Check if the current page has been reached by pressing the back button

Question

I'm developing a little app for Windows Phone 8 that has 2 pages (1 is of course the main page).

When page2 is reached I want to check if this page has been reached by pressing the back button on the phone. I want to do something like this:

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    if (backButton.isPressed()) {
        // this page has been reached by pressing the back button on the phone
    } else {
        // this page has been reached by NavigationService.Navigate()
    }
}

Is there a native API to do that?

Be aware that the back button must exit the app on main page or your app won't be certified. So you cannot navigate from main page to page 2 via the back button. — xmashallax, Feb 28 '14 at 09:02

Is this what you need?

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    if (e.NavigationMode == NavigationMode.Back)
    {
        ...
    }
}
