想用repeater嵌套repeater做个2级菜单


我瞎写的代码

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" 
                 ConnectionString="<%$ ConnectionStrings:zidaiHaiyang %>" 
                 SelectCommand="SELECT * FROM [Region]"></asp:SqlDataSource>
</ul>
</div>

看了一些网上的代码，搞不懂，好像还要写后台？？？
<asp:SqlDataSource ID="SqlDataSourceQuyu" runat="server" 
                 ConnectionString="<%$ ConnectionStrings:zidaiHaiyang %>" 
                 SelectCommand="SELECT * FROM [Region]"></asp:SqlDataSource>
这些还是写到后台去吧，易于维护修改，也让前台代码看起来整洁一些

换个写法吧，<%# Eval("id")%>直接写成上一级查询ID的SQL语句试试，报错是因为页面的<asp:SqlDataSource>中不允许出现<%# Eval("id")%>

问题就是我不知到怎么换个写法。。。<%# Eval("id")%>这个换成啥？解决就结贴
直接写成上一级查询ID的SQL语句，where [RegionId] in (查询上一级ID)
[解决办法]
SelectCommand='<%# "SELECT [RegionId], [ProductName], [province] FROM [RegionProduct] where [RegionId] =" + Eval("id") %>'
