Generate Treeview Sample Code (VB.NET)

This sample demonstrates usage of recursive concept to generate a hierarchical (parent-child relationship) collection of objects into a treeview in order to visualize the hierarchy.


It also demonstrates two similar methods of generating the treeview.
  1. Using default thread (GUI thread)
  2. Using new thread (multi-thread).
The multi-threaded method can be useful when generating a treeview of a big hierarchy. It will allow the treeview to load on as-ready basis. Means that the treeview will get to refresh (the screen) every time a node is added.

As compared to using default thread, the treeview will only get to refresh (the screen) after all nodes have been added.

Refer to following diagram for the sample object hierarchy for this scenario.
