ColumnView.StartGrouping Event
Fires before a grouping operation is started.
Namespace: DevExpress.XtraGrid.Views.Base
Assembly: DevExpress.XtraGrid.v19.2.dll
Declaration
[DXCategory("Sorting")]
public event EventHandler StartGrouping<DXCategory("Sorting")>
Public Event StartGrouping As EventHandlerEvent Data
The StartGrouping event's data class is EventArgs.
Remarks
When you group data by a specific column, the View does the following:
- raises the StartGrouping event;
- performs data grouping;
- raises the ColumnView.EndGrouping event.
Note that data grouping requires sorting to be performed. Thus, the ColumnView.StartSorting and ColumnView.EndSorting events are also raised before and after grouping. Note that you can use the ColumnView.BeginSort and ColumnView.EndSort methods to suppress these events when performing sequential sorting and grouping operations.
See the Grouping document for more information.
