So my question is, whether the WebBr

    A note about 64bit Windows which seems to trip up a few folks. If your app is running under 64bit Windows, you likely have to set the DWORD under [HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] instead.

    WebBrowser control will use whatever version of IE you have installed, but for compatibility reasons it will render pages in IE7 Standards mode by default.

    If you want to take advantage of new IE9 features, you should add the meta tag <meta http-equiv="X-UA-Compatible" content="IE=9" > inside the <head> tag of your HTML page.

    This meta tag must be added before any links to CSS, JavaScript files etc that are also in your <head> to work properly though (only other <meta> tags or the <title> tag can come before it).

    An alternative is to add a registry entry to:

    HKLM > SOFTWARE > Microsoft > Internet Explorer > Main > FeatureControl > FEATURE_BROWSER_EMULATION

    And in there add 'myApplicationName.exe' with value '9000' to force the WebBrowser control to display pages in IE9 mode. Though there are other values you can use too too, note that these docs aren't entirely accurate as it does not seem possible to get a page to render in IE 8 mode whatever value you use.

    Adding the registry key to the same path in HKCU instead of HKLM will also work - this is useful as writing to HKLM requires admin privileges where as HKCU does not.

    Just to be complete...

    For 32 bit OS you must add a registry entry to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

    *******OR*******

    For 64 bit OS you must add a registry entry to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

    This entry must be a DWORD, with the name being the name of your executable, that hosts the Webbrowser control; i.e.:

    myappname.exe (DON'T USE "Contoso.exe" as in the MSDN web page...it's just a placeholder name)

    Then give it a DWORD value, according to the table on:

    http://msdn.microsoft.com/en-us/library/ee330730(v=vs.85).aspx#browser_emulation

    I changed to 11001 decimal or 0x2AF9 hex --- (IE 11 EMULATION) since that isn't the DEFAULT value (if you have IE 11 installed -- or whatever version).

    That MSDN article contains notes on several other Registry changes that affects Internet Explorer web browser behavior.

    I totally agree with the solution provided, but I think a little clarification is important I think, might be necessary.

    For each process (read also: vshost.exe, yourWinformApplication.exe.svchost, or the name of your application.exe) that will need to add a DWORD with the value provided, in my case I leave 9000 (in decimal) in application name and running smoothly and error-free script.

    the most common mistake is to believe that it is necessary to add "contoso.exe" AS IS and think it all work!

    I came to this solution and it did not worked for me! Because I was using 64bit I had to replace the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

    Instead of the one that everyone talks about:

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]

    Regarding whitehawk's accepted answer. I am just trying to add a bit hands on experience. Was just trying to add a comments, but SO complains it's too long.

    Basically, without IE 9 installed, the registry switch FEATURE_BROWSER_EMULATION won't work AT ALL.

    For example, my own experience today I was trying to get the .net webcontrol to work with IE10 mode because one html I am trying to render won't work with .netControl under VS2012, and not even work when I load the html to IE8 directly, still css won't render properly(even after I say allow blocked content). But I have tested the same html ok with IE10 on a friend's win 8 machine. That's why I am trying to set the .net webControl to IE 10 mode but just keeps failing...

    Now I figured this is bcos my win 7 machine only have IE8 installed, so regardless which value I set to the FEATURE_BROWSER_EMULATION switch(value to IE9, IE10 IE11), it just won't work AT ALL !

    Then I downloaded and installed IE 10 on my win 7 machine. Still it won't work, then I added the FEATURE_BROWSER_EMULATION, it started working !

    Also I noticed regardless which value I set , even set it to value 0 by default, the webControl is still using IE 10 mode which still works for me.

    So to summarise, If you have IE X installed but you want your .Net webControl to work under IE (X+N) N>0 modo, TWO things you need to do:

    1. Go to MS website & download and install IE (X+N) on your machine, you will need to reboot after installation.

    2. apply whitehawk's answer.

    Basically: To control the value of this feature by using the registry, add the name of your executable file to the following setting and set the value to match the desired setting.

    HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
   SOFTWARE
      Microsoft
         Internet Explorer
            Main
               FeatureControl
                  FEATURE_BROWSER_EMULATION
                     contoso.exe = (DWORD) 00009000

    Windows Internet Explorer 8 and later. The FEATURE_BROWSER_EMULATION feature defines the default emulation mode for Internet Explorer and supports the following values.

    Value Description

    • 11001 (0x2AF9 Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the !DOCTYPE directive.

      11000 (0x2AF8) IE11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Default value for IE11.

      10001 (0x2711) Internet Explorer 10. Webpages are displayed in IE10 Standards mode, regardless of the !DOCTYPE directive.

      10000 (0x02710) Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. Default value for Internet Explorer 10.

      9999 (0x270F) Windows Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive.

      9000 (0x2328) Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9.

      Important In Internet Explorer 10, Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.

      8888 (0x22B8) Webpages are displayed in IE8 Standards mode, regardless of the !DOCTYPE directive.

      8000 (0x1F40) Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Default value for Internet Explorer 8 Important In Internet Explorer 10, Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.

      7000 (0x1B58) Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Default value for applications hosting the WebBrowser Control.
