Mr. Pieter
Picture above with red mark show where it was my fault because I was using Anode.DataInteger NOT ANode.Node.DataInteger and for that reason when I was trying to compare with the bitmapcontainer item.tag my algorithm was not working.
I needed a way to match an image container to a FNCTreeView item (node) so my user see a 24x24 picture of it.
Your tag property was working good always
Thanks
