A good source are the Ultra Controls and although mostly using Infragistics Ultra components should point you in the right direction:

As Cringer outlines there are other .NET style libraries available and one is included with Windows.

You have to create a .NET form and add the TreeView control to the form. If you have Progress Developer Studio this can be done using Visual Designer and add the TreeView from Microsoft Controls.

I have not actually used the .NET TreeView control in Progress but downloaded an example a while back and this is attached. Very basic and is also embedding an ABL Window into a form which you may not be looking for but hopefully it should get you started.

I have some example code of dynamically adding nodes and sub nodes to a .NET TreeView and this is attached.

It does not do exactly what you require as it dynamically adds when first run and not when a node is clicked, but hopefully it gives you some ideas and you can adapt.
