MVC Progress Bar using http Post

I am using Microsoft MVC I have written a view that uploads files to the Amazon S3 API. I would like a progress bar in my view to show the progress of the processing of that action in my controller not the uploading of the file in particular.

I have tried a few JQUERY/AJAX uploaders but every time I loose the value of The HttpPostedFileBase and the value of the file is null.

I basically need to find a progress bar function that supports Post and multipart/form-data.

Code is below

ASPX

<%using (Html.BeginForm("Upload", "Tracks", FormMethod.Post, new { enctype = "multipart/form-data" }))
{%>
  <label for="BandName">Artist</label> 
       <%=Html.TextBox("Artists") %><%:Html.ValidationMessage("Artist","*")%>
        <div class="clearfix">
        </div>
        <label for="SongName">Song Title
        </label>
          <%=Html.TextBox("SongName") %><%:Html.ValidationMessage("SongName","*")%>
        <div class="clearfix">
        </div>
         <label for="SongName">Genre(s)
        </label>
          <%=Html.TextBox("Genres") %><%:Html.ValidationMessage("Genres","*")%>
        <div class="clearfix">
        </div>
        <label for="SongName">Mood(s)
        </label>
          <%=Html.TextBox("Moods") %><%:Html.ValidationMessage("Moods","*")%>
        <div class="clearfix">
        </div>

        <%:Html.Label("Country") %><%=Html.DropDownListFor(x => x.OrigCountryOptions,Model.OrigCountryOptions)%> <br /><br />
          <div class="clearfix">
        </div>
        <label for="FileName">File
        </label>
         <input type="file" name="SongFile" id="SongFile"/>
        <div class="clearfix">
        </div>


        <input type="submit" value="Submit" />
<%
   }
   %>

Controller action

  [Authorize]

        int data = SongFile.InputStream.Read(buf, 0, FileLen);



        if (FileLen > 100000000)
            ModelState.AddModelError("LargeFile", "File Size is limited to 10mb");
