title: How to do a ASP.NET MVC Ajax form post with multipart/form-data?
body: <p>I am working on a ASP.NET MVC web site which has a form that allows for the upload of files using the multipart/form data enctype option on the form tag like so</p>
  
  <pre><code>&lt;form enctype="multipart/form-data" method="post" action='&lt;%= Url.Action("Post","Entries",new {id=ViewData.Model.MemberDetermination.DeterminationMemberID})  %&gt;'&gt;
  </code></pre>
