Event Data

The GroupRowExpanded event handler receives an argument of the RowEventArgs type. The following properties provide information specific to this event.

Property Description
Row Gets the processed row.
RowHandle Gets the processed row's handle.
Source Gets the grid that raised the event.


The GroupRowExpanded event is raised after a group row has been expanded by an end-user or in code. The group row is identified by its handle via the RowEventArgs.RowHandle property. This event serves as a notification, and the action cannot be cancelled. To control whether individual group rows can be expanded, handle the GridControl.GroupRowExpanding event.

The GridControl.ExpandAllGroups method allows you to expand all group rows. In this instance, the GroupRowExpanded event is raised only once. The event parameter's RowEventArgs.RowHandle property returns an invalid row handle (DataControlBase.InvalidRowHandle).
