DataControlBase.BeginSelection() Method

Prevents selection updates until the DataControlBase.EndSelection method is called.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v24.2.Core.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public void BeginSelection()

VB.NET

Public Sub BeginSelection

Remarks

A View allows a sequence of row selection operations to be performed without having the View render itself after each modification. To do this, the code performing sequential changes must be enclosed within calls to the BeginSelection and DataControlBase.EndSelection methods. This improves performance, and avoids unnecessary rendering operations.
