VB Net, SQL, and TreeView 2021 07 17

VB.Net and TreeView I'm doing my usual, and experimenting with VB.Net. A Treeview is what it says - it gives you a view of a parent, with children and grandchildren - how many levels just depends on the requirements. I have engineered this 'little' application (it started out small, and then sort of grew...don't they all?) There is an admin screen, where you set the 'root' name, and there is a datagridview that shows the current data table, which is used to populate the tree. I have looked at some examples on the web, and there looks to be many different ways to approach this. Mine may not be the best, but it works for me! There is a 'root' and this is you, or your Company's name. This is put together to have a list of Company, Department, and Team. It allows for the same Department to appear in multiple Company references, and the same named Team may appear multiple times, too. By right-clicking a node you get a menu that allows you to add, delete, or rename a node.
