A method that will handle the MailMergeFinished event of the RichEditControl.
The event source. This parameter identifies the RichEditControl, which raised the event.
A MailMergeFinishedEventArgs object which contains event data.
When creating a MailMergeFinishedEventHandler delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
