I use 2015.1.401.
Why does the AppointmentCreated event fire AFTER the Page_PreRender? I want to get a count of certain Appointments and it seems like the perfect place for that is in AppointmentCreated (where I already have alot of other appointment related logic). And then in Page_PreRender I want to use those counts to write out a label to the user to give them some statistics about their appointments.
Is there a different event I can use?
