I have found the source of my issue. Microsoft released a security update for IE11 on 8 Jul 14 which has a bug affecting the download. See http://www.infralution.com/phpBB2/viewtopic.php?t=2834 for more information. I have confirmed that versions of IE11 without this update work without any problem.

Thanks for the Replay. i found that IE 11 is not working for pdf downloading. also found that it is working if the file size is less that 500Kb(not exactly) but not for more than 1 Mb for surely.

Hi.. This will work well with IE9 and BELOW Versions. This Code does not work with IE10 and versions above it. Reference- http://forums.asp.net/t/1962499.aspx?Internet+Explorer+11+and+Content+Type+PDF
