SfNavigationDrawer not working with CommunityToolkit.Mvvm

Question

Hy Syncfusion Team,I use for a project the SfNavigationDrawer and set a ContentPage like suggested in this article:https://support.syncfusion.com/kb/article/15674/how-to-load-content-page-to-net-maui-navigationdrawer-contentview But in the page set as ContentView of the SfNavigationDrawer the CommunityToolkit.Mvvm seems not to work. No ObservableProperty is updated in the UI nor a RelayCommand is reaching the code in the ViewModel. Is there a special requirement for this situation?Best regardsAndreas

Hi Andreas Schramm,Thank you for
reaching out to Syncfusion support!To address the issue
you're encountering, where the CommunityToolkit.MVVM properties and commands
aren’t updating as expected within the SfNavigationDrawer ContentView, it’s
essential to assign the BindingContext of the ContentPage to the
NavigationDrawer ContentView as well. This ensures that the bindings from the
CommunityToolkit.MVVM library work correctly within the navigation drawer.Code Snippet

public partial
  class MainPage : ContentPage
  {
      private Inbox inbox;
      …
      public MainPage()
      {
          InitializeComponent();
          inbox = new Inbox();
          …
          Initialize();           
      }
   
      private void Initialize()
      {
          navigationDrawer.ContentView
  = inbox.Content;
         
  navigationDrawer.ContentView.BindingContext = inbox.BindingContext;
  …
      }
  }
