I have setup IE11 browser in compatibility mode through code. It's working fine but when a page has iframe the content inside the iframe coming in standard mode only. Is there any way to enforce iframe also in compatibility mode when main page is opening on the same?
Try adding this as the first line in the meta head section..
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
or
<meta http-equiv="X-UA-Compatibility" content="IE=5" />;
