CustomSummaryExistEventArgs Class

Namespace:DevExpress.Data
Assembly:DevExpress.Data.v19.1.dll

Expanded Syntax

Expanded Remarks

The DevExpress.XtraGrid.Views.Grid.GridView.CustomSummaryExists event allows you to prevent certain summaries from being calculated and displayed. Thus, it is raised when a total summary is about to be calculated or when a group summary is about to be calculated for a particular group. Summary kind can be determined using the IsTotalSummary and IsGroupSummary properties of the event argument (a CustomSummaryExistEventArgs object). When processing a group summary, the group whose summary value is about to be calculated can be identified using the GroupRowHandle property. To prevent summary value calculations, set the Exists property to false.

Note: use the Item property to access the summary item providing summary calculation settings.

CustomSummaryExistEventArgs objects are automatically created and passed to DevExpress.XtraGrid.Views.Grid.GridView.CustomSummaryExists event handlers.
