GridControl.GroupRowExpanded Event

Occurs after a group row has been expanded.

Namespace: DevExpress.Mobile.DataGrid

Assembly: DevExpress.Mobile.Grid.v18.2.dll


public event RowEventHandler GroupRowExpanded
Public Event GroupRowExpanded As RowEventHandler


The GroupRowExpanded event is raised after a group row has been expanded by an end-user or in code. This event serves as a notification and the action cannot be canceled. To control whether individual group rows can be expanded, handle the GridControl.GroupRowExpanding event. For instance, to prevent a group row from being expanded, set the GroupRowExpanding event parameter's RowAllowEventArgs.Allow property to false.

The GridControl.ExpandAllGroups method allows you to expand all group rows. In this instance, the GroupRowExpanded event is raised for each group.
