title: When using .net MVC RadioButtonFor(), how do you group so only one selection can be made?
body: <p>This one has me stumped, I have a strongly typed view that has this loop to generate radiobuttons:</p>
  
  <pre><code>&lt;% foreach (QuestionAnswer qa in Model.QuestionAnswers)
     { %&gt;
      &lt;%= Html.RadioButtonFor(model =&gt; model.QuestionAnswers[(int)qa.QuestionID - 1].AnswerValue, "Checked" ) %&gt;
      &lt;%= Html.Encode(qa.OptionValue) %&gt;
  &lt;% } %&gt;
  </code></pre>
  
  <p>It renders fine, but since the names are not the same, you can select more than 1 radiobutton.  How can I group them so only 1 radiobutton can be selected?</p>
  
  <p>Any help would be appreciated!</p>
