treeview for browsing directories

[Piz]

Hi all.
I would like to place in my asp .net 2.0 website a treeview control
that allows the user to browse directories and all of its
subdirectories from a certain root.
I don't know so much about node, and how to use them to populate my
treeview. Someone could help me....
I think this is a common problem, so maybe there's a place where i can
i find code already written that solves my problem. But i can't find
it.

Thanks to all

Bye
