Question

I have inherited some Windows Phone code that I must change. I need to show the user a tutorial about how to use the application when he first launches it. However, I cannot manage to change the current view…

Here is my code:

    public LoginView()
    {
        InitializeComponent();
        this.DataContext = new LoginViewModel();
        if (ApplicationFirstLaunched() == true)
        {
           NavigationManager.Current.Navigate(ApplicationView.DemoView);
        }
    }

The ApplicationFirstLaunched function works fine (I use IsolatedStorageSettings to store a boolean value), but the view never changes.. I thought that maybe the Navigate call was wrong so I created a button in my view and assigned its Click property to this function:

 private void demoBtn_Click(object sender, RoutedEventArgs e)
 {
    NavigationManager.Current.Navigate(ApplicationView.DemoView);
 }

When I click the button, the view changes and the tutorial pops up. What to do to show another view at first launch? Thanks

Navigate in the OnNavigatedTo method.

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    if (ApplicationFirstLaunched() == true)
    {
       NavigationManager.Current.Navigate(ApplicationView.DemoView);
    }
}
