Detecting fullsize screen

Question

The sample map toolbar includes a button to switch the browser to full screen mode. The user presses ESC to return to normal view. Is there a way to detect this return to normal view so some of the features can be adjusted or turned off at that time?

Thanks

I found it. Here it is. Private Sub MainPage_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded
   AddHandler App.Current.Host.Content.FullScreenChanged, AddressOf fullScreenChanged
 End Sub

Private Sub fullScreenChanged()
  If Not App.Current.Host.Content.IsFullScreen Then
   Logo.Visibility = Visibility.Collapsed
  End If
 End Sub

Thanks Dan. Your sample will detect the state but that's not what I need. What I need is to detect that the state has changed. (a trigger) The link you provided seems to discuss this but I can't make much sense of it. Do you have a sample of how to trigger an event when the state changes?
Thanks

This event is fired whenever the fullscreen state is toggled:
    Application.Current.Host.Content.FullScreenChanged
