How to insert a node into a treeview?
How do you INSERT -- not add -- a new item into a Treeview using VB.NET 2005?
For instance, if the user clicks on Parent 0, Child 2... the new item will be inserted into Child 2's position and Child 2 will move down.
Treeview Format:
Parent 0
Child 0
Child 1
Child 2
Parent 1
Child 0
Child 1
I've tried this but nothing happens -- no error messages, either. It's driving me nuts! Please help!

If I wanted to insert an existing treenode to another position, I'd have to Clone it first then remove it before inserting, right?
