.net Repeater嵌套的数据绑定问题

<asp:Repeater ID="Repeater3" runat="server" OnItemDataBound="Repeater3_ItemDataBound">
        <ItemTemplate>

              bind(Data)//绑定的数据

        <asp:Repeater ID="Repeater4" runat="server">
             <ItemTemplate>

             bind(Data)//绑定的数据

             </ItemTemplate>
       </asp:Repeater>

       </ItemTemplate>
 </asp:Repeater>

后台Repeater4的绑定

?

/// <summary>

///数据绑定

///绑定回复

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

protected void Repeater3_ItemDataBound(object sender, RepeaterItemEventArgs e)

{

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

    {

        Repeater rpt1 = e.Item.FindControl("Repeater4") as Repeater;

        if (rpt1 != null)

        {

            Repeater rep = (Repeater)e.Item.FindControl("Repeater4");

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

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

            StringBuilder sb = new StringBuilder("select 语句 ");

            sb.Append(" where 条件(用到typeid )“);

            DataSet ds = Maticsoft.DBUtility.DbHelperSQL.Query(sb.ToString());

            rep.DataSource = ds;

            rep.DataBind();

        }

    }
