Property Value

Type	Default	Description
ASPxSummaryItemCollection	*null*	An ASPxSummaryItemCollection object that represents the collection of group summary items.

Remarks

Group summaries are displayed within group rows when data grouping is applied. Summary items are represented by the ASPxSummaryItem objects and are stored within the GroupSummary collection. This collection provides methods and properties that allow you to add, remove and access summary items.

Note

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