The DriveInfo class has the ability to find all Drives on the system. You’ll need an Imports statement for the System.IO namespace. ' The placeholder string below is never shown, ' because the node begins in collapsed state.ĪddHandler item.Expanded, AddressOf item_Expanded
Private Sub MainWindow_Loaded(sender As Object, e As RoutedEventArgs) Handles Me.Loadedįor Each drive As DriveInfo In DriveInfo.GetDrives() The Loaded event code I used is almost unchanged from his original: If the link is still working, you can see the relevant pages here. As I mentioned above, I’ve hijacked some code that Matthew McDonald published in his Pro WPF 4.5 in VB book. The Treeview is populated with the list of Drives on the system as soon as the Window is loaded. I think though that the code below – with a couple of minor tweaks to the classes used – will work just as well if you want to use Windows Forms. I’ve used WPF for this because I eventually want to add images to the TreeView (and maybe the ListBox) and this will be easier to do in WPF than Windows Forms. I’ve drawn on sample code first published by Matthew McDonald and Charles Petzold and then tweaked it for my purposes. So the example below displays the Drives and Folders in a TreeView and then shows a separate file list in a ListBox. I would have liked to do this all in a TreeView and, although I (kinda) succeeded, I didn’t like the finished product.

That question got me wondering about how to take things a stage further and have all the files in a selected folder listed and then open that file (if possible) when a file names was selected. Someone posted a question about the display of Drives and Folders in a TreeView recently.
