OnNavigatedTo Problem

Jul 2, 2013 at 6:47 AM
when I try to move to list page with selected basic page the basic page onnavigatedto method only invoke once and it's never been invoked again.
I use this code:

var frame = NavigationHelper.FindFrame(null, this);
        if (frame != null)
        {
            frame.Source = new Uri("Pages/AthletePage.xaml", UriKind.RelativeOrAbsolute);
        }
AthletePage.xaml is a listPage.
