Displaying wpf content over/outside main window bounds [closed]

Answer 1

Contents of window will always get clipped. So basically there is only one way to go here. You could get the desired effect by creating a new transparent window for your floating content and then manualy set and update the position of floating content window based on the location of main window.

So far I've been using AvalonDock for similar functionalty. You might give it a try...
