Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| rowHandle | Int32 | An integer value specifying the desired group by the corresponding group row handle. |
Returns
| Type | Description |
|---|---|
| Hashtable | A Hashtable object containing summary values calculated for a particular group. |
Remarks
Key values of the returned hashtable are summary items (GridGroupSummaryItem objects). Values are the summary values calculated using the corresponding summary item’s settings. Thus, you can use index notation to access a particular summary item’s value. The desired summary item should be specified as the index parameter.
The summary text displayed within a particular group row can be obtained using the GridView.GetGroupSummaryText method. To determine the summary text displayed within a particular group footer cell, use the GridView.GetRowFooterCellText method.
Please refer to the Working with Summaries in Code. Custom Summaries topic for additional information.
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the GetGroupSummaryValues member must not be invoked for these Views. The GetGroupSummaryValues 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.
