Older versions of IE used the Version value, while newer The sensible method is reading the value from the registry asĮverything else we are doing in this article involves the There are various ways of getting the installed IE version, but The user's computer and set the emulation version to match,įirst we need a way of detecting the IE version. Default value for applications hosting the WebBrowser Control.Īs it makes more sense to detect the version of IE installed on Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Webpages are displayed in IE8 Standards mode, regardless of the !DOCTYPE directive. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. Webpages are displayed in IE10 Standards mode, regardless of the !DOCTYPE directive. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Webpages are displayed in IE11 edge mode, regardless of the !DOCTYPE directive. The documentation doesn't mention if this is still the case regarding IE11 so I'm not sure on the behaviour in that regard. TheĮxception to this dual behaviour is version 7 which is as is.Īccording to the documentation the IE8 (8000) and IE9 (9000) modes will switch to IE10 (10000) mode if installed. In one of two ways - either by forcing a standards mode, orĪllowing !DOCTYPE directives to control the mode. Possible to emulate all "recent" versions of Internet Explorer The table below ( source) lists the currently supportedĮmulation versions at the time of writing. Setting some registry values and other caveats, but it is still It's notĪs simple as setting some properties on a control as it involves Rather fortunately however, Microsoft provide the ability toĬonfigure the emulation mode your application will use. Not so good as more and more sites use HTML5 and Internet Explorer 7 - or enabling Compatibility Mode in a modern Me is that by default it is essentially an embedded version of One of the things that occasionally frustrates The WebBrowser control annoys me in myriad ways, but it does Unless an application makes heavy use of HTML interfaces Shipping additional multi-MB dependencies doesn't make sense I'm aware other embeddable browsers exist, but the idea of Want to display real pages from the internet - in which case I'm However, I need a more complex layout, JavaScript or I might Might use a component such as HtmlRenderer. Just to display some simple layout with basic interactions, I So it sounds like the "programmatic" solution is to write a key in the registry saying you want IE8 Standards mode for WebBrowser controls in your specific application.Occasionally I need to embed HTML in my applications. Here I should note that the comments on the page say the above is incorrect, and that " IE8 renders pages running within instances of the WebBrowser control in IE7 Strict Mode OR Quirks mode by default, depending on the page's doctype."
