NavigationService remove complete back navigation

Question

Using NavigationService.RemoveBackEntry() I can remove one entry from the navigation stack. Is there a convenient way to remove all back navigation items in my app (scenario: I have a sign-up procedure which consists of multiple pages, and after successful registration I do not want the user to navigate back to the registration steps).

Answer 1

It's not that inconvenient to do that with RemoveBackEntry:

while(NavigationService.CanGoBack)
{
    NavigationService.RemoveBackEntry();
}

Answer 2

Or use this, a single line code

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
    {
        base.OnNavigatedTo(e);
        while (NavigationService.RemoveBackEntry() != null) ;
    }
