I thought the same about the shortcomings of needing code in any form that uses the control.
I tried the 'StaysOpen' idea on a simple popup and (apart from the need for the extra click which you witnessed) it worked consistently so maybe your control could be tweaked somehow.

Another possiblility (not tested):
Create a subclass of ElementHost to hold the WPF control. In its constructor you could then use FindForm() to get a reference to the WinForm and hook up the Forms Move event (etc) to code in the WPF control to close the popup.

The problem with that is that even if it solves for Winforms the problem still exists in a WPF environment. I'm not sure what the advantage of using the CreateRootPopup as per the example is - have you tried the simpler approach of just using your control as content of a popup? Of course, there may be no advantage there either - but at least it's simpler to comprehend :-}
