NuGet Package: DevExpress.Web

Declaration

[DefaultValue(null)]
public ASPxSummaryItemCollection TotalSummary { get; }

Property Value

Type Default Description
ASPxSummaryItemCollection null

An ASPxSummaryItemCollection object that is the collection of summary items.

Remarks

Total summaries are displayed within footer cells provided that the ASPxGridViewSettings.ShowFooter option is set to true. The total summary represents a value of an aggregate function calculated over all data rows displayed within the ASPxGridView.

Note

In server mode, a summary cannot be calculated for unbound columns whose values are calculated via events (see ASPxGridView.CustomUnboundColumnData). Only columns with unbound expressions (see GridViewDataColumn.UnboundExpression) support summary calculation.
