1. Check the Compatibility mode settings -> hit Alt -> expand Tools menu -> select Compatibility View Settings. They should be as in the screenshot below:
alert(document.documentMode);
There are several ways to achieve that:
from the Compatibility View Settings menu, unselect the "Display intranet sites in Compatibility View" checkbox
speak with your local administrators so they enforce this checkbox rule as a group policy
add an X-UA Compatible meta tag such as this one to your page:
<
head
id
=
"Head1"
runat
"server"
>
title
></
meta
http-equiv
"X-UA-Compatible"
content
"IE=edge"
/>
system.webServer
httpProtocol
customHeaders
add
name
value
</
