>One nice thing about the TV is the node's "key" member. That's useful if I want to cross-reference the node to different entities. Say, I've got (1)Manager-(2)Supervisor-(3)Employee. I use "Manager_"+BINTOC(Manager.Manager_ID) for the key and "Supervis"+BINTOC(Supervisor.Supervisor_ID). Click on the node, and interpreting Node.Key tells me which record from which table to look at.

I actually place the cursor/DBF key values in the key member to point to source data when a node is clicked. It's also a great way to check a node's availability: TYPE('oTV.Nodes(lcKey).key')=="C"

I also have a project with 4 list views and a treeview. All the OCX's fire the same NodeClick event. It's amazing what can be done with those guys!
