IE11 - Unable to get property 'PageRequestManager' of undefined or null reference

I have a asp.net web page with radgrid and radajaxmanager are used in it.

It works as expected on all browsers other than IE11

When I click on button I got this error on my Console.

Unable to get property 'PageRequestManager' of undefined or null reference

Any thoughts would be highly appreciated.

You can also check out this answer for more details or a post by Scott Hanselman detailing the problem. Core of the problem is outdated browser detection files on the server such that IE11 is an unknown browser (and therefore lacking Javascript support according to the server).
