public class RowAllowEventArgs : RowEventArgs
Public Class RowAllowEventArgs Inherits RowEventArgs
The GridControl.GroupRowExpanding and GridControl.GroupRowCollapsing events fire when a group row is about to be expanded or collapsed respectively. They enable you to prohibit changing the row's expansion state. The RowAllowEventArgs class introduces the RowAllowEventArgs.Allow property for this purpose. The inherited RowEventArgs.RowHandle property allows you to identify the row whose expansion state is about to be changed.RowEventArgs objects are automatically created, initialized and passed to GridControl.GroupRowExpanding and GridControl.GroupRowCollapsing event handlers.
