How to implement file download with AJAX and MVC

Question

I would like to provide a file download operation by using the jQuery AJAX call with some params under MVC

Example

(javascript)
function DoDownload(start         


        

Answer 1

Your controller action method should return a FileResult instead of void. And there is no need to do this via AJAX - in fact, you don't want to do this with AJAX. You'll need the browser involved so it knows to provide a download dialog for the user.

I hope this helps.
