How to restrict the start and end times of an appointment?

Hello Denny,

To achieve this requirement, you could create a new class that extends the ScheduleViewDragDropBehavior object and overrides the CanResize method. In it, you could check the start and end values of the appointment and return false if they are lower than 10 minutes (or a different span depending on your requirements).

I hope the provided information will be of help to you.
