Telerik UI for Windows Phone by Progress

Besides closing the RadWindow control via its IsOpen property, it can be closed also when the user clicks on the Back button of the phone or when the user taps outside of the window. Tha latter one won't be possible when using the RadWindow control in Fullscreen mode.

To toggle these two features of the RadWindow control you have to use the IsClosedOnBackButton and the IsClosedOnOutsideTap properties.

Here is an example.

<telerikPrimitives:RadWindow x:Name="radWindow" IsClosedOnBackButton="True" IsClosedOnOutsideTap="False" />
