public class DateRangeEventArgs extends EventArgs

El evento DateChanged tiene lugar cuando cambia la fecha o el intervalo de fechas seleccionado actualmente; por ejemplo, cuando el usuario cambia de forma explícita una selección dentro del mes actual o cuando la selección cambia de manera implícita como respuesta a la exploración de mes siguiente/anterior. El evento DateSelected se produce cuando el usuario cambia una selección de forma explícita. El constructor DateRangeEventArgs especifica el inicio y el final del nuevo intervalo de fechas seleccionado.

dczy9fe5.alert_note(es-es,VS.90).gifNota:

Si se selecciona una sola fecha, los valores de las propiedades Start y End serán iguales.

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

En el siguiente ejemplo 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 propiedades para modificar el formato del calendario, entre las que se incluyen FirstDayOfWeek, MaxDate, MinDate y MaxSelectionCount. Los eventos DateSelected y DateChanged también se controlan y su estado se muestra en el formulario.
