The default C1Calendar control displays a 7x6 calendar matrix for one calendar month. The seven columns represent the week days (Sunday through Saturday) and the six rows represent the weeks. You can change the number of calendar days shown on the calendar by increasing the integer values for the DayRows property.

In the default calendar you can select dates ranging from 1/1/1900 to 12/31/2099 since the minimum and maximum calendar date is set to these dates by default. Optionally, you can customize the selectable dates by specifying the date values for the MaxDate and MinDate properties.

The default control displays the dates for one calendar month at a time. Optionally, multiple calendar months can be displayed at a time by setting either the MonthCols or MonthRows to an integer value greater than one. For more information on multiple calendar views and their layout, see Multiple Calendar View.
