This tutorial will walk you through how you can use the Overlay Screen.

The overlay form can be activated throught the RadOverlayManager.Show() method. This method accept parameter of type Control or Form. When the Show() method is called, the Overlay form will take the size of the control which is passed as a parameter and it will appear on top of that control. This will make the control beneath the screen inactive. Rotating dots in the center will notify the user that currently a long running operation is being executed. After this operation is finished, we can close the overlay screen by calling the RadOverlayManager.Close() static method.

Show Overlay

            RadOverlayManager.Show(this.radGridView1);

RadOverlayManager.Show(Me.radGridView1)

Close Overlay

RadOverlayManager.Close();

RadOverlayManager.Close()
