GridView.UpdateSummary() Method

Updates both group summaries and total summaries.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v21.2.dll

NuGet Packages: DevExpress.Win.Design, DevExpress.Win.Grid

Declaration

C#

public void UpdateSummary()

VB.NET

Public Sub UpdateSummary

Remarks

Please refer to the GridView.UpdateGroupSummary and GridView.UpdateTotalSummary method descriptions for information on when manual summary updates are required.

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the UpdateSummary member must not be invoked for these Views. The UpdateSummary member can only be used with Views that display real data within the Grid Control. Use the following methods to access these Views with which an end user interacts at runtime.

• GridControl.MainView - returns the top most View in a grid;
• GridControl.FocusedView - returns the focused View;
• GridControl.DefaultView - returns the currently maximized View;
• the sender parameter of View specific events;
• GridView.GetDetailView - returns a detail clone View for a specific master row.
