Declaration
Event Data
The GroupRowExpanded event's data class is RowEventArgs. 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. |
Remarks
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).
