Setting document mode of IE based upon browser mode at run time (C hash) 1

Recently I was working on a project that required me to force the user into IE9 document mode, but ONLY if they were using IE9 compatibility view (CV)  or  IE 10 mode.

The main elements that we need to look at are the Version token and the Trident token. Below are the tokens that you will find in each browser:

                                                          VERSION                   TRIDENT

IE9 StandardMSIE 9.0Trident/5.0
IE9 CVMSIE 7.0Trident/5.0
IE8 StandardMSIE 8.0Trident/4.0
IE8 CVMSIE 7.0Trident/4.0
IE7MSIE 7.0No Trident token
IE6MSIE 6.0No Trident token

As you can see, each browser has a unique combination of these two tokens. We can use this knowledge to now create a function that will tell us what browser mode is in use. My function is shown below:


private string GetIEBrowserMode()

{

string mode = "";

string userAgent = Request.UserAgent; //entire UA string

string browser
