页面多Grid同时修改写法

前台三个DO事件，预处理，处理以及取消事件

预处理中判断是否选中记录，因为是两个Grid，用两个if判断选中记录的行数，如果页面有新增按钮的话需要去除页面新增的数据代码在修改代码下面，若页面无修改则不用加

#region 修改

后台对应的代码如下，判断两个grid是否都有改动（判断inblock中的表数据是否有值）

try
    {
        //获取前台输入数据
        colsname1 = bcls_rec->Tables[2].Rows[0]["COLSNAME1"].ToString().Trim();//需要查询的列
        Log::Trace("", __FUNCTION__, "colsname1={0} ", colsname1);
        colsname2 = bcls_rec->Tables[2].Rows[0]["COLSNAME2"].ToString().Trim();//需要查询的列
        Log::Trace("", __FUNCTION__, "colsname2={0} ", colsname2);
        if (bcls_rec->Tables[0].Rows.get_Count() > 0){
            Log::Trace("", __FUNCTION__, "修改={0} ", "制造命令信息");
            for (int i = 0; i < bcls_rec->Tables[0].Rows.get_Count(); i++)
            {
                // 取得单行传入信息 
                tpssmma01.Reset();
                tpssmma01.MergeFrom(bcls_rec->Tables[0].Rows[i]);

                //设置修改者信息
                tpssmma01.REC_REVISOR = s.userid;
                tpssmma01.REC_REVISE_TIME = datetimeNow;
                tpssmma01.Update('"'+colsname1+'"', " PONO");
                
            }
            if (bcls_rec->Tables[1].Rows.get_Count() > 0){
                Log::Trace("", __FUNCTION__, "修改={0} ", "板坯命令信息");
                for (int i = 0; i < bcls_rec->Tables[1].Rows.get_Count(); i++)
                {

                    tpssmma03.Reset();
                    tpssmma03.MergeFrom(bcls_rec->Tables[1].Rows[i]);

                    tpssmma03.Update(colsname2, " PONO");
                    
                }
            }
        }
        
    }
    catch (CDbException& ex)  //捕获数据库操作异常
    {
        CFormattable arguments[] = { ex.GetCode() };
        CMessageFormat::Format(s.msg, _RES("GCRSS0000021")/*信息读取失败。*/, arguments, 1);
        CString str = sqlstr + "\r\n" + ex.GetMsg();
        strncpy(s.sysmsg, (const char*)str, sizeof(s.sysmsg) - 1);
        s.flag = -1;
        doFlag = -1; //数据库异常时返回-1，事务将被回滚
    }
    catch (const CApplicationException& ex)
    {
        s.flag = ex.GetCode();
        doFlag = -1;
    }
    catch (CException& ex)
    {
        strncpy(s.msg, (const char*)ex.GetMsg(), sizeof(s.msg) - 1);
        s.flag = ex.GetCode();
        doFlag = -1;
    }

    return(doFlag);
