Xamarin forms UWP AppViewBackButtonVisibility.Collapsed doesn't seem to work

Question

I'm using Xamarin Forms 3.6. I want to hide the back button in the UWP app. In the UWP App.xaml.cs OnLaunced I've added.

SystemNavigationManager
     .GetForCurrentView()
     .AppViewBackButtonVisibility = AppViewBackButtonVisibility.Collapsed;

I've also added it to each ContentPage (using dependency injection) so that in the constructor of each page runs the above code.

Each content page, I've also added:

NavigationPage.SetHasNavigationBar(this, false);

I always still seem to get the back button in the title bar on UWP. Any ideas in Xamarin Forms UWP how to hide and keep hidden the back button?

Answer 1

For your requirement, please invoke SetHasBackButton static method in the page where you want to hide back button like the following.

public ItemDetailPage(ItemDetailViewModel viewModel)
{
    InitializeComponent();
    NavigationPage.SetHasBackButton(this, false);
    BindingContext = this.viewModel = viewModel;
}
