Represents a method that will handle the RichEditControl.HyperlinkClick event.
The event sender ( a RichEditControl).
A HyperlinkClickEventArgs object that contains event data.
When creating a HyperlinkClickEventHandler delegate, you identify a method that will handle corresponding events. To associate an 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. For more information on event handler delegates, see Events and Delegates in MSDN.
