>Anyone with more experience with treeview (that's just about everybody <g>) figured out how to get a different action with a single click (CLICK or NODECLICK events) and still preserve the normal expand collapse behavior of the double-click? AFAIK both click and nodeclick will fire every time doubleclick does, making separate actions just about impossible without some very funky code.

Ray,
I just set a flag in the Expand and Collapse to say that it was done then ignore that in the click ie.

* Expand/Collapse methods
Lparameters Node

ThisForm.lIgnoreClick = .T.
DoDefault(Node)

* Click method
*-- Ignore the click as it was used to Expand/Collapse a node.
If ThisForm.lIgnoreClick
	Return
EndIf

HTH
