string retval = "";
SqlParameter[] para = new SqlParameter[3];
para[0] = new SqlParameter("@UserName", fs.UserName);
para[1] = new SqlParameter("@EmployeeName", fs.EmployeeName);
para[2] = new SqlParameter("@ResultMessage", SqlDbType.VarChar, 500);
SqlHelper.ExecuteNonQuery(connection, CommandType.StoredProcedure, "up_proc", para);
retval = para[2].Value.ToString();
return retval;

}
}
private Data dctrl = new Data();

public string UpGridCtrl()
