Boolean | true if the master row’s default detail View is empty; otherwise, false. |
Remarks
This method determines whether the detail clone identified by the GridView.DefaultRelationIndex property value has data. It uses the GridView.IsMasterRowEmptyEx method internally. Please refer to the latter method’s description for details.
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the IsMasterRowEmpty member must not be invoked for these Views. The IsMasterRowEmpty 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.
