We have to add below Meta Tag directly below inside Head Tag
Meta Tag will be placed at the top of every ASPX page.
Below is the code for Meta Tag:-
<meta http-equiv = "X-UA-Compatible" content = "IE=9">/Note:-
Above code will change compatibility mode for IE9 version.
Now,if we want to set a various number of compatibility modes in Internet Explorer then we have to specify the range in ascending order as Comma-separated list.Then IE will choose the highest of the specified modes that it can support.For Example:-
<meta http-equiv="X-UA-Compatible" content="IE=7,8,9">
