Hi,

Is there any example code setup to show how to use an AppointmentComparer?

I've tried setting one up, but it never seems to get called.

I'm using a RadScheduler with WebService binding, would that have any impact in why it doesn't seem to be working?

In the Page_Init method I have the following code:

    
            RadScheduler1.AppointmentComparer = new AppointmentComparer();

And I have an AppointmentComparer.cs file with the following code:

    
            public class AppointmentComparer : IComparer<Appointment> 
        
            { 
        
                #region Constructors 
        
                public AppointmentComparer() 
        
                { 
        
                } 
        
                #endregion 
        
                int System.Collections.Generic.IComparer<Telerik.Web.UI.Appointment>.Compare(Appointment first, Appointment second)  
        
                {

But the breakpoint in the Compare method never seems to be reached.

Thanks very much for all your help,
Greg

Hello Greg,

The appointment sorting is a bit different when using web services. The sorting actually happens on the client, so we need to override the default compare method. This is an instance method and takes the appointment to compare to as an argument.

For example, you can sort appointments alphabetically:

// Place the script block immediately after the ScriptManager on the page

Telerik.Web.UI.SchedulerAppointment.prototype.compare = function(otherAppointment)

{

var subject = this.get_subject();

var otherSubject = otherAppointment.get_subject();

if (otherAppointment == null)

returnValue = 1;

else if (subject == otherSubject)

returnValue = 0;

else if (subject < otherSubject)

returnValue = -1;

else

returnValue = 1;

return returnValue;

}

Our documentation is indeed lacking such example. We'll take care to fix this.

I hope this helps.

All the best,

Hi,

To sort appointments by some custom criteria, you should use the AppointmentComparer property of RadScheduler as shown in this forum post:
http://www.telerik.com/community/forums/aspnet-ajax/scheduler/oder-of-entry-in-scheduler.aspx#1155620

For Web Service binding mode, please see this forum post:
http://www.telerik.com/community/forums/aspnet-ajax/scheduler/example-of-how-to-use-an-appointmentcomparer.aspx#1188449

Feel free to contact us if you have further questions.

What is needed to sort the appointments by the datasubjectfield? In my case, all of these are "All Day" appointments.

I added the code specified above to this, but nothing happens. Maybe it post left something out assuming the end user knows what should be done...

Basically, my datasubjectfield is an employee's name. I want this to sort alphabetically, but is not sorted in any way at all.

Resolved. Added the code below. The Telerik Code Converter failed me. First, the code samples provided above was missing a closing bracket. Second, the converter failed to fully convert "Public Function Compare" code. The bold text was missing.
