I am using the code below to hide the scroll bars on the WebBrowser control and it does not seem to be working as I might expect.

<WebBrowser x:Name="webPage" ScrollViewer.CanContentScroll="False" ScrollViewer.VerticalScrollBarVisibility="Hidden" ScrollViewer.HorizontalScrollBarVisibility="Hidden"/>

Open in new window


Can someone point out what I may be missing here?

WPF webbrwoser is not really WPF but the activeX webbrowser and therefore this is not going to work. Even if you put it inside a scrollviewer its probably not going to work (speculating here). One thing you can do is to execute a JS script to hide the scrollbars in the ONLoadcompleted event. There are several examples on net for doing this.

WebBrowser is a listed control for WPF as to its source, I can't comment.  However it is the suppression of scroll bars I seek not their addition.  I hope that clarifies what I am looking to do.

After some cobbling together of code from several sources it seem the issue is not with the control ion terms of control scrollbars.  The issue is that some web pages have scroll bars and they are not in the control of the hosting control.

I Added this library Microsoft.mshtml and this code.

        private void webPage_LoadCompleted(object sender, NavigationEventArgs e)
        {
            mshtml.IHTMLDocument2 documentText = (IHTMLDocument2)webPage.Document; 
            documentText.body.parentElement.style.overflow = "hidden"; 
        }

I have solved the problem here.  The test site I used was http://www.bbc.co.uk/news but any similar will be fine.

Oh man this is exactly what I was referring to "execute code in loadCompleted to turn off scrollbars." I'm glad you found the exact code.

Whilst the proposed answer was not entirely appropriate in technology use it did enable me to re-examine the problem from a different angle.
