getting to treeview node

[Guest]

hey all,
i have a treeview on my web page. there are checkboxes on all the nodes.
when a node is checked i'd like to be able to change the backcolor of the
node.

how would you do this?

also,

what if you didn't want the link to act like a link to somewhere and just
wanted it to be a label?

thanks,
rodchar
