Sending Custom SchedulerInfo to the CreateRecurrenceException web service method

[Andrew]

I have a derived version of the SchedulerInfo class that is properly being populated in my GetAppointments Web Service Call...

[WebMethod(EnableSession = true)]
public IEnumerable<AppointmentData> GetAppointments(CustomSchedulerInfo schedulerInfo)
{
        return Controller.GetAppointments(schedulerInfo);
}

However I noticed when the CreateRecurrenceException web service call is made it DOES send my custom scheduler info to the web service call but once it hits the Update method in my overridden SchedulerProvider it appears cast as type SchedulerInfo.


Note that also when I update a schedule item which is not recurring the Update method is called with the CustomSChedulerInfo.

An exert of my overriden SchedulerProvider

public class SchedulerProvider : DbSchedulerProviderBase

    {

        public override IEnumerable<Appointment> GetAppointments(ISchedulerInfo schedulerInfo)

        {

               var scheduleInfo = schedulerInfo as CustomSchedulerInfo;

        }

 

        public override void Update(ISchedulerInfo schedulerInfo, Appointment appointmentToUpdate)

        {

               var scheduleInfo = schedulerInfo as CustomSchedulerInfo;

//NOTE: When this is called from the CreateRecurrenceException web service call that
scheduleInfo is cast as null.  When this is called from the UpdateAppointment web service call
scheduleInfo is properly cast.



        }

}

Hi Andrew,

We have had this problem reported recently. We confirm that this is a glitch with RadScheduler, which we will fix for Q2 2011 at latest.

Please, excuse us for this.

Best wishes,

I've checked the release notes but do not see where this item has been addressed as of yet.  I'm running into the same issue as discussed here and am looking for a resolution.  Thanks.

Hi David,

Unfortunately, we have postponed fixing this bug in favor of some more urgent issues. Please, accept our apologies for this.

All the best,

I came across this bug too - it's quite annoying.
However I found a work around. Part of the internals workings of "CreateRecurrenceException" are to first call "GetAppointments" on the controller before calling the insert/update/delete methods. And although the insert/update/delete methods are called with the default SchedulerInfo class as a parameter, the GetAppointments is called with the SubClassed custom one.

So the work around is to have an instance variable on your controller class, e.g:

private FilterSchedulerInfo _filterSchedulerInfo;

And in the "GetAppointments" method, set this variable to the passed in one. e.g:
   

public override IEnumerable<Appointment> GetAppointments(ISchedulerInfo schedulerInfo)

{

    //Telerik Bug - http://www.telerik.com/community/forums/aspnet-ajax/scheduler/sending-custom-schedulerinfo-to-the-createrecurrenceexception-web-service-method.aspx

    //Supposed to have been fixed in 2011 Q2 release but still not fixed.

    //Calls to Update from the web service only pass a default ISchedulerInfo when called from CreateRecurrenceException. But immediately befre, I found that GetAppointments

    //is called with the correct sub class. So we grab a copy here and store it. Then our methods can use this if they receive the default only class.

    _filterSchedulerInfo = (FilterSchedulerInfo)schedulerInfo;

//etc
}

Then, in the insert/update/delete methods, test for the type and replace the variable accordingly.

public override void Update(ISchedulerInfo schedulerInfo, Appointment appointmentToUpdate)

{

    //See bug description in GetAppointments method above.

    if (schedulerInfo.GetType().Name != "FilterSchedulerInfo")

    {

        schedulerInfo = _filterSchedulerInfo;

    }

//etc
} 



If the bug is ever fixed, then the if statements will be skipped so hopefully no need to remove the workaround.
Hope this helps.

Hello !

I think I report the same bug, but i'm using a RadScheduler with WebService binding, and a custom ISchedulerInfo. All is fine fot Get, Insert or Update but not Delete ; in the overrided method of the provider, the cast (MySchedulerInfo) schedulerInfo doesn't work ..

Have you ever seen this problem ?
Do you know what happen ?

Thank you for your help.

Marc-Antoine.

Hello Peter,

I've updated my version of Telerik by 2012.1.411.35, cleared my caches and updates my VS references but it still don't work ..

public override void Delete(ISchedulerInfo schedulerInfo, Telerik.Web.UI.Appointment appointmentToDelete)

in the provider delete method, the type of schedulerInfo after cast is Telerik.Web.UI.SchedulerInfo.

According to my web method, the schedulerInfo should be ApplicationSchedulerInfo typed ..

[WebMethod]
public IEnumerable<AppointmentData> DeleteAppointment(ApplicationSchedulerInfo schedulerInfo, AppointmentData appointmentData, bool deleteSeries)
{
    return Controller.DeleteAppointment(schedulerInfo, appointmentData, deleteSeries);
}

Thank you for your Help,

Marc-Antoine.

The issue does not appear to be fixed in build 2012.1.529, I am getting a invalid cast exception in the overiding GetAppointments for my Schedule Provider.

Hello Joe,

Thank you for letting us know of this, but we cannot replicate the problem at our side.

Can you verify that you have successfully upgraded and that you are using the latest build by inspecting the rendered output of your page (please see the attached image).
