AddRecurrenceRequest Class

Contains the data that is needed to add recurrence information to an existing appointment.

Namespace: Microsoft.Crm.Sdk.Messages
Assembly: Microsoft.Crm.Sdk.Proxy (in Microsoft.Crm.Sdk.Proxy.dll)

public sealed class AddRecurrenceRequest : OrganizationRequest

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic.

// Specify the recurrence information that needs to be added to the
// existing appointment.
// 1.  Define an anonymous type to define the possible recurrence pattern values.
var RecurrencePatternTypes = new
    Daily = 0,
    Weekly = 1,
    Monthly = 2,
    Yearly = 3

// 2.  Define an anonymous type to define the possible values for days 
// of the week
var DayOfWeek = new
    Sunday = 0x01,
    Monday = 0x02,
    Tuesday = 0x04,
    Wednesday = 0x08,
    Thursday = 0x10,
    Friday = 0x20,
    Saturday = 0x40

// 3.  Define an anonymous type to define the possible values  
// for the recurrence rule pattern end type.
var RecurrenceRulePatternEndType = new
    NoEndDate = 1,
    Occurrences = 2,
    PatternEndDate = 3

// 4.  Finally, use a recurring appointment master object to specify
//     the recurrence information. Other appointment details such as
//     'subject' and 'location' are copied from the existing appointment
//     to the recurring appointment master object.

RecurringAppointmentMaster newRecurringAppointmentInfo = new RecurringAppointmentMaster
        StartTime = DateTime.Now.AddHours(2),
        EndTime = DateTime.Now.AddHours(3),
        RecurrencePatternType = new OptionSetValue(RecurrencePatternTypes.Weekly),
        Interval = 1,
        DaysOfWeekMask = DayOfWeek.Thursday,
        PatternStartDate = DateTime.Today,
        PatternEndType = new OptionSetValue(RecurrenceRulePatternEndType.Occurrences),
        Occurrences = 5

// Use the AddRecurrence message to convert the existing appointment
// object to a recurring appointment master object. The existing
// appointment object is deleted thereafter.

AddRecurrenceRequest recurringInfoRequest = new AddRecurrenceRequest
    Target = newRecurringAppointmentInfo,
    AppointmentId = _appointmentId

AddRecurrenceResponse recurringInfoResponse = (AddRecurrenceResponse)_serviceProxy.Execute(recurringInfoRequest);
__recurringAppointmentMasterId = recurringInfoResponse.id;

// Verify that the newly created recurring appointment master has same 'subject' 
// as the existing appointment.

RecurringAppointmentMaster retrievedMasterAppointment = (RecurringAppointmentMaster)_serviceProxy.Retrieve(RecurringAppointmentMaster.EntityLogicalName, __recurringAppointmentMasterId, new ColumnSet(true));
if (retrievedMasterAppointment.Subject == "Sample Appointment")
    Console.WriteLine("Sample Appointment is converted to a recurring appointment.");

Message Availability

This message works regardless whether the caller is connected to the server or offline.


Pass an instance of this class to the Execute method, which returns an instance of the AddRecurrenceResponse class.

Privileges and Access Rights

To perform this action, the caller must have privileges on the RecurringAppointmentMaster and Appointment entities, and access rights on the specified record in the Target property. For a complete list of the required privileges, see AddRecurrence Privileges.

Notes for Callers

When you convert an existing appointment to a recurring appointment by using this message, the data from the existing appointment is copied to a new recurring appointment master instance, and the existing appointment record is deleted.
