You cant call a file download on a ajax query because the browser wont trigger the file download. dont use an ajax call to your controller method, you can use like
window.open("url/Exporttoexcel?id=");
with adding paramaters.
The problem may be that you cant actually download via an ajax call. If you look at this: jQuery plugin for requesting ajax like file downloads.
This will help you!
Also you can use
window.location.href = "controllerName/GridExportToExcel?id="
