Treeview'Expanded Property

[James Zukowski]

This one is VERY wierd: I can expand/collapse a treeview list by setting ID'Expanded=value. However, when I try to read the value (Var=ID'Expanded), I get Error#88.

Any ideas?

Did you set the 'item property first to identify which item in the list you want the expanded property for?

That was it. Not having worked much with Treeviews, I presumed that the user double-clicking on an entry would have specified what I'm looking for.
