Elijah Manorwrote about the same trouble in ASP.NET MVC 1.0:
Elijah Manor在 ASP.NET MVC 1.0 中写到了同样的问题：
ASP.NET MVC Html.RadioButtonList Blues
ASP.NET MVC Html.RadioButtonList 蓝调
He decided to loop through his DataSource and create individual Html.RadioButton and Label combinations.
他决定遍历他的 DataSource 并创建单独的 Html.RadioButton 和 Label 组合。
<!-- After using and looking at the code for the Html.RadioButtonList in the ASP.NET MVC 1.0 RTM codebase, I'm not sure how it is supposed to be useful. It only outputs the actual input radio button and doesn't render any corresponding labels. To get around this I ended up writing a foreach creating individual Html.RadioButton and labels -->
<%
var radioButtonList = new SelectList(new List<ListItem> {
new ListItem { Text = "Current", Value="false", Selected=true },
new ListItem { Text = "Other", Value="true"}}, "Value", "Text", "false");
var htmlAttributes = new Dictionary<string, object> {
{ "class", "radioButtonList" },
{ "onclick", "if(eval(this.value)) { $('#tblDate').show('slow'); } else { $('#tblDate').hide('slow'); }" }
};
foreach (var radiobutton in radioButtonList) { %>
<%=Html.RadioButton("rblDate", radiobutton.Value, radiobutton.Selected, htmlAttributes)%>
<label><%=radiobutton.Text%></label>
<% } %>

It used to be in the previews but it was removed.
它曾经在预览中，但已被删除。
If you can't find it in the futures try something like this
如果您在期货中找不到它，请尝试这样的操作
<% foreach (Model model in Models))
{
%><%= String.Format("<input type=\"radio\" value=\"{0}\" name=\"{1}\" id=\"{2}\"><label for=\"{2}\">{3}</label>",
model.ID, "fieldName", model.modelID, model.Name) %><br />
<% } %>

If it were me I would just use a series of static HTML elements. I know some consider doing such a throwback to the ASP days, but it simplifies things IMO and ends up making for a more dependable and expectable [so I made up a word] GUI.
如果是我，我只会使用一系列静态 HTML 元素。我知道有些人考虑过回到 ASP 时代，但它简化了 IMO 并最终打造了一个更可靠和更可期待的 [所以我编了一个词] GUI。

Check out the MVC Futures DLL available in the MVC sourceon codeplex. In it there is an HtmlHelper extension to render RadioButton lists. It can automatically render a SelectList in the ViewData or you can pass it explicitly. Several overloads are available for different needs.
查看codeplex 上的MVC 源代码中提供的 MVC Futures DLL 。其中有一个 HtmlHelper 扩展来呈现 RadioButton 列表。它可以在 ViewData 中自动呈现 SelectList 或者您可以显式传递它。多种重载可用于满足不同的需求。
