I have Windows server 2016 and IIS 10 and IE 11.

When i moved the code from Windows server 2008 to 2016, "Unable to get property 'detachEvent' of undefined or null reference" error is comming instead of populating webgrid data.

internet explorer debugger found the attached bug.

Its working fine on windows server 2008 using IE11.

but its giving attached error when we moved to new WIN server 2016 R2 and using IE11

i even tried including metatag on page and in web.config but no effect.

<meta http-equiv="X-UA-Compatible" content="IE=5" />

Please give us solution. find the attached the issue.

Code is developed to target older version of HTML, i have seen kind of issue has been fixed under ASPNET-190. can you please let me know if this the same issue we are facing for webgrid in IE11 on win server 2016.
