關於DataList的嵌套 和（ItemCommand）事件的問題

    找到嵌套的DataList（註：因為第一行為標題，所以第一次行迴圈找不到DataList 所以才要判斷if (DataListDepartment != null)）
  protected void score_ItemDataBound(object sender, DataListItemEventArgs e)
{
       DataList DataListDepartment = e.Item.FindControl("DataListDepartment") as DataList;
            if (DataListDepartment != null)
            {
                DataTable DepartmentSingalInformation = new DataTable();
                SqlDataAdapter sda = new SqlDataAdapter("Article_DepartmentSingalInformation", myConnection);
                sda.SelectCommand.CommandType = CommandType.StoredProcedure;
                sda.SelectCommand.Parameters.Add(new SqlParameter("@articleID", articleID));
                sda.SelectCommand.Parameters.Add(new SqlParameter("@CreateDepartment", Convert.ToInt32(DepartmentID.Text)));
                sda.Fill(DepartmentSingalInformation);
                DataListDepartment.DataSource = DepartmentSingalInformation;
                DataListDepartment.DataBind();
            }
}

另外在ItemCommand事件中 找到一行和gridview的區別是（GridViewRow WorkGuideGridViewRow = (GridViewRow)((Control)e.CommandSource).Parent.Parent）
        protected void score_ItemCommand(object source, DataListCommandEventArgs e)
        {
            DataListItem DataListItemRow = (DataListItem)((Control)e.CommandSource).Parent;
            Label DepartmentID = DataListItemRow.FindControl("DepartmentID") as Label;
            Label DepartmentName = DataListItemRow.FindControl("DepartmentName") as Label;
            if (e.CommandArgument == "MoreInformation")
            {
 
            }
        }
