Everytime you click the TreeView, an object reference of the currently selected node is passed to the click. What you could do is subclass the treeview and add a property called ActiveNode. Then, other controls on the form could just refer to that activenode object. To start things off, in the Init() of the control, you could have code like this:

This.ActiveNode = This.Nodes(1)

Unlike other collections, the nodes collection is 1 based - not 0 based.

Then, in the click, you could have code like this:

This.ActiveNode = Node
