TBaseVirtualTree.Assign Method

Used to copy properties from another Virtual Treeview.

procedure Assign(Source: TPersistent); override;

Although this method assignes most tree properties it does not assign the header and the nodes to the new tree. There is an own method (TVTHeader.Assign) for the header assignment. In order to copy the nodes you must save them to a stream and restore them in the other control
