The simplest way to do this is to return a view from your controller after the post that has an onload script.

On the new view, put the following javascript:

In the controller set the following after file uploaded

ViewData["FileUploaded"] = "true";

Then in the view set

<% if (!String.IsnullOrEmpty(ViewData["FileUploaded"]) && ViewData["FileUploaded"] == "true") { %>
     <script type="text/javascript">
        $(document).ready(function() {
            SayFinished();
        });

        function SayFinished() {
            alert('Finished');
        }
     </script>
<%} %>
