Can An Object Know About Itself?

Scott,

I re-watched a seminar from the 09 RevLive by Trevor DeVore recently about behaviours and one thing he pointed out was that a behaviour acts like a back script for a control, but if I understood him correctly, he also mentioned that when behaviours are applied to controls, there are more commands available, namely preOpenControl, openControl, closeControl and resizeControl.

Not sure if it would help, but it sounds like the closeControl may be useful to you, I would need to scan the video again to be sure and I am about to go out, but I'll certainly have a look when I get back.

Paul
