How to prevent overlap appoitments?

[sano-apps]

Hi,

I have implemented a function within the Scheduler class to prevent the creation of overlapping appointments. The CheckAppointmentOverlap method checks if a given date falls within the range of existing appointments. By calling this function, I can ensure that appointments do not overlap when initiating a drag operation. However, I am currently facing challenges in preventing the ability to end an appointment on an existing appointment.

public bool CheckAppointmentOverlap(DateTime date) { foreach (var existingAppointment in _appointments) { // Check if the given date falls within the existing appointment range if (date >= existingAppointment.Start.Date && date <= existingAppointment.End.Date) { return true; // Overlap detected } } return false; // No overlap }

and call it from here:

` public void BeginDrag(SchedulerDay day) { if (!EnableAppointmentsCreationFromScheduler) return;

 if (_appointments.IsNotEmpty())
 {
     if (CheckAppointmentOverlap(day.Day))
     {
         return;
     }
 }

 _draggingStart = _draggingEnd = day.Day;
 _showNewAppointment = true;

 _draggingAppointmentAnchor = _draggingStart;
 StateHasChanged();

} `

Any idea how to prevent that?
