HTML页面

 <asp:Repeater runat="server" ID="rptypelist" OnItemDataBound="rptypelist_ItemDataBound">
      <ItemTemplate>
          <div class="subnav_cp02">
              <span><%#Eval("ItemName") %></span>

     this.rptypelist.DataSource = Letao.BLL.ProductCategory.GetDataSet(0).Tables[0];

    //在绑定分类品名时,绑定分类下的产品

备注：绑定大类时返回的是表结构
