Q&A #42 – Is Forward Navigation supported in Windows Phone?
The NavigationService in the ApplicationPhonePage includes the methods GoBack () and Go Forward () but the method Go Forward () does not allow the user to do the forward navigation.
When the NavigationService.GoForward () is used, the “InvalidOperationException” is raised.
An exception of type ‘System.InvalidOperationException’ occurred in Microsoft.Phone.ni.dll but was not handled in user code
Additional information: Cannot go forward when CanGoForward is false.
