Represents a method that will handle the TreeList.CustomDrawRowFooter event.
The event sender (typically the TreeList control).
A CustomDrawRowFooterEventArgs object that contains data related to the event.
When you create a CustomDrawRowFooterEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
