        public int p_orgcod
        {
            get

namespace nsBll{
public List<nsBo.clsorgprp> disp_rec()
        {
            nsDal.clsorg pDal = new nsDal.clsorg();
            try
            {
                return pDal.disp_rec();

What should i write in UI to display 2 fields in gridview using Template

public List<nsBo.clsorgprp> disp_rec()
        {
            if (con.State == ConnectionState.Closed)
            {
                con.Open();
            }
            SqlCommand cmd = new SqlCommand("disp_org", con);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataReader dr = cmd.ExecuteReader();
            List<nsBo.clsorgprp> obj = new List<nsBo.clsorgprp>();
            while (dr.Read())
            {
                nsBo.clsorgprp k = new nsBo.clsorgprp();
                k.p_orgcod = Convert.ToInt32(dr[0]);
                k.p_orgnam = dr[1].ToString();
                obj.Add(k);
            }
            dr.Close();
            cmd.Dispose();
            con.Close();
            return obj;
        }
