想用repeater嵌套repeater做个2级菜单
区域（东北，华北，西北）是一级菜单，省份（沈阳，广东）是二级菜单
区域表（ID，name） 省份表（区域ID外键，省份名）
Repeater1 把每个区域查询出来，Repeater2每个区域的ID 查询出相应的省份，

死的HTML 效果图


我瞎写的代码

<div class="menu">

<ul>

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSourceQuyu">

                <ItemTemplate>

                    <li><a class="hide" href="###"><%# Eval("region")%></a>

                        <ul>

                            <asp:Repeater ID="Repeater2" runat="server" DataSourceID="SqlDataSourceQuyu2">

                                <ItemTemplate>

                                    <li><a href="###"><%# Eval("province")%></a></li>

                                </ItemTemplate>

                            </asp:Repeater>

                            <asp:SqlDataSource ID="SqlDataSourceQuyu2" runat="server" 

                            ConnectionString="<%$ ConnectionStrings:zidaiHaiyang %>" 

                            SelectCommand='SELECT [RegionId], [ProductName], [province] FROM [RegionProduct] where [RegionId] =<%# Eval("id")%>' ></asp:SqlDataSource>

    //我想根据上一级的id查到此

                        </ul>

                    </li>

                </ItemTemplate>

             </asp:Repeater>

             <asp:SqlDataSource ID="SqlDataSourceQuyu" runat="server"
