Loving this… the part where you generate the eventhandlers seems like magic …
I want to use it in a project, but just to be sure what is the license of it?

Go it… so silly, it was a binding problem.

Cheers.

Hi, nice work!

But I’m having a problem, I’m trying to fire MouseLeftButtonUp as a Command but I always get null exception at CommandBehaviorBinding line 99. It seems that strategy is null. Any thoughts?

It also happens with Actions.

Hi Marlon,

could you please elaborate a little on the Behavior hack?
You simply write “it’s a trick to get it work” in the comment for the BehaviorsPropertyKey a.k.a as BehaviorsInternal.
But could you tell me why it does work then?
Some for the “hack” with the freezable collection and so on. I can see that it really only works with the freezable… but why?

Besides, does really nobody have a clue why the Cider designer does not work with the behavior collection? Its really anoying.

But anyhow, great work Marlon, I love this behavior.

I tested it the other day in VS 2010 Beta 2 and it worked so unless they do something completely stupid done between now and when they release ….

I am getting this error in xaml
The attachable property ‘Behaviors’ was not found in type ‘CommandBehaviorCollection’.

Code runs fine. But I can’t viw design screen.
Can you please let me know how this can be corrected?

Just to let you know marlon I think ACB is a great idea and fills a very real need when doing MVVM. As its been said before, “Some times you just need to get the event args”.

Plus there are a couple of cases where i want to take action off of an event that aren’t linked to any specific Command.

So thanks a bunch.
