Remarks

The ActivationActionDelay and ActivationInitialActionDelay properties and ItemActivated event can be used to simulate the Live Preview functionality found in Office 2007 applications (e.g., Word). Specify a delay that makes sense for the preview you are doing (e.g., longer delay for more expensive previews so that your application is not constructing previews everytime a GalleryItem is moused over), and handle the ItemActivated event to display the preview.
