WPF WebBrowser control issues with AllowsTransparency = True
7.July.08 – 15:55I recently played around with the new Webbrowser control delivered with the SP1 update of .NET 3.5 .
But when i tried to use it in a WPF Window that has its WindowStyle set to None and AllowsTransparency to True (due to some custom window drawing), i noticed that the Webbrowser control disappeared.
The Webbrowser control is just a native Win32 Hwnd that gets hosted inside some WPF content area. But it’s quite annoying that the Transparency stuff gets pass on to it.
I wonder how i could circumvent this limitation as i don’t need transparency in the webbrowser control itself. Its just to get some homegrown, fancy-looking window style.
I’m looking forward to see this fixed by Microsoft in some future release.

Hello, did you ever find a work around for this? I’m interested in doing something similar.

hi chris,
it’s bad that there is no pure .net solution for this limitation (yet)! i wrote a workaround with win32 native calls to draw the stuff myself. Jan-Cornelius Molnar has a short blogpost
on this topic which gave me the initial idea to just do it myself. Although it’s VB.NET it may be a good starting point.
regards
j.

It’s unlikely there will be a general solution for the child window composition problem anytime soon. Here is one possible workaround now: http://blogs.msdn.com/changov/archive/2009/01/19/webbrowser-control-on-transparent-wpf-window.aspx.
