DataControlBase.BeginDataUpdate() Method

Prevents visual and internal data updates until the DataControlBase.EndDataUpdate method is called.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v18.2.Core.dll

Declaration

C#

public void BeginDataUpdate()

VB.NET

Public Sub BeginDataUpdate

Remarks

To prevent internal data updates, use the BeginDataUpdate and DataControlBase.EndDataUpdate methods. This allows you to improve the control’s performance when sorting or grouping by a column, adding, deleting, or modifying records at the data source level, etc.

If the code that performs a sequence of any of these operations is wrapped with the BeginDataUpdate and DataControlBase.EndDataUpdate methods, the grid performs only a single data update, reflecting all changes made, after the DataControlBase.EndDataUpdate method is called.
