Progress when requesting to download a file with Fileresult

How can I display a progressibar while the server processes a Fileresult return?

I tried to perform the operation with Ajax, but it is not possible to download a file via ajax without redirecting it (using a window.location.href) for the action that returns Fileresult.

c# asp.net-mvc

Hello. I believe that asynchronously it would solve.

  1. Open a thread on the server and download the file to a temporary directory
  2. Download by controlling progress. See: http://devtoolshed.com/content/c-download-file-progress-bar
  3. In the client, ask the server what the progress percentage is and update your progress.
  4. Download the file now!

Abs.
