How to change browser mode in IE9 permanently?
Solution 1:
You can solve this issue with <meta x-ua-compatible />
element and providing it the ie7 variable.
Another alternative is to change the document mode using the documentMode
property.

Solution 2:
I don't think you can really affect the browser mode setting; this seems to be a developer debugging feature. If a user is running IE9, the browser mode will be IE9 or IE9 Compatibility View. You can affect the compatibility view setting by using the X-UA-Compatible <meta>
tag or HTTP header (though, watch out for the Tools -> Compatibility View settings - > "Display Intranet sites in Compatibility View" setting).
