GridControl.StartGrouping Event

Occurs before a grouping operation is started. This is a routed event.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v14.2.dll

Declaration

C#

public event RoutedEventHandler StartGrouping

VB.NET

Public Event StartGrouping As RoutedEventHandler

Event Data

The StartGrouping event's handler receives an argument of the RoutedEventArgs type. The following properties provide information specific to this event:

Property	Description
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.
Source	Gets or sets a reference to the object that raised the event.

Remarks

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

• Fires the GridControl.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.
