Force IE10 to run in IE10 Compatibility View

Question

I have an app that is broke in IE10 but runs fine in IE10 Compatibility View  A quick google results in the    lt meta http-equiv  X-UA-Compatible  content  IE 8  gt   lt  -- plus variations such as emulate  quirks  7  8  9 --- gt    tag  Some MS documentation on the tag is here  If you press F12 you can see that it changes the document mode  I need it to change the Browser Mode to Internet Explorer 10 Compatibility View  Is there any tag that will do this     UPDATE I need to mention that I have tried all of the following doctypes and none of them work  I think the only way to get this to work in IE10 is to use Compatibility View     lt  --      lt  DOCTYPE html gt       lt  DOCTYPE HTML PUBLIC  -  W3C  DTD HTML 4 01  EN   http   www w3 org TR html4 strict dtd  gt       lt  DOCTYPE HTML PUBLIC  -  W3C  DTD HTML 4 01 Transitional  EN   http   www w3 org TR html4 loose dtd  gt       lt  DOCTYPE HTML PUBLIC  -  W3C  DTD HTML 4 0 Transitional  EN   http   www w3 org TR html4 loose dtd  gt       lt  DOCTYPE HTML PUBLIC  -  W3C  DTD HTML 4 01 Frameset  EN   http   www w3 org TR html4 frameset dtd  gt       lt  DOCTYPE html PUBLIC  -  W3C  DTD XHTML 1 0 Strict  EN   http   www w3 org TR xhtml1 DTD xhtml1-strict dtd  gt       lt  DOCTYPE html PUBLIC  -  W3C  DTD XHTML 1 0 Transitional  EN   http   www w3 org TR xhtml1 DTD xhtml1-transitional dtd  gt       lt  DOCTYPE html PUBLIC  -  W3C  DTD XHTML 1 0 Frameset  EN   http   www w3 org TR xhtml1 DTD xhtml1-frameset dtd  gt      TRIED NO DOCTYPE AT ALL TOO -- gt

While you should fix your site so it works without Compatibility View  try putting the X-UA-Compatible meta tag as the very first thing after the opening  lt head gt   before the title

You can try     lt meta http-equiv  X-UA-Compatible  content  IE EmulateIE8   gt    Just like you tried before  but caution   It seems like the X-UA-Compatible tag has to be the first tag in the   lt  head   section  If this conclusion is correct  then I believe it is undocumented in Microsoft   s blogs msdn  and if it is documented  then it isn   t sticking out well enough from the docs   Ensuring that this was the first meta tag in the  forced IE9 to switch to IE8 mode successfully

I had the exact same problem  this -  meta http-equiv  X-UA-Compatible  content  IE 7    works great in IE8 and IE9  but not in IE10  There is a bug in the server browser definition files that shipped with  NET 2 0 and  NET 4  namely that they contain definitions for a certain range of browser versions  But the versions for some browsers  like IE 10  aren t within those ranges any more  Therefore  ASP NET sees them as unknown browsers and defaults to a down-level definition  which has certain inconveniences  like that it does not support features like JavaScript   My thanks to Scott Hanselman for this fix   Here is the link -  http   www hanselman com blog BugAndFixASPNETFailsToDetectIE10CausingDoPostBackIsUndefinedJavaScriptErrorOrMaintainFF5ScrollbarPosition aspx  This MS KP fix just adds missing files to the asp net on your server  I installed it and rebooted my server and it now works perfectly  I would have thought that MS would have given this fix a wider distribution   Rick

The X-UA-Compatible meta element only changes the Document mode  not the Browser mode  The Browser mode is chosen before the page is requested  so there is no way to include any markup  JavaScript or such to change this  While the Document mode falls back to older standards and quirks modes of the rendering engine  the Browser mode just changes things like how the browser identifies  such as the User Agent string   If you   d like to change the Browser mode for all users  rather than changing it manually in the tools or through the settings   the only way  AFAICT  is to get your site added to Microsoft   s Copat View List  This is maintained by Microsoft to apply overrides to sites which break  There is information on how to remove your site from the compat view list  but none I can find to request that you re added   The preferred method however is to try to fix any issues on the site first  as when you don   t run using the latest document and browser mode you can not take advantage of improvements in the browser  such as increased performance

I had the same problem   The problem is a bug in MSIE 10  so telling people to fix their issues isn t helpful   Neither is telling visitors to your site to add your site to compatibility view  bleh   In my case  the problem was that the following code displayed no text   document write    lt P gt      document write   Blah  blah  blah        document write    lt  P gt       After much trial and error  I determined that removing the  lt P gt  and  lt  P gt  tags caused the text to appear properly on the page  thus  the problem IS with document mode rather than browser mode  at least in my case     Removing the  lt P gt  tags when userAgent is MSIE is not a  fix  I want to put into my pages   The solution  as others have said  is    lt  DOCTYPE HTML whatever doctype you re using     gt    lt HTML gt    lt HEAD gt     lt meta http-equiv  X-UA-Compatible  content  IE EmulateIE8  gt     lt TITLE gt Blah      Yes  the meta tag has to be the FIRST tag after HEAD

If you want to set the compatibility mode in the browser itself and not in the html do the following   Open IE 10 Press the ALT Key to bring up the IE Menubar Click on the Tools menu Click on compatibility view setting  Clicks check the box  display all the websites in compatibility view  or Add only the desired websites to the compatibility view   As shown in the image below  The website should then open up with IE 10 Compatibility view
