Recurrence Exception Doesn't Work

[Gary]

Followed is my code used to test recurrence exception functionality. I could never get it to work. The grid shows the appointment occurrences correctly. Hello World recurs exactly 4 time starting from today. However the first recurrence exception doesn't work. I wonder if you guys can provide us a simple code how to create an exception for occurrences.

List<Appointment> lstAppt = new List<Appointment>();
            Appointment objAppt;
            objAppt = new Appointment();
            objAppt.Start = DateTime.Now;
            objAppt.End = DateTime.Now.AddHours(1);
            objAppt.Description = "Hello World";
            objAppt.ID = 1;
            objAppt.RecurrenceParentID = 1;

            RecurrenceRange objRange = new RecurrenceRange();
            objRange.Start = DateTime.Now;
            objRange.RecursUntil = DateTime.Now.AddDays(4);//add 4 reccurence for today


            DailyRecurrenceRule objDailyRecurrenceRule = new DailyRecurrenceRule(RecurrenceDay.EveryDay, objRange);
            objDailyRecurrenceRule.Exceptions.Add(DateTime.Now);//add 1  exception for the first recurrence




            objAppt.RecurrenceRule = objDailyRecurrenceRule.ToString();


            lstAppt.Add(objAppt);


            objAppt = new Appointment();
            objAppt.Start = DateTime.Now.AddHours(3);
            objAppt.End = DateTime.Now.AddHours(4);
            objAppt.Description = "Good Bye";
            objAppt.ID = 2;
            objAppt.RecurrenceParentID = 2;
            lstAppt.Add(objAppt);


            RadScheduler1.DataSource = lstAppt;
            RadScheduler1.DataBind();

Hello Gary,

It seems that the problem was that the time you were trying to set for the first recurrence exception was different from the one at the appointment. Here is the code that should work for you:

List<Appointment> lstAppt = new List<Appointment>();
      Appointment objAppt;
      objAppt = new Appointment();
      objAppt.Start = DateTime.Now;
      objAppt.End = DateTime.Now.AddHours(1);
      objAppt.Description = "Hello World";
      objAppt.ID = 1;
      objAppt.RecurrenceParentID = 1;

      RecurrenceRange objRange = new RecurrenceRange();
      objRange.Start = objAppt.Start;
      objRange.RecursUntil = DateTime.Now.AddDays(4);//add 4 reccurence for today


      DailyRecurrenceRule objDailyRecurrenceRule = new DailyRecurrenceRule(RecurrenceDay.EveryDay, objRange);
      objDailyRecurrenceRule.Exceptions.Add(objAppt.Start);//add 1  exception for the first recurrence

The problem that you experience was most likely caused by the fact that DateTime.Now has different value for each line of code (even though infinitesimally small, that difference still matters).
