遍历DataList控件找里面的ID找不到
不知道怎么写才能找到DataListItem 里面的ID，后来加个div元素也试也是找不到ID。不管服务端控件还是HTML元素都是找不到

C# code

   private void findDatalistControl()    {//这种方法item调试conut是0所以进不到循环里面        foreach (DataListItem item in DataListProduct.Items)        {            labProName = item.FindControl("labProName") as Label;        }//这种方法Controls调试conut也是0所以进不到循环里面        foreach (DataListItem item in DataListProduct.Controls)        {            labProName = item.FindControl("labProName") as Label;        }    }

HTML code

<div class="LiteralContent">        <asp:DataList ID="DataListProduct" runat="server"             >            <ItemTemplate>                <div id="a">                    <asp:ImageButton ID="imgbutProduct" runat="server" />aa                </div>                <div id="b">                    <asp:Label ID="labProName" runat="server" Text="Label">aaa</asp:Label>                </div>            </ItemTemplate>        </asp:DataList>    </div>

C# code

if (!Page.IsPostBack)            {                DataTable dt = new DataTable();                dt.Columns.AddRange(new DataColumn[] {                     new DataColumn("aa",typeof(string))                });                DataRow dr = dt.NewRow();                dr["aa"] = "guwei11";                dt.Rows.Add(dr);                dr = dt.NewRow();                dr["aa"] = "guwei22";                dt.Rows.Add(dr);                this.DataListProduct.DataSource = dt.DefaultView;                this.DataListProduct.DataBind();                            }
