A strongly typed RadioButtonList for ASP.NET MVC

There are many strongly typed controls in ASP.NET MVC. For example TextBoxFor. I really like using the strongly typed HTML helpers because you get much better information at compile time. Especially if you've turned on compile time view checking.

The one control that was missing, however is RadioButtonList. There is no "RadioButtonListFor" to be found. So I wrote my own.

This is what the code looks like in the aspx

<%= Html.RadioButtonListFor(m => m.GenderRadioButtonList)%>

Here's the code in the controller to check what the user has selected

public ActionResult Submit(HomePageViewModel viewModel)
{
  if (viewModel.GenderRadioButtonList.SelectedValue == HomePageViewModel.GenderType.Female)
  {
    // Do something
  }
  return View("Index", viewModel);
}

The code, plus a sample website using it, is in this zip file.

Additionally, at the risk of creating an infinite loop, here's a StackOverflow question that this post is an answer to. It's got some useful comments and more code.
