I have a WPF app which hosts a WindowsFormHost. The WindowsFormHost loads ESRI's ArcEngine. The ArcEngine has some drawing functions available but I'm looking for more power and control. Assuming I want to draw some images & text on the screen over the image created by the ArcEngine, what are my options, if any?
A WPF window cant render anything over any winforms elements that it contains. You either need to do the drawing within the winforms element or do a nasty hack of creating a separate WPF window with a transparent background & no border that you programatically move around to keep on top of the winforms element - then you can draw into this overlay window using WPF mechanisms. it's ugly but effective.
