How can I control if a button is visible in code.

<buttons:BindableButton BindingContext="{Binding  Close_Page_Clicked}"

                                    HorizontalOptions="EndAndExpand"  IsVisible="{Binding IsReturnVisible}"

                                    BackgroundColor="White" TextColor="Black" BorderWidth="1"  BorderColor="Black" />


    private bool _isReturnVisible = false;   // button is visible when page loads

    public bool IsReturnVisible


        get => _isReturnVisible;



            SetProperty(ref _isReturnVisible, value);


 _isReturnVisible = false; // also does not work

    Because you have set the BindingContext="{Binding Close_Page_Clicked}" for your button and

    you have set the   IsVisible="{Binding IsVisible}" in your BindableButton.xaml.

    If you need to make the BindableButton to disappear, you need to change it in your ViewModel.

    For example, You can set the false in the CollectionPageModel.cs 's constructor.

    ButtonModel buttonModel=   new ButtonModel("Close App", CloseAppAction, false); ;
    Close_App_Clicked = buttonModel;

    If you change it at runtime, set the buttonModel.IsVisible = true; in your background code.

    Xamarin support will end on May 1, 2024, it's recommended that you migrate your Xamarin app to .NET MAUI. Please see Xamarin official support policy .
