Description

Hi, I m not able to change the IsEnabled State of my Button. But if i change it with IsVisible it all works.

My xaml Page:

<Button Command="{Binding BttWeiterCommand}" IsEnabled="{Binding IsBttWeiterEnabled}" Grid.Row="1" Grid.Column="1" HorizontalOptions="Center" Text="Weiter" WidthRequest="200"/> <Button Command="{Binding BttZureckCommand}" Grid.Row="1" Grid.Column="0" HorizontalOptions="Center" Text="Zureck" WidthRequest="200"/>

My ViewModel:

//[ObservableProperty]  //also not work with CommunityToolkit
public bool IsBttEnabled{ get; set; } = true;

[RelayCommand]
        async Task BttWeiter()
        {
            try
            {
                if(IndexSelectedItem < List_InfoBoxen.Count-1)
                    IndexSelectedItem++;

                if (List_InfoBoxen[IndexSelectedItem].IsSkipButtonVisible)
                    IsBttEnabled= false;
                else
                    IsBttEnabled= true;

                //...
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception: " + ex);  
            }
            finally
            {
                   IsBttEnabled= false; //just for testing - NOT working for IsEnabled
            }
            
        }

        [RelayCommand]
        void BttZureck()
        {
            try
            {
                if (IndexSelectedItem > 0)
                    IndexSelectedItem--;

                if (List_InfoBoxen[IndexSelectedItem].IsSkipButtonVisible)
                    IsBttEnabled= false;
                else
                    IsBttEnabled= true;
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception: " + ex);
            }
            IsBttEnabled= false; //just for testing - NOT working for IsEnabled
        }
