Ok, I found this help link, which allowed me to visually wire everything up.
http://www.telerik.com/help/silverlight/radscheduleview-features-customizing-dialog-windows.html
From inside of my Dialog, how do I:
a)Data Bind my controls to the selected appointment of the ScheduleView
b)Save an edited appointment
c)Save a newly created appointment?
Thanks a bunch!
