Description
Represents the event handler for events that notify a tree view of changes to one of its nodes.
TTVExpandedEvent is used to respond to notifications of events that occur to the nodes of a tree view control. It is a generic event handler for various events that notify the tree view of something that happened to a node.
Sender is the tree-view control that contains the node that is the focus of the notification.
Node is the item that has been expanded, collapsed, deleted, or which is about to be drawn.
