asp.net - asp.net单选按钮分组

Question

我目前在单选按钮和分组方面遇到问题。我在中继器控件中有一个ASP单选按钮。我将组名属性设置为“客户”。页面加载时，单选按钮未分组。不是将id字段设置为组名，而是设置单选按钮的value字段。我知道我已经尝试在中继器控件之外设置单选按钮，并且遇到了同样的问题。这里发生了什么？

aspx

<asp:Repeater ID="repCustomers" runat="server">
    <HeaderTemplate>
        <table class="tableDefault" cellpadding="0" cellspacing="0" border="0" style="width: 383px; border: 0px !important">
            <tr>
                <th>&nbsp;</th>
                <th>Cust. No.</th>
                <th>Cust. Name</th>
            </tr>
    </HeaderTemplate>
    <ItemTemplate>
            <tr>
                <td>
                    <asp:RadioButton ID="radCustomer" GroupName="Customer" runat="server" ValidationGroup="Customer" ToolTip='<%#Eval("CustomerNumber") %>' />
                </td>
                <td><%#Eval("CustomerNumber")%></td>
                <td><%#Eval("Name") %></td>
            </tr>
    </ItemTemplate>
    <FooterTemplate>
        </table>
    </FooterTemplate>
</asp:Repeater>

Answer 1

我终于通过创建一个普通的单选按钮并使用服务器端eval设置了值来解决了这个问题。

<input type="radio" name="radCustomer" value='<%#Eval("CustomerNumber") %>' />

现在，当应用程序执行回发时，我将检查Request.Form [“radCustomer”]的值。这完美无瑕。
