Repeater嵌套Repeater的结构：一般写过的都能看懂吧

private void RpTypeBind()

    {

        //GetQuestionTypeAndCount() 返回一个datatable

        this.rptypelist.DataSource = LiftQuestionCtr.GetQuestionTypeAndCount();

        this.rptypelist.DataBind();

    }

    protected void rptypelist_ItemDataBound(object sender, RepeaterItemEventArgs e)

    {

        //判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，

        //HeaderTemplate，，ItemTemplate，SeparatorTemplate）

        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

        {

            Repeater rep = e.Item.FindControl("rpquestionlist") as Repeater;//找到里层的repeater对象

            DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项

            int typeid = Convert.ToInt32(rowv["qtid"]); //获取填充子类的id

            rep.DataSource = LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid, 2);

            rep.DataBind();

        }

    }

<table border="0" cellpadding="0" cellspacing="0" style="margin-bottom: 5px" width="100%">

    <asp:Repeater runat="server" ID="rptypelist" OnItemDataBound="rptypelist_ItemDataBound">

        <ItemTemplate>

            <tr>

                <td class="fb">

                      <a href="Lists.aspx?Qtid=<%#Eval("qtid") %>"><%#Eval("qtypename") %></a> <span id="askCount_15"

                        class="date2">[<%#Eval("typecount")%>]</span>

                </td>

            </tr>

            <tr>

                <td>

                    <div id="askTop2_15" class="ask_list">
