GridControl.StartGrouping Event

Occurs before a grouping operation is started.

Namespace: DevExpress.UI.Xaml.Grid

Assembly: DevExpress.UI.Xaml.Grid.v19.2.dll

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.
