I did not read them but I think they proposed a workaround. http://geekswithblogs.net/GruffCode/archive/2010/10/28/detecting-the-file-download-dialog-in-the-browser.aspx Another possibility is: 1- Generate the file 2- Once it is ready trigger the download. I.e. poll the server to see if generation finished. Then use polling ajax request to trigger download. > The solutions that you have sent me the links to, are for problems relating > to the GUI not being responsive after the file has been downloaded.
