How to implement a file download in ASP.NET AJAX

I would like to use standard ASP.NET file download response, like in other Stack Overflow question.

Response.ContentType = \"application/octet-stream\";
Respo

You need to have this in a separate aspx that does not use ajax. Ajax is updating existing html markup on a page at the client side. What you try here is replace the responce content on the server side before sending anything to the client.

You could try this:

Have a page called Download.aspx that contains the transmit code you already have.

In your original page, you have a javascript call that calls the download page like this:

window.location.replace('Download.aspx');
