Is it possible to overlap WPF WebBrowser with other UIElement?

I want to put over WPF WebBrowser some UIElement (opacity = 0) ie and catch all click events via this overplaced UIElement.

Is it possible to do?

This code doesn't work...

<Canvas Name="cnsMain">
  <WebBrowser x:Name="MainBrowser" Visibility="Visible" Panel.ZIndex="0" />
  <Canvas Panel.ZIndex="100" Opacity="0.01"></Canvas>
</Canvas>

Thanks!

This can be done in .NET 4.5. It requires setting the following properties on your WebBrowser control before it is ever rendered:

IsRedirected = true
CompositionMode = System.Windows.Interop.CompositionMode.Full

This will enable hwnd redirection, allowing the normal top-level hwnd used for rendering to be redirected to a WPF surface that can play nice with other elements in your tree.

EDIT: It would seem this feature was yanked out of .NET 4.5 prior to release. My apologies if I gave anyone false hope. Thanks to @JoeDaley for pointing out my error.

No, the WPF Webbrowser is just the standard browser control in a WPF wrapper. It is not native WPF and therefore does not respect the ZOrder of WPF apps.

No, you can't do it with the WPF WebBrowser that originally ship with SDK. It always on top of other UIElement.

But I think it is possible with 3rd party control.

For detail take a look in this question I asked before.
