目前想到的方法，请参考

HTML code


<asp:Repeater ID="Repeater1" runat="server"> 
     <ItemTemplate> 
        OrderID: <%# Eval("OrderID")%>
        CustomerID : 
         <asp:Label ID="Label1" runat="server" Text='<%#Eval("CustomerID")%>'></asp:Label> <br />
        <asp:Repeater ID="Repeater2" runat="server" DataSource='<%# GetOrderDetails(Convert.ToInt32(Eval("OrderID"))) %>'> 
            <ItemTemplate>  
                &nbsp;&nbsp;
                子容器得到CustomerID : <%# ((Label)((RepeaterItem)((Repeater)(((RepeaterItem)Container).NamingContainer)).NamingContainer).FindControl("Label1")).Text %> 
                UnitPrice: <%#Eval("UnitPrice")%> <br />
            </ItemTemplate> 
        </asp:Repeater> 
        <br />                 
     </ItemTemplate> 
</asp:Repeater>

C# code


private void BindRepeater()
{
    SqlConnection cn = new SqlConnection(@"server=.\SQLExpress;uid=sa;pwd=;database=Northwind");
    SqlDataAdapter da = new SqlDataAdapter("select top 10 orderid, CustomerID, OrderDate from Orders", cn);
    DataSet ds = new DataSet();
    cn.Open();
    da.Fill(ds);
    cn.Close();
    Repeater1.DataSource = ds.Tables[0].DefaultView;
    Repeater1.DataBind();
}

protected DataTable GetOrderDetails(int orderID)
{
    SqlConnection cn = new SqlConnection(@"server=.\SQLExpress;uid=sa;pwd=;database=Northwind");
    SqlDataAdapter da = new SqlDataAdapter("select ProductID, UnitPrice from [Order Details] where orderid = @orderid", cn);
    da.SelectCommand.Parameters.AddWithValue("@orderid", orderID);
    DataSet ds = new DataSet();
    cn.Open();
    da.Fill(ds);
    cn.Close();
    return ds.Tables[0];
}

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindRepeater();
    }
}
