Hi Neill Murphy,
I just checked and indeed there is some code missing in the documentation. We will correct that.
Neill was kind enough to post the missing code (thank you Neill). This code is from the Binding
example from the Q3 2008 release.
These callbacks are called (if specified) each time before a value is set to a scheduler object (usually of type Appointment) or to a data source object (usually some kind of business object that stores appointment data). They allow you to change the value if needed.
In Q1 2009 release this code became part of the AppointmentMappingInfo so that you do
not need to type it every time you bind RadScheduler. Of course if the default implementation is not suitable for your case you can always change it. (This is a topic for another help article / blog post)
