Tree

The tree control is used to show hierarchical organized data as a bill of material,
projects, directory structure on a hard disc, and more.
An example from the standard application is the project table. Click Edit on theAll Projects list page. 



The forms tutorial_Form_TreeControl illustrates many of the functions related to
the table control and shows how they are programmed in X++.
When working with tree structures with significant amount of nodes, only build
the visible part of the tree and extend the depth of the tree as the nodes are
expanded.
