Public Sub Expand( ByVal Style As ExpandStyleEnum )
If items are already expanded when using Expand, the items remains unchanged. It does not make any indirect dependents visible. To make sure that an item's indirect dependents are shown, use the ItemClass.Collapse or ItemCollectionClass.Collapse methods first, which collapse the items (and all dependents), followed by Expand. Now all dependents are visible.
