Answer 1

I do not agree completely with the assertion that DevX developers missed the mark on WPF. However, I will say that it appears they may have had a steep learning curve to overcome. Lets face it, WPF is massive. To master it, even out of the box, is a daunting task. I do agree that DevEx controls will not fit into a MVVM pattern, but they do sit quite nicely in a MVP pattern. "Can you suggest an alternate vendor of WPF controls?" No, but I will suggest that you study additional patterns if you are stuck with DevEx.
