前台页面部分：

<asp:Repeater id="rptCategories" runat="server"> 

<HeaderTemplate> 

    <table width="100%" border="0" cellspacing="0" cellpadding="0"> 

</HeaderTemplate> 

<ItemTemplate> 

    <!--分类名称--> 

    <tr><th><%# DataBinder.Eval(Container.DataItem, "TypeName") %></th></tr> 

    <!--分类下的产品--> 

    <asp:Repeater id="rptProduct" runat="server"> 

      <ItemTemplate> 

        <tr><td><a href='ProductInfo.aspx?Id=<%# DataBinder.Eval(Container.DataItem, "ID") %>'><%# DataBinder.Eval(Container.DataItem, "ProductName") %></a></td></tr> 

      </ItemTemplate> 

    </asp:Repeater> 

</ItemTemplate> 

<FooterTemplate> 

    </table> 

</FooterTemplate> 

</asp:Repeater> 

后台代码部分（部分代码）：

//在绑定分类品名时,绑定分类下的产品 

private void rptCategories_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) 

{ 

    BLL.Products products =new BLL.Products(); 

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

    { 

        Repeater rptProduct = (Repeater) e.Item.FindControl("rptProduct"); 

        //找到分类Repeater关联的数据项 

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

        //提取分类ID 

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

        //根据分类ID查询该分类下的产品，并绑定产品Repeater 

        rptProduct.DataSource = products.GetProductsByCategorieId(CategorieId); 

        rptProduct.DataBind(); 

    } 

} 

另一种方法： 前台：

<!-- start parent repeater -->

<asp:repeater id="parentRepeater" runat="server">

   <itemtemplate>

      <b><%# DataBinder.Eval(Container.DataItem,"au_id") %></b><br>

      <!-- start child repeater -->

      <asp:repeater id="childRepeater" datasource='<%# ((DataRowView)Container.DataItem)

      .Row.GetChildRows("myrelation") %>' runat="server">

         <itemtemplate>

            <%# DataBinder.Eval(Container.DataItem, "[\"title_id\"]")%><br>

         </itemtemplate>

      </asp:repeater>

      <!-- end child repeater -->

   </itemtemplate>

</asp:repeater>

<!-- end parent repeater -->

后台：

public partial class NestedRepeater : System.Web.UI.Page

{

    protected System.Web.UI.WebControls.Repeater childRepeater;//parentRepeater;

    public NestedRepeater()

    {

        Page.Init += new System.EventHandler(Page_Init);

    }

    public void Page_Load(object sender, EventArgs e)

    {

        //Create the connection and DataAdapter for the Authors table.

        SqlConnection cnn = new SqlConnection("server=.;database=pubs; user id=sa;pwd=;");

        SqlDataAdapter cmd1 = new SqlDataAdapter("select * from authors", cnn);

        //Create and fill the DataSet.

        DataSet ds = new DataSet();

        cmd1.Fill(ds, "authors");

        //Create a second DataAdapter for the Titles table.

        SqlDataAdapter cmd2 = new SqlDataAdapter("select * from titleauthor", cnn);

        cmd2.Fill(ds, "titles");

        //Create the relation bewtween the Authors and Titles tables.

        ds.Relations.Add("myrelation",

        ds.Tables["authors"].Columns["au_id"],

        ds.Tables["titles"].Columns["au_id"]);

        //Bind the Authors table to the parent Repeater control, and call DataBind.

        parentRepeater.DataSource = ds.Tables["authors"];

        Page.DataBind();

        //Close the connection.

        cnn.Close();//51aspx.com

    }

    private void Page_Init(object sender, EventArgs e)

    {

        InitializeComponent();

    }

    private void InitializeComponent()

    {

        this.Load += new System.EventHandler(this.Page_Load);

    }

}
