title: Adding a class to an Ajax.BeginForm Call in Razor View Model
body: <p>I have a the following code </p>
  
  <pre><code>@using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "update_panel", Url = "/Part/SearchPart" }))
          {
              &lt;input type="text" placeholder="Search Parts"/&gt;
              &lt;input type="submit" value="Search"/&gt;
          }
  </code></pre>
  
  <p>it outputs the following HTML</p>
  
  <pre><code>&lt;form action="/Part" data-ajax="true" data-ajax-mode="replace" data-ajax-update="#update_panel" data-ajax-url="/Part/SearchPart" id="form0" method="post"&gt;                        
      &lt;input type="text" placeholder="Search Parts"/&gt;
          &lt;input type="submit" value="Search"/&gt;
