You can get all appointments for a certain period by using GetOccurrences
method. If you loop through the AppointmentsSource of the ScheduleView and call this method for each appointment, you'll get the needed result. After that you will be able to count them and display them where is suitable for you.
You can edit very easy the template of the ScheduleView with Expression Blend. Just drop a ScheduleView control on the design surface, right-click it and choose from the menu Edit Template -> Edit a Copy
Hope this information helps. Please let us know if you have further questions.
All the best,
