Returns the row's group level.
public virtual int GetRowLevel( int rowHandle )
Public Overridable Function GetRowLevel( rowHandle As Integer ) As Integer
An integer value the row by its handle.
A zero-based integer representing the row's group level.
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.
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 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.
