Remarks

This method allows you to return group summary values for the summaries that have already been calculated. You can call this method when the CustomSummaryEventArgs.SummaryProcess property returns CustomSummaryProcess.Finalize.

Group summaries are calculated in the order in which they have been specified. For instance, in the GridControl, group summaries are calculated in the order specified by the position of the corresponding items in the GridView.GroupSummary collection. If the CustomSummaryCalculate event is currently firing, say, for a third summary item, the GetGroupSummary method can be called to retrieve summary values for the first and second summary items, as they have already been calculated.
