virtual int __fastcall GetAggRecordCount(TGroupPosInd Grp);
Description
Returns the number of aggregate fields.
GetAggRecordCount returns the number of aggregate fields from a group. The Grp parameter represents the position of the record within the group. The method returns 0, so every TDataSet descendant must override this method in a specific way.
