GridControl.StartGrouping Event

Occurs before a grouping operation is started.

Namespace: DevExpress.WinUI.Grid

Assembly: DevExpress.WinUI.Grid.v23.2.dll

NuGet Package: DevExpress.WinUI

Declaration

C#

public event EventHandler StartGrouping

VB.NET

Public Event StartGrouping As EventHandler

Event Data

The StartGrouping event's data class is EventArgs.

Remarks

Each time the grid’s data is grouped or ungrouped by a column, the grid does the following:

• Fires the StartGrouping event.
• Performs data grouping.
• Fires the GridControl.EndGrouping event.

Since data grouping requires sorting, the GridControl.StartSorting and GridControl.EndSorting events are also raised before and after grouping.
