Namespace: DevExpress.XtraGrid.Views.Grid
Assembly: DevExpress.XtraGrid.v23.2.dll
NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation
Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| rowHandle | Int32 | An integer value identifying the group row by its handle. If the specified handle points to a data row this method does nothing. |
Remarks
The CollapseGroupRow method raises the GridView.GroupRowCollapsing event. This event allows you to prevent the group row from being collapsed. If a row has been collapsed, the GridView.GroupRowCollapsed event is raised.
To collapse group rows recursively use the other overload of this method.
Please refer to the Working with Groups in Code topic for additional information.
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the CollapseGroupRow member must not be invoked for these Views. The CollapseGroupRow member can only be used with Views that display real data within the Grid Control. Use the following methods to access these Views with which an end user interacts at runtime.
- GridControl.MainView - returns the top most View in a grid;
- GridControl.FocusedView - returns the focused View;
- GridControl.DefaultView - returns the currently maximized View;
- the sender parameter of View specific events;
- GridView.GetDetailView - returns a detail clone View for a specific master row.
