Refer my Tip/Article and just modify the code as below

ASP.NET Export Excel - Javascript event after download[^]

var loop = setInterval(function () {
         if (IsCookieValid()) {
             document.getElementById('imgloadinggif').style.display =  'none'; clearInterval(loop)
             // your code here..
             window.location.reload(); // reload the page
         }

     }, timeInterval);

When the user requests the page that downloads the file you can only send one response, and that response is the file stream for the client to download. The download itself is handled by the user's browser and you don't know if the file has been downloaded or not. Add to that if you want to do a redirect that is also a response and as above you can only send one response...a download or a redirect, you can't do both.

So basically you just can't do this.
