DirtyChanged event?

Has anyone implemented the equivalent of a DirtyChanged event for BusinessBase-based classes? 

I have a user interface where one of the requirements is to indicate in the UI when the object being edited on the screen is dirty (put a * in the app's titlebar).  I'd love to do this with an event handler to minimize the code needed in the UI.

Or, perhaps one exists and I just haven't looked hard enough.  :)  I'm using version 2.1.

Just handle the standard PropertyChanged event. If you get one, then you know the object is dirty, because something just changed.

Rocky,

Oh, well -- duh.  Thanks.  I never thought of that!  I knew it could be something simple.

I really love what I've seen of CSLA so far.  Unfortunately I picked a really big project to do as my first -- I'm replacing the entire middle tier of a large application that was originally built using the Web Service Software Factory (not my decision). 

The learning curve been challenging so far -- even with the books.  But after all the internal struggle surrounding how to build my object library, the payoff is when I get to gut loads of unnecessary code in the winforms UI and use databinding instead.  :)

I really appreciate the help!  Maybe I'll bump into you @ DevConnections if you're there...
