            con.Open();
            cmd = new SqlCommand("eT_SP_SelectType", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Type", "Daily Class");
            
            dr = cmd.ExecuteReader();
            ddl1.Items.Add("--Select--");
            ddl1.Items[0].Value = "0";
            int i = 1;
            while (dr.Read())
            {
                ddl1.Items.Add(dr[Name"].ToString());
                ddl1.Items[i].Value = dr["ID"].ToString();
