WebBrowser控件IE 10文档标准模式

Question

I have a Windows Form C# application which hosts a WebBrowserControl in it. Application's users will have IE 11 installed on their machine. I need to force them to use IE 10 documents standards mode. I know I can do that by using FEATURE_BROWSER_EMULATION as described in: http://msdn.microsoft.com/en-us/library/ee330730(v=vs.85).aspx#browser_emulation

The issue is that I am able to force the users to IE10 using 10001 and/or 10000 registry values. But, my documents mode is not setting properly. I need to set it to document standards mode.

I have checked and registry values are getting set correctly. I am not sure what can be done at this point. Does anyone have any suggestions ?

Thanks, Harit

Answer 1

You would want to use code 10001 to force IE 10 all the time regardless of the doctype.

Are you certain you are setting the Correct Reg Key value based on the system type? The key is in two different locations for a 32 or 64 bit system. Double check that and the 10001 code is used.

Other than that according to the documentation it should always no matter what show in IE 10 mode.

Next steps: :-) Are you using older or 3rd party controls that would force compatibility mode? Some do this with IE specific API's prior to IE8.

Are you using some browser specific CSS hacks? Those can throw the doctype off.

Are you able to control the doctype and set the doctype to html standards on the pages renderred in the control? If you use the standard IE 10 doctype like so and still getting compatibility mode?( )

Since it is a control I assume you have no conditional comments, those can throw it off too, so if you code does have IE conditional comments in them that can hose the doctype.

If so then something else is FORCING the browser into compatibility mode. I would start removing 3rd party controls, or CSS files, or even included Javascript files until you get the proper doctype and isolate the exact issue putting the doctype in the wrong mode.

You can test by rendering a straight html, with doctype set properly, sample page from your exe with no external links or 3rd party controls, just text on the page. Does that render properly?

Just some hints to isolate the offending thing.
