first let me complement your control, it looks good and it's easy to use and code.
i want to try and do something with it, and i don't really know where to begin.
when Collapsed i want the expander to look different and be a little bit shown and put some buttons on it with icons,
something like the example i've attached (in both pictures the expander is Expended but you get the idea i think)
i thought about using its' events (PreviewCollapsed?) or something like that but i wonder if there is a better way.
can you help in some info on how to accomplish this?
thanks in advance.
