Well, it worked for me as long as I had Form>Container>TV

Once I started with form>Container1>Container2>Container3>tv, it no longer worked

Setting the tv.Visible to FALSE before resizing is essential

When I refreshed Container2 after resizing, it worked again. Thisform.Refresh also works

tv_visible = tv.visible
tv.visible = FALSE

now resize

tv.visible = m.tv_visible

=tv.Parent.Parent.Refresh() && parent of container of tv

In fact, this is the code of Container3 which contains the treeview

&& Container3.Resize_Post()

local Visible

with m.this

	Visible= .Visible 
	
	.Visible = FALSE && assign method, below

	=.Treeview.Move(0, 0, .Width, .Height )
	
	.Visible = m.Visible
	=.Parent.Refresh()
endwith


&& Container3.Visible_assign
LPARAMETERS vnewval

=DoDefault(m.vnewval)

with m.this.Treeview
	
	.Visible = m.vnewval

endwith
