internet explorer - How to disable Compatibility View in IE

Question

I am wondering how do you stop people who are using IE 8 from going to Compatibility mode?

<meta http-equiv="X-UA-Compatible" content="IE=8" />

I found this tag and I think this forces people to stay in IE-8 mode but I am not too sure and can't check as I have IE 9.

If people are in IE 9 mode I force them to not go into IE 8 or IE 7 Compatibility mode?

I tried to put the above line in my code and went to IE 9 -> Tools -> Compatibility View(Grayed Out)

but "Compatibility View Settings" was not grayed out and it seems you could add the site through there.

So should that not disable?

Answer 1

All you need is to force disable C.M. in IE - Just paste This code (in IE9 and under c.m. will be disabled):

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7; IE=EDGE" />
