Hi Cetin,

Thanks for your reply. So if you programatically check or uncheck the checked property the nodechecked event doesn't fire? Then how can we determine if someone checks or unchecks an item?

This is how I set it up. 'MakeLink' is a function I've made to determine if the checkboxed should be checked. 'IsExpanded' is a function that determines if the node was previously expanded.

scan  && scan table full of treeview values
	if empty(tparent)
		loNode = thisform.acxTreeView.nodes.add(, , alltrim(tname), alltrim(tdescrip))
	else
		loNode = thisform.acxTreeView.nodes.add(alltrim(tparent), tnum, alltrim(tname), alltrim(tdescrip))
	endif
	if thisform.makelink(alltrim(thisform.txtPid.value), alltrim(tname))
		loNode.checked = .t.
	endif
	if thisform.isexpanded(alltrim(tname))
		loNode.expanded = .t.
	endif

endscan

Thank You Very Much,
Chris
