MVVM and Navigation --- full on PEBCAK?

XamtasticXamtastic ✭✭✭Member ✭✭✭

I am trying to Navigate to another Page in a View because this control is HUGE and copy/paste is so 1997.

Running the code below I get an error:
"PushAsync is not supported globally on Windows, please use a NavigationPage."

`
public class MyViewModel
{
INavigation _navigation;

    public Command GotoCommand { get; private set; }
    async Task ExecuteGotoCommand()
    {
        _await _navigation.PushAsync( new NavigationPage( new MyNextPage() ) );
    }

    public MyViewModel(INavigation navigation) 
    {
        _navigation = navigation;
        GotoCommand = new Command(async () => await ExecuteGotoCommand());
    }
}

`
Also get error with:

  • App.Current.MainPage.Navigation
  • without "new NavigationPage"

    If it helps, there is an attached property from NavigationPage for something like SetHasNavigationBar you can set to false on your Page. I don't have the exact name in front of me, but just check the properties of the NavigationPage and you will find it.
