Does anyone know of a really user friendly outline or tree view control that can be obtained for free or at a reasonable price ?

As an amateur, I find the work involved in setting up such an interface cumbersome and wonder if there are any classes or VCX available that would allow for a truly intuitive building of such an interface.

I mean surely it's possible to set up a system where in a table or set of related tables, the parent/child contents are automatically read into the outline or tree ? Or perhaps I should try and do that as an exercise myself......!

Thank you,
Charlie
