    I got some error reports in my WP8 application with this information:

    System.NullReferenceException: Object reference not set to an instance of an object. at Telerik.Windows.Controls.RadWindow.TryOpen() at Telerik.Windows.Controls.RadWindow.Open() at Telerik.Windows.Controls.RadWindow.<Open>b__2()

    Can you help me find a sollution?

    RadWindow relies on the parent page. In case TryOpen is called too early in the app lifecycle, it is possible to see such error. Can you provide more details on how it is used in your code? Thank you.
