MonthCalendar.DateSelected (Evento)

Se produce cuando el usuario selecciona una fecha de forma explícita mediante el mouse (ratón).

Espacio de nombres: System.Windows.Forms
Ensamblado: System.Windows.Forms (en system.windows.forms.dll)

public event DateRangeEventHandler DateSelected
/** @event */
public void add_DateSelected (DateRangeEventHandler value)

/** @event */
public void remove_DateSelected (DateRangeEventHandler value)

En JScript, se pueden controlar los eventos que define una clase, pero no se pueden definir unos propios.
No aplicable.

Este evento es similar a DateChanged, pero se produce al final de una selección de fecha realizada mediante el mouse. El evento DateChanged se produce durante cualquier selección de fecha, ya sea mediante mouse (ratón), teclado o código.

Para obtener más información sobre la forma de controlar eventos, vea Utilizar eventos.

En el ejemplo de código siguiente se muestra un formulario que contiene un control MonthCalendar que muestra un año del calendario. En el ejemplo se muestra cómo establecer propiedades como BackColor, ForeColor, TitleBackColor, TitleForeColor, CalendarDimensions y TrailingForeColor para personalizar la apariencia del control de calendario. Se establecen otras propiedades, como AnnuallyBoldedDates, BoldedDates y MonthlyBoldedDates, para personalizar las fechas que van a aparecer en negrita. En el ejemplo también se establecen las propiedades FirstDayOfWeek, MaxDate, MinDate y MaxSelectionCount para modificar el formato del calendario. También se controlan los eventos DateSelected y DateChanged y su estado se muestra en el formulario.
