MonthCalendar Class

Represents a Windows control that enables the user to select a date using a visual monthly calendar display.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class MonthCalendar extends Control

The MonthCalendar control allows the user to select a date using a visual display. You can limit the date and times that can be selected by setting the MinDate and MaxDate properties.

You can change the look of the calendar portion of the control by setting the ForeColor, Font, TitleBackColor, TitleForeColor, TrailingForeColor, and BackColor properties.


The DateTimePicker control only supports Gregorian calendars.

The MonthCalendar control is drawn by the operating system, so the Paint event is never raised. If you need to provide a customized look to the MonthCalendar control, you should override the OnPrint method, call the base implementation of OnPrint, and then perform custom painting.

If you need custom date formatting and a selection limited to just one date, you might consider using a DateTimePicker control instead of a MonthCalendar. Using the DateTimePicker eliminates much of the need for validating date/time values.

For more information on month calendar controls, see Month Calendar Control Reference.

The following code example displays a form containing a MonthCalendar control that displays one calendar year. The example demonstrates setting the BackColor, ForeColor, TitleBackColor, TitleForeColor, CalendarDimensions, and TrailingForeColor properties to customize the look of the calendar control. Other properties such as AnnuallyBoldedDates, BoldedDates, and MonthlyBoldedDates are set to customize which dates are bold. The example also sets the FirstDayOfWeek, MaxDate, MinDate, and MaxSelectionCount properties to change the calendar format. The DateSelected and DateChanged events are also handled and their status is displayed on the form.

No code example is currently available or this language may not be supported.
