[WPF] Alternative to the WebBrowser control?

[sathenzar]

Hey guys, is there another control in WPF like the WebBrowser control? I'd rather not use a WindowsFormHost if I can help it. But I can't find one so far.

Are you looking to display the web content direct to the user, or to process the returned HTML response within your own code? If so I've used Net.HttpWebRequest to some good effect, including navigating a website, posting data and obtaining the response data I needed. If you're interested I could post some code.

yeah pretty much do the same exact thing like be able to retrieve the html page, manipulate it and be able to make calls between the app and the web page.

Ok well here is a bit of code from an app I'm developing right now that communicates via http/html with another website to retrieve data, it includes logging on via a form based logon system. Its not totally finished, its error checking is quite poor.... but the main thing is it works and you can build on it. Let me know how you get on, and if you find it useful.
