To mimic the LivePreview functionality available in Office 2007, handle the GalleryToolActiveItemChange event. This event fires as the user hot tracks over gallery items, or navigates around the items with the keyboard. The delay before the firing of this event can be controlled by the ActivationInitialActionDelay and the ActivationActionDelay. When this event is fired with a non-null gallery item, the live preview should be shown to the user, indicating the changes that would happen if they were to select that item. If the event fires with a null item, the user has left the item area of the gallery, and the live preview should be hidden. Note: The event will always be fired with a null item if the event has been fired with one or more non-null items.
