Dear Support,
I need to know when the user collapse/expand a node in the tree.
I override OnTreeGridToggleItemExpandedState, but i have two problems with it:
1) It gives me a row number, and not an HTREEITEM - how do I get HTREEITEM from row number?
2) It always gives me in nAction TVE TVE_TOGGLE, no matter if I collapse or expand. Why is this?
Thanks,
Ron.

HTREEITEM hTreeItem = ItemGetByVisibleRowIndex( nRowNo );
OnTreeGridToggleItemExpandedState is called from one single place in Prof-UIS source code, with the default TVE_TOGGLE as 3rd parameter. But you could check the state with ItemIsExpanded(hTreeItem); before or after calling base-class method.
