Same answer as last time - the control has nextnode and previousnode methods.

Excuse me, why do you keep asking?

You did not even specify which type are your looking at. TreeView is not a type, this is just a common name for several classes; I immediately can remember 3 of them. In a way, you are asking about something which does not exist in actual reality.

Please, provide fully-qualified names and tag you application type and UI library.

Check if the property tells you that there is no next node.
