急救：请教高手数据相加的问题！

Question

gridview1:
       date          shipID   departmentID   worktypeID   actualHour_today    actualWeight_today
2008-4-5  0:00:00    200804        01           0101          23                   34
2008-4-10 0:00:00    200804        01           0101          11                   23
2008-4-15 0:00:00    200804        01           0101          33                   45
gridview2:
     year    month    shipID     departmentID    worktypeID  actualHour_current   actualWeight_current
    2008       4      200804           01          0101           67                    102计算结果存在table.stat中：
        date          shipID     departmentID    worktypeID  actualHour_current   actualWeight_current
 2008-4-1 0:00:00      200804           01          0101           67                    102
gridview1   是由collection的table根据date\shipID\departmentID\worktypeID查询得到的

Answer 1

在绑定的时候得到DataSet或者DataTable然后看下面的代码··自己改吧
 double dd = 0;
                        double dh = 0;
                        DataTable tranDT=new DataTable ();
                        tranDT = BindDataWithSNToDataTable(DealOID.Value, out dd, out dh);
                        foreach (DataRow dr in dt2.Rows)
                        {
                            DataRow r = tranDT.NewRow();
                            r["TSN"]=dr["TSN"];
                            r["TOID"] = dr["TOID"];
                            r["POID"] = dr["POID"];
                            r["TSubTotal"] = dr["TSubTotal"];
                            r["TCheckScore"] = dr["TCheckScore"];
                            r["TLTotal"] = dr["TLTotal"];
                            r["PSN"] = dr["PSN"];
                            r["PCompanyName"] = dr["PCompanyName"];
                            r["PSubTotal"] = dr["PSubTotal"];
                            r["PDCheckScore"] = dr["PDCheckScore"];
                            r["PPCheckScore"] = dr["PPCheckScore"];
                            r["PLCheckScore"] = dr["PLCheckScore"];
                            r["PLTotal"] = dr["PLTotal"];
                            r["TPSN"] = dr["TPSN"];
                            r["PPSN"] = dr["PPSN"];
                            r["PCSN"] = dr["PCSN"];
                            tranDT.Rows.Add(r);
                        }
                        transD = 0;
                        deliverD = 0;
                        //dt2.Rows.CopyTo(tranDT.Rows, 0);
                        foreach (DataRow r  in tranDT.Rows )
                        {
                            if (r["TLTotal"].ToString () != null && r["TLTotal"].ToString () != "")
                            {
                                transD = transD + Convert.ToDouble(r["TLTotal"]);
                            }
                            if (r["PLTotal"].ToString () != null && r["PLTotal"].ToString () != "")
                            {
                                deliverD = deliverD + Convert.ToDouble(r["PLTotal"]);
                            }
                        }
                        TransportSignBillSummary.DataSource = tranDT;
                        TransportSignBillSummary.DataBind();

不是很明白……可能是我太菜了用lable和textbox解决了还是谢谢各位！！
