Preventing Appointment Conflict

[salman]

Hello,

Do you know the best way of preventing the appointment conflict while creating a Recurring appointment?

For example, let see if I already have a resource reserved for 08/1/2008 between 9AM to 12PM on Friday .
When I try to create a new appointment with the same resource today as a recurrning appointment, Weekly, Every Friday, 10 occurences.  Now, it should not let me create the appointment since there is a conflict.

I will really appereciate if you can either direct me what to do here or show a some sort of example.

Thank you,
-Salman

Hi Salman,

Thank you for your question. We might add this functionality in our online examples. Meanwhile, I am sending you a sample for reference (please, find it attached). The key point here is to loop through all occurences and campare their times.

protected bool ExceedsLimit(Appointment apt, DateTime recurrenceDateTime)
        {
            int appointmentsCount = RadScheduler1.Appointments.GetAppointmentsInRange(recurrenceDateTime, recurrenceDateTime.Add(apt.Duration)).Count;
            return (appointmentsCount > AppointmentsLimit - 1);

            //occurrence.ToString(), occurrence.Add(a.Duration);


        }

        protected void RadScheduler1_AppointmentInsert(object sender, Telerik.Web.UI.SchedulerCancelEventArgs e)
        {
            if (e.Appointment.RecurrenceRule != "")
            {
                RecurrenceRule parsedRule;
                RecurrenceRule.TryParse(e.Appointment.RecurrenceRule.ToString(), out parsedRule);

                foreach (DateTime occurrence in parsedRule.Occurrences)
                {
                    if (ExceedsLimit(e.Appointment, occurrence))
                    {
                        Label1.Text = "Another appointment exists in this time slot.";
                        e.Cancel = true;
                    }
                }
            }
            else
            {
                if (ExceedsLimit(e.Appointment))
                {
                    Label1.Text = "Another appointment exists in this time slot.";
                    e.Cancel = true;
                }
            }
        }
