Represents a method that will handle the NavBarGroup.CalcGroupClientHeight event.
An object representing the source of the event (typically a NavBarGroup object representing the group whose client height is calculated).
A NavBarCalcGroupClientHeightEventArgs object that contains event data.
When you create a NavBarCalcGroupClientHeightEventHandler 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.
