You typically use this method to implement a way for users to drag the window when you hide the window title bar. For information about hiding the title bar and border, see How to: Configure an Application for Out-of-Browser Support.

The following code example demonstrates the use of this method.


' Handle dragging the main window.
Private Sub UserControl_MouseLeftButtonDown(ByVal sender As System.Object, ByVal e As System.Windows.Input.MouseButtonEventArgs)
    If Application.Current.IsRunningOutOfBrowser Then
        Application.Current.MainWindow.DragMove()
    End If
End Sub
