RecurenceRule .ToString is screwed up.

[Albert]

I added Exceptions trough RecurrenceRule.Exceptions.Add, but when I use the ToString, the EXDATEs are off by a day.

This is my Exceptions collection,

2/21/2009
2/24/2009
3/7/2009
3/13/2009
3/20/2009
3/27/2009

but the resulting string is

DTSTART:20090213T160000Z
DTEND:20090213T160000Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,FR
EXDATE:20090220T160000Z,20090223T160000Z,20090306T160000Z,20090312T160000Z,20090319T160000Z,20090326T160000Z

Hello Albert,

Please, try setting TimeZoneOffset="00:00:00". Let us know if the problem still persists.

I doubt the will help seeing as the timezoneoffset is a property of the RadScheduler, not the RecurrenceRule. Anyways, tried it and no it is still the same result

Hi Albert,

Can you send us the code of your implementation, please?

{
RecurrenceRule RecRule = (RecurrenceRule)new MonthlyRecurrenceRule(0, new RecurrenceRange());

.... Some code to get frequency, interval, etc. from database

RecRule = AddExceptionstoRule(RecRule, myCal.id);
string RRule = RecRule.ToString();
//Everything is correct except for the EXDATE string which has hours/days that are off by an hour/day
}

 private RecurrenceRule AddExceptionstoRule(RecurrenceRule RecRule, long CalendarID)
    {       
        List<fnbl_pim_calendar_exception> CalendarExceptionCollection = GetCalendarExceptionCollection(CalendarID);
        foreach (fnbl_pim_calendar_exception myCalEx in CalendarExceptionCollection)
            RecRule.Exceptions.Add(myCalEx.occurrence_date);
        return RecRule;
//values in collection are
//2/21/2009
//2/24/2009
//3/7/2009
//3/13/2009
//3/20/2009
//3/27/2009
}

Hello Albert,

Thank you for sending us the sample code. The problem seems to be that the exception dates are being supplied in Local time. The recurrence-related classes require that dates are UTC. Specifying the type should solve the problem:

DateTime.SpecifyKind(myCalEx.occurrence_date, DateTimeKind.Utc);

We'll consider making this requirement optional and/or state this more clearly in the documentation. I'm sorry for the inconvenience.

Sincerely yours,
