Well, you need some way to associate the items to display in the second
listview with entries in the first one. How you do that is completely
dependent on how you store your data. If you have one list object for each
account it would make sense to store the reference to the list object into the
TListitem.Data property of the items in the first listview. You then use a
suitable event to detect when the user selects one item (i.e. oNSelectItem),
retrieve the object reference from the items Data property and hand it to a
routine that fills the second listview.
