I have placed this control on a form.

When I press the right mouse button I bring up a shortcut(popup) menu with several options. Namely, Expand, Collpase, Add, Edit Delete.

I am having difficulty in trying to programatically Expand or Collapse a branch.

Has anyone done this?

I pass the object reference of the Outline control to my shortcut menu as oRef. In the procedure for the Expand menu item, I have oRef.Expand(). This did not work.

I tried giving it the ListIndex as a parameter - oRef.Expand(oRef.ListIndex). Again, it did not work.

I had similar results with oRef.Collapse()

It is a safe guess that it can be done, I just don't know how. Any clues?
