See Question&Answers more detail:osThis topic is one of the examples used in the Guide to Universal Windows Platform apps . I strongly suggest reading that when getting started with Universal apps.
For the button on the page header use Windows.UI.Core.SystemNavigationManager and set the AppViewBackButtonVisibility property to show or hide the button and handle the BackRequested event to perform the navigation.
Windows.UI.Core.SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility = AppViewBackButtonVisibility.Visible;
Windows.UI.Core.SystemNavigationManager.GetForCurrentView().BackRequested += (s,a) =>
{
Debug.WriteLine("BackRequested");
if (Frame.CanGoBack)
{
Frame.GoBack();
a.Handled = true;
}
}
You wire up the hardware back button the same as you do in Windows Phone 8.1, but you should check for the PhoneContract (or the individual class and method) to make sure it is there:
if (ApiInformation.IsApiContractPresent ("Windows.Phone.PhoneContract", 1, 0)) {
Windows.Phone.UI.Input.HardwareButtons.BackPressed += (s, a) =>
{
Debug.WriteLine("BackPressed");
if (Frame.CanGoBack)
{
Frame.GoBack();
a.Handled = true;
}
};
}
