As we rewrite most of the code of the CoverFlow control we decided that this event is not needed any more as you can put any visual elements as items an hook up the their events. Please refer to the following example that shows how to implement this with the new version of the CoverFlow control: http://demos.telerik.com/silverlight/#CoverFlow/DataInfo
All the best,
the Telerik team
