Hello,
You can create relationship between Appointment and recurring Appointment.
Then use below code in your plugin/custom workflow to create recurring Appointment from c#
// Define an anonymous type to define the possible recurrence pattern values.
var RecurrencePatternTypes = new
{
Daily = 0,
Weekly = 1,
Monthly = 2,
Yearly = 3
};
// 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
};
// 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
};
// Create a recurring appointment
RecurringAppointmentMaster newRecurringAppointment = new RecurringAppointmentMaster
{
Subject = "Sample Recurring Appointment",
StartTime = DateTime.Now.AddHours(1),
EndTime = DateTime.Now.AddHours(2),
RecurrencePatternType = new OptionSetValue(RecurrencePatternTypes.Weekly),
Interval = 1,
DaysOfWeekMask = DayOfWeek.Thursday,
PatternStartDate = DateTime.Today,
Occurrences = 10,
PatternEndType = new OptionSetValue(RecurrenceRulePatternEndType.Occurrences)
};
_recurringAppointmentMasterId = _serviceProxy.Create(newRecurringAppointment);
Then You can add subgrid of RecurringAppointment on Appointment to show sub tasks.
Make sure you also set lookup field which got created from custom relationship.
