asp.net 单选按钮分组

asp.net radio button grouping(asp.net 单选按钮分组)

问题描述

我目前遇到单选按钮和分组问题.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.它不是将 id 字段设置为组名，而是设置单选按钮的值字段.我知道我曾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.这是怎么回事?

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>

推荐答案

我终于通过创建一个普通的单选按钮并使用服务器端 eval 设置值来解决这个问题.

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") %>' />

现在，当应用程序执行回发时，我检查 Request.Form["radCustomer"] 的值.这完美无缺.

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