I have lots of pages in my app . When I click back button it does not navigate to previous page but it navigate to the lock screen where all apps are present . Should I have to write code for back button for navigation??

  • Are you targetting Silverlight or WinRT? Are you using NavigationHelper? Have you subscribed to `HardwareButtons.BackPressed`? – Romasz Jul 23 '14 at 18:51
  • WinRT i am just checking the default behaviour. – Ghazanfar Khan Jul 23 '14 at 19:06
  • Can you provide sample code – Ghazanfar Khan Jul 23 '14 at 19:13

    What sample code? I thought you can provide some :) Please check your app.xaml.cs for eventhandler `HardwareButtons_BackPressed` also check if you hadn't subscribed somewhere to this event elsewhere, especially please check if you have a folder called `Common` and `NavigationHelper.cs` there. If you don't have them, you can add *Basic Page* to your project and this will add some helper files. – Romasz Jul 23 '14 at 19:16

Yes you need to override OnBackKeyPress of the phone to handle where the back button should navigate to.

AddHandler HardwareButtons.BackPressed, AddressOf HardwareButtons_BackPressed

Private Sub HardwareButtons_BackPressed(sender As Object, e As BackPressedEventArgs)
    e.Handled = True
    YourGoBackCode()
End Sub

And same in c#

HardwareButtons.BackPressed += HardwareButtons_BackPressed;

private void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
{
   e.Handled = true;
   YourGoBackCode();
}
