The TapGestureRecognizer command working correctly in (code-behind)view but not working in viewmodel.

I wand to Execute the LoadReply method in DesignUserCommandViewModel Class using TapGestureRecognizer Command.

<Label.GestureRecognizers>
    <TapGestureRecognizer Command="{Binding Source={x:Reference Root}, Path=BindingContext.LoadReplyCommand}"/>
</Label.GestureRecognizers>

public partial class DesignUserCommandViewModel
{
    [RelayCommand]
    private void LoadReply()
    {
        Console.WriteLine("hello");
    }
}

```cs
// <auto-generated/>
#pragma warning disable
#nullable enable
namespace OnlySwipe.Maui.ViewModel.Design
{
    /// <inheritdoc/>
    partial class DesignUserCommandViewModel
    {
        /// <summary>The backing field for <see cref="LoadReplyCommand"/>.</summary>
        [global::System.CodeDom.Compiler.GeneratedCode("CommunityToolkit.Mvvm.SourceGenerators.RelayCommandGenerator", "8.4.0.0")]
        private global::CommunityToolkit.Mvvm.Input.RelayCommand? loadReplyCommand;
        /// <summary>Gets an <see cref="global::CommunityToolkit.Mvvm.Input.IRelayCommand"/> instance wrapping <see cref="LoadReply"/>.</summary>
        [global::System.CodeDom.Compiler.GeneratedCode("CommunityToolkit.Mvvm.SourceGenerators.RelayCommandGenerator", "8.4.0.0")]
        [global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]
        public global::CommunityToolkit.Mvvm.Input.IRelayCommand LoadReplyCommand => loadReplyCommand ??= new global::CommunityToolkit.Mvvm.Input.RelayCommand(new global::System.Action(LoadReply));
    }
}

Try something like that.
<Label.GestureRecognizers> <TapGestureRecognizer Command="{Binding Source={RelativeSource AncestorType={x:Type vm:MyViewModel}}, Path=MyCommand}" /> </Label.GestureRecognizers>

...assuming that you have xmlns for your viewmodel
xmlns:vm="clr-namespace:MyApp.ViewModels"

i am using Grid alt ContentView mabe that is the problem for this binding issues ?

[eqmarcin]

I've the same setup (Grid on ContentView) and it works fine for me.
Note: My BindingContext is in page via dependancy injection

public partial class MyPage : ContentPage
{
    MyViewModel _viewModel;

    public MyPage(MyViewModel viewModel)
	{
		InitializeComponent();
        BindingContext = _viewModel = viewModel;
		....

i create a new MAUI project and i test [RelayCommand], [ObservableProperty] everything working find but current working project both not working in ContentView viewModel.

i am suspecting this CollectionView for binding problem.

<CollectionView HorizontalScrollBarVisibility="Never"
                        VerticalScrollBarVisibility="Never"
                        Grid.Row="1"
                        ItemsSource="{Binding Commands}">
            
      <!-- <CollectionView.ItemsSource> -->
      <!--     <x:Array Type="{x:Type type:CommandResponse}"> -->

now i am using the ContentView ViewMode as a ItemSource and inside that ViewMode have [ObservableProperty] Model that required for UI layer data's now all binding everything working perfectly, for now i need a confirmation this the right approach or not to make this as a answer and close this issue.
