Loading time issue in the radscheduler

[Dev]

Hi,

When the record count is more than 500, the loading time of the appointments on the scheduler, loading time of the unassigned calls & drag & drop the assigned calls on the scheduler is taking more time to load, as we have used for loop function for binding the records.

To reduce the time taken we have used parellel.for threading concept but this is not applicable for the below functions.

=> scheduler.Appointments.Add(appointment)
=> scheduler.PerformLayout()
=> scheduler.Refresh()

It is a big problem for us, Can you please suggest if there a concept/method to reduce the loading time in the radscheduler? 

Video link mentioned below for your reference.

Hello, Rick,

Indeed, according to the provided sample video the appointments load slowly in RadScheduler. Since I am not familiar with the exact setup that you have on your end, it wouldn't be easy to conclude what slows down the events loading.

I suppose that you add the events via code to the RadScheduler.Appointments collection. Note that after adding each Appointment, a refresh operation in RadScheduler is being executed. Hence, the more appointments you insert, the more refresh operations you will get. Thus, the performance may be affected.

The possible solution that I can suggest is to wrap the add operation in RadScheduler.Appointments.BeginUpdate/ RadScheduler.Appointments.EndUpdate block. Thus, the layout will be suspended while you are adding appointments and only one refresh operation will be performed after calling RadScheduler.Appointments.EndUpdate method. It is expected to improve the load time considerably.

            this.radScheduler1.Appointments.BeginUpdate();
            for (int i = 0; i < 500; i++)
            {
                this.radScheduler1.Appointments.Add(new Appointment(DateTime.Now.AddDays(i), TimeSpan.FromMinutes(45), "A"+i));
            }
            this.radScheduler1.Appointments.EndUpdate();
