Returns
| Type | Description |
|---|---|
| Int32 | A zero-based integer representing the row’s group level. |
Remarks
When data grouping is applied, group and data rows form a hierarchy. Data rows reside at the bottom hierarchy level. Levels of group rows depend on the position of corresponding grouping columns within the ColumnView.GroupedColumns collection. Group rows displayed at the root level correspond to the first column within that collection.
You can also obtain the group level of a row specified by its visible index. Use the GridView.GetVisibleRowLevel method for this purpose. Please refer to the Rows topic for details on row handles and visible indexes.
The image below shows a Grid View with two grouping levels:
Please refer to the Working with Groups in Code topic for additional information.
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the GetRowLevel member must not be invoked for these Views. The GetRowLevel 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.
