        {
            //得到市级城市列表
            BLL.DeviceGroup bllDG = new BLL.DeviceGroup();
            DataSet ds1 = bllDG.GetCity();  //此处得到groupName,groupID.比如:西宁,"03"
            DropDownList1.Items.Add(new ListItem("请选择", ""));
            if (ds1.Tables[0].Rows.Count > 0)
            {
                foreach (DataRow dr in ds1.Tables[0].Rows)
                {
                    DropDownList1.Items.Add(new ListItem(dr["groupName"].ToString(), dr["groupID"].ToString()));
