Remove Current Page

Question

Hi,

I am opening a ModalPage called MyPage22 from a page called MyPage11 this way:

await App.Current.MainPage.Navigation.PushModalAsync(new Xamarin.Forms.NavigationPage(new PlaceDetails(place_id)));

How can I remove MyPage11 before opening the MyPage22?

I tried:

async void Button_Clicked(System.Object sender, System.EventArgs e)
{
    Navigation.RemovePage(this);
    await App.Current.MainPage.Navigation.PushModalAsync(new Xamarin.Forms.NavigationPage(new MyPage22()));
}

but getting:

System.InvalidOperationException: Cannot remove root page when it is also the currently displayed page.

Hello,​

Welcome to our Microsoft Q&A platform!

System.InvalidOperationException: Cannot remove root page when it is also the currently displayed page

The page cannot be removed when it's currently displayed page. You could remove the 'MyPage11' in the OnDisAppearing() method of the 'MyPage22'. Or set the 'MyPage22' as the root page directly, which will remove the 'MyPage11' in the navigation stack.

   async void Button_Clicked(System.Object sender, System.EventArgs e)  
    {  
        App.Current.MainPage = new MyPage22();  
    }
