  SetMenu();
  // WebDataMenuMain.Items.Add(""); // when I add this line, the last item will can be appeare
}

private void SetMenu()
{
  DataTable dt = GetData(); // GetData result structure is a DataTable(Columns: ID, Name, ParentID)
  DataSet ds = new DataSet();
  ds.Tables.Add(dt);
  ds.Relations.Add("NodeRelation", ds.Tables[0].Columns["ID"], ds.Tables[0].Columns["ParentID"]);
  foreach (DataRow dr in dt.Rows)
  {
    if (dr["ParentID"] == DBNull.Value)
    {
      DataMenuItem newItem = new DataMenuItem();
      newItem.Text = dr["Name"].ToString().Trim();
      newItem.Key = dr["ID"].ToString().Trim();
      WebDataMenuMain.Items.Add(newItem);
    }
