Very clever solution! I agree that leveraging the viewmodel is a much cleaner approach.
Do you think you could expand a little more on what's going on with your FlaggedEnumViewModel class?

I'd be happy to, do you have any specific questions? Really the brunt of what's going on is the translation of the convention-based property name into the associated flag, then checking against the underlying data to return the correct boolean, or set/clear the appropriate bit on the underlying value.

Excellent code. This is one of those "it-seems-like-it'd-be-easy" things that is explained really well. I'd like to see the author do some deeper discussion and maybe describe how to do dynamic binding in WPF.

Thanks! I do plan to do additional posts in the future, but time [and interesting topics] are hard to come by :)
