I have encountered a strange occurance in the calendar control. Not sure if it is something I have done or not.
Here is the piece of code I am using
public void RefreshMonth()
{
addDebug("Running Refresh Display");
//reset calendar formatting
this.MonthView.WeeksCount = weeksInMonth(_CurrentDate);
addDebug("-- Set display to "+weeksInMonth(_CurrentDate)+" weeks");
addDebug("---- Confirm "+this.MonthView.WeeksCount+" weeks");
addDebug("-- Redrawing control");
//update all events
addDebug("-- Removing all events");
this.DataProvider.RemoveAllEvents();
CalendarDataProvider pCalendarData = this.DataProvider;
pCalendarData.Create();
addDebug("-- Creating events for "+this.ActiveView.DaysCount+" days");
for(int i=0; i<this.ActiveView.DaysCount; i++)
{
CalendarViewDay cvd = this.ActiveView;
addDebug("--- Checking "+cvd.Date.ToShortDateString());
if(cvd.Date.Month != _CurrentDate.Month)
continue;
int day = cvd.Date.Day;
int index = day-1;
double data = Convert.ToDouble(_dataStore[index]);
addDebug("--- Adding event for day "+day+" - "+data+" hours");
CalendarEvent ptrEvent = pCalendarData.CreateEvent();
ptrEvent.StartTime = cvd.Date;
DateTime dtNow = cvd.Date;
ptrEvent.StartTime = dtNow;
dtNow = dtNow.AddDays(1);
ptrEvent.EndTime = dtNow;
ptrEvent.Subject = Convert.ToString(data);
ptrEvent.AllDayEvent = true;
ptrEvent.Location = "Hrs";
ptrEvent.Label = 0;
pCalendarData.AddEvent(ptrEvent);
}
addDebug("-- Populating Data");
pCalendarData.Save();
this.Populate();
//do final update
addDebug("-- Updating control");
this.Update();
}

Now this all works fine except in one situation.
Lets say the calendar is showing August 2005 (which has 5 week rows in the calendar) and I change to October 2005 (which has 6).
What occurs is that CalendarViewDay's on the 6th row of the calendar dont seem to return correctly in the following line.
CalendarViewDay cvd = this.ActiveView;
cvs.Date is always set to 30/12/1899
In my code this results in the two events that should be created on that 6th line, to not be created.
However, if I then run the exact same function again, immediately after the failed attempt, it works fine.
My question is...
I am quite new to these controls so it is quite possible I am not doing something correctly... Is it my code (or something i have done) or is it a bug?

this.MonthView.WeeksCount = weeksInMonth(_CurrentDate);

When you change MonthView.WeeksCount - you have to call Populate method first to adjust calendar view days collection. (should be done before accesssing ActiveView members)
this.DataProvider.RemoveAllEvents();
this.Populate();
