MonthCalendar.CalendarDimensions Property

Gets or sets the number of columns and rows of months displayed.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

[LocalizableAttribute(true)] 
public Size CalendarDimensions { get; set; }
/** @property */
public Size get_CalendarDimensions ()

/** @property */
public void set_CalendarDimensions (Size value)

public function get CalendarDimensions () : Size

public function set CalendarDimensions (value : Size)

Not applicable.

Property Value

A Size with the number of columns and rows to use to display the calendar.

Only one calendar year is displayed at a time, and the maximum number of months that can be displayed is 12. Valid combinations of columns and rows make a maximum product of 12; for values greater than 12, the display is modified on a best-fit basis.

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.
