This property returns and sets a value that determines whether the child nodes of a Node object are sorted alphabetically. It also returns and sets a value that determines whether the root-level nodes of a TreeView control are sorted alphabetically.
object.Sorted [= Boolean]
Following are the settings for the Sorted property settings:
You can use the Sorted property in two ways: first, to sort the Node objects at the root (top) level of a TreeView control and second, to sort the immediate children of any individual Node object.
Setting the Sorted property to True sorts the current Nodes collection only. When you add new Node objects to a TreeView control, you must set the Sorted property to True again to sort the added Node objects.
