Tcxgrid使用例子

procedure Tfrm_BarCode_makecl5.gdtv_1select_ticketPropertiesEditValueChanged(
  Sender: TObject);
 var
    i_SalesCount:Integer;
begin
  try
      ReFreshMsgInTime();
      if (bDoOldBill) then
          Exit;
     if cds_Plan.State = dsEdit    then  //cxgrid关联的数据集clientdataset为cds_Plan
        cds_Plan.Post; //必须先POST后再去Edit，否则更改的值会丢失
      cds_Plan.Edit;
     i_SalesCount := cds_Plan.FieldByName(‘select_ticket‘).AsInteger;
       cds_Plan.FieldByName(‘tfare‘).Value :=  cds_Plan.FieldByName(‘price‘).AsCurrency * i_SalesCount;
       cds_Plan.FieldByName(‘JSAllmoney‘).Value :=  cds_Plan.FieldByName(‘price2‘).AsCurrency * i_SalesCount;
   finally
     if cds_Plan.State = dsEdit    then
        cds_Plan.Post;
     CountMoney();
   end;
end;
