//获取chech box ID
        protected string GetProtoID()
        {
            string protoId = "";
            //获取选中的记录Id
            List<object> lSelectValues = ASPxGridView2.GetSelectedFieldValues("PROTOCOLPRICE_ID");   //获取选中的行id
            for (int i = ; i < lSelectValues.Count; i++)
            {
                protoId += lSelectValues[i] + ",";       //记录有多个，已‘，’隔开
            }
            // delId = delId.Substring(0, delId.LastIndexOf(','));

            return protoId;

        }
　　　　//提交按钮
        protected void ASPxCallback2_Callback(object source, DevExpress.Web.ASPxCallback.CallbackEventArgs e)
        {
            string ck_id = GetProtoID();
            int n = marketbll.Get_GetsellProtoDep(ck_id, PEOID.ToString());  //调取存储过程
            if (n > )
            {
                ASPxCallback2.JSProperties["cpmess"] = "恭喜！发布成功！";
            }
