quoted text from previous thread:
Your second question should really be a new thread. Back buttons will cancel out of the prompt. It will cause the prompt to fire off the completed event but you can determine it is a cancel event by the PopUpEventArgs
via something like: e.PopUpResult ==
If you look at the prompts.xaml.cs in the test application, you can see examples of this.
I missed it before, but this is indeed the case when pressing the back button
1st time: it clear the SIP
2nd time: it fire the completed event with cancel event
Is it possible to unite these two actions to one - I assume the user expect to clear the prompt when he press the back button for the 1st time.
