Tnx for the suggest. That's what Im trying to achieve.
But Im facing a problem right now:
Another of my requirements is to implement a sort of modal window on top of the shell. (you know, the ones that dim the background).
Im trying to implement a new ModalPopupDialogActivation and a new ModalPopupWrapper.
Inside this one, Im trying to use the WPFToolkit Extended's Child Window, but for no reason Im able to make it work.
IS there another fancy-pants way to achieve this?
