How to Improve the Performance with Schedule?

[Cooper]

1. Step 1:  I created the CustomAppointment.
   
    
     public class CustomAppointment : Appointment, IDisposable
       {
           public CustomAppointment();      
           public string  Birthday      
           public string Dr_id       
           public string Dr_name           
           public int EventID      
           public string User_id     
           public string User_name      
           public void Dispose();
           protected virtual void Dispose(bool disposing);
       }
   
   
   Step 2:  I created the list<CustomAppointment>to read data from Visual FoxProDB.
   
    
   Setp3:  I added list<CustomAppointment>to schedule.Appointment.addRange.
    
   
   Question:  How to improve the performance when list<CustomAppointment>
   added to schedule.addRange?
   
      
   private void bindRadSchedule1(stringstrStartDay, string strEndDay, int intDutyIndex, string[] strFirstDuty, string[]strSecondDuty, string[] strLastDuty)
           {
               try
               {
                   List<CustomAppointment> liCustomAppointments = new List<CustomAppointment>();
    
            switch (intDutyIndex)
                   {
                       case 1:                       
                           liCustomAppointments =reloadAppointUsers(hidden_dr_id.Text.ToString().Trim(), strStartDay,strEndDay, strFirstDuty[0].ToString().PadLeft(2, '0'), strFirstDuty[1].ToString().PadLeft(2, '0'));
                           break;                
                       default:                       
                           liCustomAppointments = reloadAppointUsers(hidden_dr_id.Text.ToString().Trim(),strStartDay, strEndDay, "", "");
                           break;
                   }
    
                   this.radScheduler1.Appointments.Clear();               
   
                   radScheduler1.Appointments.AddRange(liCustomAppointments.ToArray());  
     
                   dtHoilday =boundAppointmentObj.listDoctorOffTime(hidden_dr_id.Text.Trim(), strStartDay,strEndDay);               
                   radScheduler1.SchedulerElement.Refresh();
               }
               catch (Exception ex)
               {
                    writeObj.writeToFile(DateTime.Today.ToString("yyyyMMdd") + "_scheduleError", Directory.GetCurrentDirectory(),
                   "bindRadSchedule1  函式錯誤  輸入參數區間" + strStartDay + "~" + strEndDay + "班別" + intDutyIndex + " 錯誤訊息" + ex.Message);
               }
           }

Hello Cooper,

Thank you for writing.

The possible solution, which I can suggest to improve performance in data loading, is to use the RadScheduler.Appointments BeginUpdate() and EndUpdate() methods. Place BeginUpdate() and EndUpdate() just before and after blocks of code that add large numbers of appointemnts. I have attached a sample project as well.

I hope this information helps. Should you have further questions, I would be glad to help.
