问题描述

我目前具有单选按钮和分组的问题。我有一个Repeater控件中的一个ASP单选按钮。我有组名称属性设置为客户。页面加载时，单选按钮不进行分组。代替的id字段被设置为组名，它是设置的单选按钮的值字段。我知道，我已经尝试设置单选按钮一个中继器控制之外，并有同样的问题。这到底是怎么回事呢？

解决方案

我终于通过创建一个普通的单选按钮，使用服务器端的eval设定值解决此得到。

 ＆LT;输入类型=电台NAME =radCustomer值='＆LT;％＃的eval（CUSTOMERNUMBER）％＆GT;' /＆GT;

现在，当应用程序执行回发，我检查的Request.Form [radCustomer]的值。这完美的作品。

I am currently having an issue with radio buttons and grouping. I have an asp radio button within a repeater control. I have the group name attribute set to "Customer". When the page loads, the radio buttons are not grouped. Instead of the id fields being set to the group name, it is setting the value fields of the radio buttons. I know that I have tried setting radio buttons up outside of a repeater control and have had the same issue. What is going on here?

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>

output html

解决方案

I finally got around this by creating a plain radio button and setting the value using an server-side eval.

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

Now when the application performs a postback, I check for the value of Request.Form["radCustomer"]. This works flawlessly.
