GridView.CollapseAllGroups() Method

Collapses all groups.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v22.2.dll

NuGet Package: DevExpress.Win.Grid


public virtual void CollapseAllGroups()


The method collapses all group rows within the current View. Only the top level group rows are then visible. End-users can do this also by using the group panel context menu.

If you need to collapse a particular group row via code, use the GridView.SetRowExpanded method.


Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the CollapseAllGroups member must not be invoked for these Views. The CollapseAllGroups 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.
