If you look on the web page
You'll see one of the screenshots shows exactly what I
think you are trying to do - two tree controls with lines connecting nodes from one tree to the other.
The really neat thing is that the lines automatically update to maintain connection even as one or the other tree is scrolled.
This was done using the TList 8 OCX control ( for the tree ) and the MetaDraw 3 OCX control ( for the lines ) . The screenshot was taken based upon implementing this in a windows EXE application but the same could be done with TList and MetaDraw in a Web page. However there would be a limitation to IE as the web browser. If you need this for an internal company project maybe this would work for you. If needed for general public the IE limitation may not be workable. If it's ok for you, let me know and I can send additional information on TList and MetaDraw.
