Return File from MVC controller using http get

Question

I am calling the MVC controller which returns a FileResult back using XMLHttpRequest. For some reason i don't get a prompt for download/save the file , i do get the file content as the response from the get request(Checked in network tab).

I don't have the url of the file only have contentbytes, so can't use window.location

Please help.

Do not use XMLHttpRequest to open file link, do

Javascript redirect

window.location = "http://www.yoururl.com";
open popup with that link

Without url, you can not call XMLHttpRequest. Put screenshot of your network tab

Before returning the file in your controller action, try to add a content-disposition header (directly as below, or using System.Net.Mime.ContentDisposition).

Response.AppendHeader("content-disposition", "inline; filename=" + fileName);

Also have a look at RFC 6266

On the client side, call the url that returns the attachment:

window.open('..../controller-name/action-that-returns-the-file');
