Most business applications need to display hierarchal data, and of course a TreeView has been the way to go for as long as I can remember. However, many situations arise where loading data in a tree can take quite some time. And this is what this article tries to address. All loading of items in this TreeView are done in a multi-threaded manner. So naturally when starting to learn WPF, the first thing on the list was how to get a TreeView up and running. I ran into a great article, which is the basis of my work, by Sacha Barber titled "A Simple WPF Explorer Tree".
