Please refer to the Master-Detail Relationships and Working with Master-Detail Relationships in Code topics for additional information.

Note

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