How to do a ASP.NET MVC Ajax form post with multipart/form-data?

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

<form enctype="multipart/form-data" method="post" action='<%= Url.Action("Post","Entries",new {id=ViewData.Model.MemberDetermination.DeterminationMemberID}) %>'>

How would I write this to do an ASP.NET MVC Ajax form post instead?

  1. You can use some additional uploaders (e.g. jQuery multiple file uploader) (I prefer this way and I prefer not to use MS Ajax)
  2. Use:

    AjaxHelper.BeginForm("Post", "Entries", new {id=ViewData.Model.MemberDetermination.DeterminationMemberID}, new AjaxOptions(){/*some options*/}, new {enctype="multipart/form-data"})

But in second case I'm not sure that it will work.
