Hurra, I found it!

At the end of the App constructor we add an event handler to the Navigating event

RootFrame.Navigating + = new NavigatingCancelEventHandler (RootFrame_Navigating);

and every time we started, we finalize or change view or page pass through this event,

the event is:

private void RootFrame_Navigating (object sender, NavigatingCancelEventArgs e)
{
/ / e.Uri has the complete application uri
/ / MessageBox.Show (e.Uri.ToString ());
}

I've discovered thanks to these two urls:

Hello Andrea,

I have been for a few days looking for information about this subject and I could not find anything.

let me explain:

I have an application that uses live tiles,
what I do normally is in the view (PhoneApplicationPage) pointed from live tile application in it´s method OnNavigatedTo, I ask for the parameters I need to know about the live tile parameters:

for example:
if (NavigationContext.QueryString.TryGetValue ("panoramaItem" panoramaItem out))
             {
                 panoramaItem = "0";
             }

So far so good, but I need to do this same check in the App.xaml.cs. Application_Launching

can it be done in App.xaml.cs?, Or can I know parameters that have started the application?

Thank you very much for your help!

Thanks for clarifying points about BackStack policy however when you say "forward-navigate", do you refer to "Navigate()" or "GoForward()" method or both?

Ha I found the problem, my Panorama page was in a separate assembly, and there wasn't a reference to the Microsoft.Phone.Controls assembly in the main assembly. No it works ;)

Hi,

Do you know if the Panorama and Pivot pages could be used in navigation scenario. For example: I have a main page and I wanna navigate to a second page. When that second page contains Panorama (or Pivot) controls, it always throws an exception. But if I use a normal page everything works perfect. I am unable to find any useful information over the web. All tutorials I've seen demonstrate the Panorama as a home screen of the application and it will be quite strange if it is not possible to use it as a second page (for example).
