    Hello Telerik Team,

     

    1. Start the "Telerik Examples" project in Visual Studio (on real device or emulator)
    1. Choose "browse all controls" and than anyone from  the list. For example "Dock Panel"
    2. Choose "view info" from the "..." menu
    3. Hit "Windows" Device Button
    4. Hit "Back" Device Button
    5. Close "View Info" Dialog with "X"
    6. NullReferenceException occurs.

     

    Instead of point 4 and 5, you can switch off (standby) and on the device.

     

     

    System.NullReferenceException:
