Please find the attached project and give it a try. Basically, It uses GetitemByPathMethod supposing that source and destination tree have identical structure. If you need to synchronize this structure when you drag a treeNode (or subtree) from the left tree(the source) and the right tree (destination ) , you can use the ItemPrepared event of the RighTtree , make a deep copy of the Item (subtree) you are dragging and place it at the corresponding place in the left tree. Feel free to ask if you need further assistance.
