从应用程序中的一个页面导航到另一个页面时，为什么会丢失导航返回条目？

Question

I have two pages: Page1.xaml and Page2.xaml. Page1.xaml has a listbox in which, when a user selects an item, I do a NavigationService.Navigate(new Uri("/Page2.xaml", UriKind.Relative)); .

But from Page2.xaml, when I press the hardware Back button, it simply exits the application. Page1.xaml is the startup page of the application.

Answer 1

There was an exception when I pressed the Back button on the second page, which was causing the application to close. I never debugged this part and hence never realized.
