extree - sample code

Does your control support partial-check ( three states ) feature for each column?

VBA (MS Access, Excell...)

With Tree1
	.LinesAtRoot = -1
	With .Columns.Add("P1")
		.Def(0) = True
		.PartialCheck = True
	End With
	With .Columns.Add("P2")
		.Def(0) = True
		.PartialCheck = True
	End With
	With .Items
		h = .AddItem("Root")
		.InsertItem h,0,"Child 1"
		.InsertItem h,0,"Child 2"
		.ExpandItem(h) = True
	End With
End With
