Close RadWindow from a User control

[Don]

One of my Menu option on the MainPage.XAML is to bring up a dialog Window. The dialog window contains a User control.  Based on some  condition we need to close the dialog from the user control. How do we get hold of the running Window in the user controls and then close it.
 
Thanks Don

If you want to close it from a button you would do something like this in the buttons Click event handler:

var win = (sender as UIElement).ParentOfType<RadWindow>();
            if(win != null)
                win.Close();

 
To get access to the extension method you also have to do this:

using Telerik.Windows;
