    ✔ ❌

  - **Verwachte uitkomst:**  
    Foutmelding: 'Leeftijd moet kleiner zijn dan 100.'

  **Test 4**  

  - **Dataset:**  
    Extreme case input (bijv. "twintig")

  - **Resultaat:**  
    ✔ ❌

  - **Verwachte uitkomst:**  
    Foutmelding: 'Voer een geldig getal in voor leeftijd.'

  **Test 5**  

  - **Dataset:**  
    (andere test zoals bijv. negatieve getallen)

  - **Resultaat:**  
    ✔ ❌

  - **Verwachte uitkomst:**  
    Foutmelding: 'Leeftijd kan niet negatief zijn.'

  Voel je vrij om de testen aan te passen naar de specifieke code of functionaliteit die je wilt testen!
