Calendar / DayRender Event


Server Mode Calendar
Client Mode Calendar 		Selected date:


Selected day color:


Selected day text:


  • The demo illustrates how to utilize the DayRender server and client events of RadCalendar to customize the appearance of the rendered date. Note that in order to apply changes purely client-side attaching the DayRender client event, you need to navigate to a different month and thus force the calendar to re-render itself.
