【Vegas原创】DropdownList经典用法～～～

//初始化job_Rank         
            string strSql = "select * from code_list where pms_type='job_rank'";
            DataSet dsJobrank = DBAccess.GetDataSet(strSql);
            drpJobRank.DataSource = dsJobrank.Tables[0].DefaultView;
            drpJobRank.DataTextField = "pms_name";
            drpJobRank.DataValueField = "pms_value";
            drpJobRank.DataBind();
            drpJobRank.Items.Insert(0, new ListItem(" ", "-1"));
