ASP.net中的Repeater控制項嵌套

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound"> 

<HeaderTemplate><ul></HeaderTemplate> 

<ItemTemplate> 

<li><%# Eval("cate_name") %> 

    <asp:Repeater ID="Repeater2" runat="server"> 

    <HeaderTemplate><ul></HeaderTemplate> 

    <ItemTemplate> 

        <li><%# Eval("art_title") %></li> 

    </ItemTemplate> 

    <FooterTemplate></ul></FooterTemplate> 

    </asp:Repeater> 

</li> 

</ItemTemplate> 

<FooterTemplate></ul></FooterTemplate> 

</asp:Repeater> 

後端代碼：

protected void Page_Load(object sender, EventArgs e) 

{ 

    if(!IsPostBack) 

    { 

        using(SqlConnection conn= new SqlConnection()) 

        { 

            conn.ConnectionString = ConfigurationManager.ConnectionStrings["testdbConnectionString"].ConnectionString; 

            conn.Open(); 

            using(SqlDataAdapter da = new SqlDataAdapter("select * from category",conn)) 

            { 

                DataSet ds = new DataSet(); 

                da.Fill(ds); 

                Repeater1.DataSource = ds; 

                Repeater1.DataBind(); 

            } 

        } 

    } 

} 

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) 

{ 

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

    { 

        Repeater rep = e.Item.FindControl("Repeater2") as Repeater; 

        DataRowView rowv = (DataRowView)e.Item.DataItem; 

        int cate_id = Convert.ToInt32(rowv["cate_id"]); 

        using (SqlConnection conn = new SqlConnection()) 

        { 

            conn.ConnectionString = ConfigurationManager.ConnectionStrings["testdbConnectionString"].ConnectionString; 

            conn.Open(); 

            using (SqlDataAdapter da = new SqlDataAdapter("select * from article where owner_id=" + cate_id, conn)) 

            { 

                DataSet ds = new DataSet(); 

                da.Fill(ds); 

                rep.DataSource = ds; 

                rep.DataBind(); 

            } 

        } 

    } 

} 

兩個Repeater的嵌套，通過ID關聯嵌套部分，輸出如下:
