Get all appointments at a specific date/time

I found another post about this.

I will look at it first

Hello, Patrick,  

Indeed, the referred forum post offers a suitable approach for extracting the appointments in a certain interval. The GetAppointmentsInInterval method that the SchedulerMultiDayView offers will give you what you want. 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
