//and my 3 tier coding is as follows=====
public List<clslandprp> dspland(clslandprp r)
{
SqlCommand cmd = new SqlCommand("dspland", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@propertyid", SqlDbType.Int).Value = Convert.ToInt32(r.propertyid);
if (con.State == ConnectionState.Closed)
{
con.Open();
}
SqlDataReader dr = cmd.ExecuteReader();
List<clslandprp> lst = new List<clslandprp>();
if (dr.HasRows)
{
dr.Read();
clslandprp k = new clslandprp();
k.priceland = Convert.ToInt32(dr[1]);
k.sqrft = Convert.ToInt32(dr[2]);
k.Pimage = dr[3].ToString();
k.propertytype = dr[4].ToString();
k.location = dr[5].ToString();
lst.Add(k);

}
cmd.Dispose();
