Linking appointment occurences with recurrence series in Schedule

When I want to edit an occurence of a recurring appointment, the occurence loses its link to the series. The occurence in the Schedule does not show the recurring-icon and I am unable to select "Edit Series".

My - simplified - schedule is set up like this:

@{Html.EJ().Schedule("Schedule")
                  
                  .Views(new List<string>() { "Day", "Week", "Workweek", "Month" })                          
                          .Orientation(Orientation.Horizontal)                          
                          .EnableLoadOnDemand(true)
                          .Group(gr =>{gr.Resources(Model.ScheduleGroupings);})
                          .Resources(res =>
                          {                             
                              res
                                 .Field("EmployeeId")
                                 .Title("Employee")
                                 .Name("Employees")
                                 .AllowMultiple(false)
                                 .ResourceSettings(fields => fields.Datasource(Model.EmployeeResources)
                                    .Text("Text")
                                    .Id("Id")
                                    .GroupId("GroupId")
                                    .Color("Color")).Add();

                               if (Model.ScheduleGroupings.Contains("EmployeeGroups"))
                              {
                                  res
                                     .Field("EmployeeGroupId")
                                     .Title("EmployeeGroup")
                                     .Name("EmployeeGroups")
                                     .AllowMultiple(false)
                                     .ResourceSettings(fields => fields.Datasource(Model.EmployeeGroupResources)
                                        .Text("Text")
                                        .Id("Id")
                                        .GroupId("GroupId")
                                        .Color("Color")).Add();
                              }

                          })
                          .AppointmentSettings(fields =>
                          {                              
                              fields.Datasource(dataSource => dataSource.URL("/Schedule/GetCaseTasks")
                              .EnableAjaxCache(false)
                              .Adaptor(AdaptorType.UrlAdaptor)
                              )
                                    .Id("Id")
                                    .Subject("Subject")
                                    .StartTime("StartTime")
                                    .EndTime("EndTime")
                                    .Description("Description")
                                    .AllDay("AllDay")
                                    .Recurrence("Recurrence")
                                    .RecurrenceRule("RecurrenceRule")
                                    .RecurrenceId("RecurrenceId")
                                    .RecurrenceExDate("RecurrenceExDate")        
                                    .ResourceFields(Model.ScheduleResourceFields);
                          })                          
                          .Render();
    }

My controller returns the following appointments:

[    
    {
        "Id": 323,
        "Subject": "Recur test",
        "Description": null,
        "StartTime": "/Date(1556766000000)/",
        "EndTime": "/Date(1556769600000)/",
        "Categorize": "",
        "EmployeeGroupId": "g2",
        "EmployeeId": "g2e7",
        "Priority": "",
        "AllDay": false,
        "Recurrence": true,
        "RecurrenceRule": "FREQ=WEEKLY;INTERVAL=1;BYDAY=SU,MO,TU,WE;",
        "RecurrenceId": null,
        "RecurrenceExDate": "5/7/2019"
    },
    {
        "Id": 325,
        "Subject": "Recur test",
        "Description": null,
        "StartTime": "/Date(1557198000000)/",
        "EndTime": "/Date(1557201600000)/",
        "Categorize": "",
        "EmployeeGroupId": "g2",
        "EmployeeId": "g2e7",
        "Priority": "",
        "AllDay": false,
        "Recurrence": false,
        "RecurrenceRule": null,
        "RecurrenceId": 323,
        "RecurrenceExDate": null
    }
]

Reading through the Schedule-documentation on various platforms my understanding is, that the occurence should only use the RecurrenceId value, and have recurrence disabled. I would like help with this, so that once an occurence is created I can still edit the series through the occurence. Hope it makes sense.

Hi Toke, 
 
Greetings from Syncfusion Support. 
 
We have checked the reported scenario by preparing sample but CRUD actions is working fine at our end. The same can be available in following link.  
 
