A method that will handle the XRControl.Draw event.
public delegate void DrawEventHandler( object sender, DrawEventArgs e );
Public Delegate Sub DrawEventHandler( sender As Object, e As DrawEventArgs )
The source of the event.
When creating a DrawEventHandler delegate, you identify the method that will handle the corresponding event. To associate the event with your event handler, add a delegate instance to the event. The event handler is called whenever the event occurs unless you remove the delegate.
