For some time now there has been a debate among my companies designer, about the space required by a tree control. So we talked about some various solutions, and the correct one for me, is that we must implement a custom control based on our needs.

For example

The idea is not entirely mine. It is basically a copy of the path selection control in Windows Vista Explorer’s address bar.
