I´m trying to delete an object named SelectedOrder in TableData of my viewmodel.
Binding works perfectly but when I tapped de Item to be deleted, in my viewmodel the variable SelectedOrder is null when te RelayCommand is activated…
Could you tell me why?

 <CollectionView
     ItemsSource="{Binding Orders}"
     SelectedItem="{Binding SelectedOrder}">
     <CollectionView.ItemTemplate>
         <DataTemplate>                       
                 <Frame>
                 <Frame.GestureRecognizers>
                     <TapGestureRecognizer Command="{Binding Source={RelativeSource AncestorType={x:Type viewmodels:MainPageViewModel}}, Path=DeleteOrderCommand}" NumberOfTapsRequired="1" />
                 </Frame.GestureRecognizers>
                 <Label
                     FontSize="Medium"
                     HorizontalOptions="Start"
                     Text="{Binding Id}"
                     VerticalTextAlignment="Center" />                               
                 </Frame>                       
         </DataTemplate>
     </CollectionView.ItemTemplate>
     <CollectionView.ItemsLayout>
         <LinearItemsLayout ItemSpacing="5" Orientation="Vertical" />
     </CollectionView.ItemsLayout>
 </CollectionView>

 [ObservableProperty]
 private Order selectedOrder;


 [RelayCommand]
 private async Task DeleteOrder()
 {          
     App.OrdersRepo.TestDeleteItem(SelectedOrder);

     Orders = await App.OrdersRepo.TestGetItems();
 }

Where is the problem?
