If everything goes according to plan and we start working on the virtualization next week, it should take approximately a week, at most a week and a half to finish it off. The easiest way to explain UI virtualization is to quote Bea Stollnitz
A control that supports UI virtualization is smart enough to create only the UI elements needed to display the data items that are actually visible on screen. For example, suppose we have a scrolling ListBox that is data bound to 1,000,000 items but only 100 are visible at any time. Without UI virtualization, the ListBox would create a million ListBoxItems – a slow process – and include them in the UI, even though only a hundred of them are visible. With UI virtualization, on the other hand, the ListBox would only create 100 ListBoxItems (or a few more, to improve scrolling performance).
Therefore, once we implement virtualization in the book, the control will display 4 pages at most which is necessary for a successful page flip.
