addOnBeforeSelect	Assigns a delegate to the beforeSelect event.
addOnItemDrag	Assigns a delegate to the itemDrag event.
beginUpdate	Maintains performance while items are added to the tree view control one at a time by preventing the TreeView control from painting until the endUpdate method is called.
