WebBrowser Control IE8 Compatibility Mode On/Off Switch

Question

I am having a IE8 compatibility issue while using the WebBrowser control to navigate to a website. The strange thing is sometimes the website works, but more than likely it wont. I can refresh the page sometimes and it works as well.

Just going to the page in IE8 I experienced the same CSS rendering problems so I switched to compatibility mode and it refreshed and rendered correctly.

Is there a way to simulate this effect for the WebBrowser control. I want to be able to click a button and toggle the modes off and on like you can do in Internet Explorer.

Is this possible? If so, anyone know how?

Thanks

Answer 1

Would this post on IEBlog about WebBrowser rendering modes and IE8 help? Seems like you have to set the rendering mode specific to your application using a key in the registry.

Answer 2

I know the registry entry answer has been posted, so I thought I'd offer an alternative.

Do you own the site and have permissions for the server it runs on? If so, you can set the X-UA-Compatible header to be sent for every page on the site/server. See http://msdn.microsoft.com/en-us/library/cc288325(VS.85).aspx#Servers for information plus links for Apache/IIS7.