 
Kindly check the above sample and if the issue persist still try to reproduce the issue in the above to proceed further.

It seems that setting the RecurrenceId (highlighted below) through the MVC Schedule has no effect.
Instead, the RECUREDITID property MUST be set in the RecurrenceRule for the occurence to stay attached to their recurrence series.
The RecurrenceExDate works as I would expect: it holds the dates of the 'activated' and deleted occurences, and, the dates does not have to be included in the RecurrenceRule. I would think the RecurrenceId would work in the same way? 

The only place RecurrenceId is mentioned in the MVC documentation (that I have been able to find) is under data-binding where it states the following: Binds the recurrence Id field which acts as a parent id for Scheduler recurrence appointments.

Is this working as intended?

...
.AppointmentSettings(fields =>
{                              
     fields.Datasource(dataSource => 
          dataSource.URL("/Schedule/GetCaseTasks")
          .EnableAjaxCache(false)
          .Adaptor(AdaptorType.UrlAdaptor)
     )
      .Id("Id")
      .Subject("Subject")
      .StartTime("StartTime")
      .EndTime("EndTime")
      .Description("Description")
      .AllDay("AllDay")
      .Recurrence("Recurrence")
      .RecurrenceRule("RecurrenceRule")
      .RecurrenceId("RecurrenceId")
      .RecurrenceExDate("RecurrenceExDate")         
}
...

Hi Toke, 
 
Thanks for the update. 
 
In your initial post, the edited occurrence data ( "Id": 325) has no recurrence rule, therefore it acted as normal appointment. When any one of the occurrence is edited, then the parent appointment id is added to edited appointment rule (like red) and the parent appointment rule is updated with the edited appointment date (like yellow). 
 
 
RecurrenceId is deprecated as we updated the edited occurrence appointment rule with RECUREDITID. Kindly make use of our previous CRUD sample. 
 
Regards, 
Karthi

Consider the issue resolved, thanks for the help.

But, what about RecurrenceExDate? Is that also deprecated? 
Supplying the "ExDates" directly with ReccurenceExDate works fine and they do not have to be in the RecurrenceRule. However, in the CRUD sample neither RecurrenceId or RecurrenceExDate is used, everything is supplied through the RecurrenceRule.

PS: The CRUD sample is not really set up for recurrence testing as the RecurrenceRule is nvarchar(50); barely enough to hold the simplest rule.

Hi Toke, 
 
Thanks for the update. 
 
No, RecurrenceExDate is functional. Most of the users requirement is to exclude some occurrence appointment in particular date during initial rendering, we provided RecurrenceExDate property for user convenience even though it can be achieved by altering the parent appointment rule with EXDATE. Since RecurrenceExDate is optional, we internally update the rule with EXDATE to handle the recurrence appointment in CRUD sample. RecurrenceId can be added only to the edited occurrence appointment and user requirement for RecurrenceId property is less as we maintain RECUREDITID in rule, we deprecated it. 
 
Sorry and kindly change the type to nvarchar(MAX). 
 
Regards, 
Karthi

Hi Karthigeyan,

I suppose that these rules (in yellow and red squares) apply also for ASP.NET WebForms. I have the following question in case it can be answered:

what happens if in parent appointment record, in field RecurrenceRule we don't include the EXDATE part at all (for any edited occurrence?

Thanks,
Petros

Hi Peter,


Q1: I suppose that these rules (in yellow and red squares) apply also for ASP.NET WebForms

Yes. The rule is applicable to ASP.NET WebForms too.


Q2: what happens if in parent appointment record, in field RecurrenceRule we don't include the EXDATE part at all (for any edited occurrence?

If you don’t include the EXDATE part of the RecurrenceRule, the parent recurrence appointment is rendered as usual, and the edited occurrence is also rendered as shown in the below snip. It’s mandatory to add the EXDATE to the parent appointment RecurrenceRule if any one of the occurrences of the parent appointment is edited.
