In Windows Forms Applications Im using the following Code to scroll the Page inside a Webbrowser:

 HtmlDocument doc = webBrowser.Document;
 mshtml.IHTMLDocument2 htmldoc = (mshtml.IHTMLDocument2)doc.DomDocument;
 htmldoc.parentWindow.scrollBy(265, 20);

Does anyone know how to do the same in an WPF Application (without using WindowsFormsHost)?

If you're using System.Windows.Controls.WebBrowser class take a look at the Document property. You should be able to cast it to mshtml.HTMLDocument or mshtml.IHTMLDocument2 and code

mshtml.HTMLDocument htmlDoc = webBrowser.Document as mshtml.HTMLDocument;
if (htmlDoc != null) htmlDoc.parentWindow.scrollBy(265, 20);

should be working fine for you.

hope this helps, regards

you should do it easily :

    private void WebBrowser_LoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e)
    {

        ((WebBrowser)sender).InvokeScript("eval", "$( document ).scrollTop( 1700 );");
    }

The Javascript:

window.onload=toBottom;

function toBottom() { alert("Scrolling to bottom ..."); window.scrollTo(0, document.body.scrollHeight); }

The HTML:

> <html>
>     <head>
>         <script src="testme.js" language="javascript" type="text/javascript"></script>
>     </head>
>     <body>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>           
>     </body>
> </html>
