InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.

Remarks

Use the MasterRowCollapsed and GridControl.MasterRowExpanded events to perform additional processing after a master row has been collapsed or expanded.

To specify whether an individual row can be collapsed or expanded, handle the GridControl.MasterRowCollapsing and GridControl.MasterRowExpanding events respectively.
