    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()

    Hi,

    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.

    Best regards,
