Another commercial product you may want to consider is Infralution's
Virtual Tree. In addition to supporting multiple customizable columns
you can also change the displayed columns (using Context Sensitive
columns) when the available space changes (just like Outlook). The
evaluation includes an "Advanced Features" sample that demonstrates
how to do this. You can get more information and download an
evaluation version from:
www.infralution.com/virtualtree.html
