Question

I have something like this :

SplashPage -> MainPage -> Settings -> About

SplashPage is only page with my logo and animation for about 1 second, and then I redirect my user to MainPage. First problem was that when I press back button on MainPage, I’m back to splashpage and that wasn’t good. I solved that by this piece of code :

private bool navigateBack;

        public SplashPage()
        {
            InitializeComponent();

            navigateBack = false;
        }

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            if (navigateBack)
            {
                this.NavigationService.GoBack();
            }
            else
            {
                navigateBack = true;
                base.OnNavigatedTo(e);
            }
        }

This way on back button press, user never see splashpage again, but I have weird problem. Application is throwing Navigation Exception that CanGoBack property is false and application exit. It’s true, that I want to exit from app, but not using exception, because I will fail certification in marketplace.

My question is how to navigate back from MainPage and exit application, but with no exception thrown. Thank you in advance!

Answer 1

Introducing a separate page for your splash screen introduces more problems than it solves (as you’re finding out), so I’d reccomend using an overlay on your main page instead. I [posted about using splash screens and this very situation a while back.
