NuGet Package: DevExpress.Win.Grid
public int GetParentRowHandle( int rowHandle )
Public Function GetParentRowHandle( rowHandle As Integer ) As Integer
The handle of the row whose parent row’s handle is to be obtained.
The handle of the parent group row for the specified child row.
When grouping is applied to a view, group and data rows form a hierarchy. Data rows are at the bottom hierarchy level. Using the GetParentRowHandle method for data rows will return handles of group rows corresponding to the last column within the ColumnView.GroupedColumns collection. The method can be used to go further to the top of the hierarchy. Using the GetParentRowHandle for root group rows returns the value of the GridControl.InvalidRowHandle property. Root group rows correspond to the first column within the ColumnView.GroupedColumns collection.
In server mode, the GetParentRowHandle returns the GridControl.InvalidRowHandle value if data is grouped by two or more columns.
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 GetParentRowHandle member must not be invoked for these Views. The GetParentRowHandle 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.
