I believe you just set the Date or Value property. I don't remember which but:

MonthCalendar myCal = new MonthCalendar();

myCal.Date = new DateTime(01, 01, 2005);

The MonthCalendar control for the windows form does not have a Date property ?

So, i used the following :

this.monthCalendar1.TodayDate = new DateTime(01, 01, 2005);

but the monthcalendar did not switch to January ??

The highlighted date (and therefore the month) in the MonthCalendar control is determined by the

  MonthCalendar.SelectionRange property

    as in MonthCalendar1.SelectionRange.Start
    and   MonthCalendar1.SelectionRange.End

but Microsoft has kindly supplied these two properties as seperately as:

  MonthCalendar.SelectionStart and MonthCalendar.SelectionEnd

They can be set to the same date or to different dates (the MaxSelectionCount property determines the number of days that will be highlighted - default is 7)

MonthCalendar1.SelectionStart =  new DateTime(01, 01, 2005);
MonthCalendar1.SelectionEnd =  new DateTime(01, 01, 2005);

Hope this helps.

Hello,

I tried the setting of the SelectionStart and SelectionEnd,
but still the calendar do not refresh itself to show January.

?????  You would think that this would work, but i must be missing something ???

Once i set the selection range, how do i force the calendar to change ....

thanks

It does when I use the code I posted.

i must be missing something..
here is my code...

if (strCmd == "January")
{
 lnkJan.BorderStyle = BorderStyle.FixedSingle;
 monthCalendar1.SelectionStart = new DateTime(01, 01,2005);
 monthCalendar1.SelectionEnd = new DateTime(01, 01, 2005);
}

I also tried
monthCalendar.SelectionRange.Start
monthCalendar.SelectionRange.End...
and added a
monthCalendar1.Refresh();

the calendar currently displays the month of october...
but when i click on January, october is still displayed.

When i physically click on the previous, the day 01 is highlighted, so that works...but i need it to switch to display the month of Jan.

Can you send me your code ???

Thanks,

Its VB.Net but it shouldn't make any difference.

As you can see, I use two different methods to change the MonthCalendar, a DateTimerPicker's ValueChanged event and a Button's Click  event.

The DTP is used to change the MonthCalendar to the same date as the user selects in the DTP, whereas the Button changes the MonthCalendar to a specific date.

Hope this helps.
