Remarks

Important

This documentation topic describes legacy technology. We no longer develop new functionality for the GridControl and suggest that you use the new DataGridView control instead.

Before a group row is collapsed, the GridControl.GroupRowCollapsing event is raised, allowing you to cancel the action. After a group row has been collapsed, the GridControl.GroupRowCollapsed event is raised.

To collapse all group rows, use the GridControl.CollapseAllGroups method.

To expand group rows, use the GridControl.ExpandAllGroups or GridControl.ExpandGroupRow method.
