title: How to keep input type=file field value after failed validation in ASP.NET MVC?
body: <p>I've got a simple form in an MVC app I've made. It contains a file field so users can upload an image. It all works great.</p>
  
  <p>Problem is, if the form submit fails validation the content of the file field is lost (other fields remain populated, thx HtmlHelpers!). <strong>How do I keep the file field populated after a failed validation?</strong></p>
  
  <p>TIA!</p>
