I've seen a Windows Phone 7 app with a window/popup which shows, after a use choice, half covering the current window, sliding in from the left while it closes when the users taps outside that window. For Windows 8x Store apps, this is a PopUp Control in a Flyout. But this is not available for Windows Phone.The regular pop-up control doesn't slide in with
<toolkit:TransitionService.NavigationInTransition>
which does work in a page-to-page transition. I have not succeeded either in closing it when I tap outside the pop-up. I tried adding LostFocus="MyEndPopUp" but that method is never called and also tried to end it on a OnNavigateFrom. What do I miss here?
If anyone could e.g. point me to some sample code doing more or less what I want would be great.
