Declaration

Boolean | true if the master row can be collapsed; otherwise, false. |
Remarks
This member supports the grid control’s internal infrastructure and is not intended to be used from your code.
The method returns false if the master row is collapsed already. Otherwise, the method raises the GridView.MasterRowCollapsing event to determine whether collapsing is allowed.
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the CanCollapseMasterRowEx member must not be invoked for these Views. The CanCollapseMasterRowEx 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.
