Yeah!!! Attached behaviors for all of those things that need commanding that aren't commandable!!! Whohoo!!! How many more things do I need to know about/create to do my job? WPF is just one exception after the next... Binding CommandParameters works great too...oh wait.
A little bit of education now saves a ton of time in the future. Binding Command parameters couldn't be simpler, so I'm not sure why you're implying it's not.
