If I'm using a ListView in virtual mode then, as I understand it, the list view only keeps track of a small number of items in the list. As the user scrolls it dynamically retrieves items it needs to show from the virtual list.

But what if an item is added or removed from the master list? If an item is added/removed outside of the range of indexes being shown by the list view then I would assume the list view would show the added/missing items when the user scrolls to that index. Is this correct? But what if an item is added/removed from the range of indexes the user is currently viewing? How do I trigger the list view to refresh the items it is currently viewing to show the new/missing items?
