You can determine the number of details for a particular master row using the GridView.GetRelationCount method. The method’s return value decremented by one is the upper limit for the relationIndex parameter value.
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 real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.
- 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.
