The OnDateClick client-side event handler is called when the user clicks on a date in the day matrix or presses the ENTER key while a date has focus. If the day is selectable, this event occurs before the OnDateSelecting event. If the day is not selectable (but in the valid range), this event occurs, but not the OnDateSelecting event.

The event handler receives two arguments:

  1. the RadCalendar object that fired the event.

  2. an event arguments object that exposes the following methods:OnDateClick event arguments object

Name Return Type Arguments Description
get_renderDay() RenderDay client-side object Returns the client-side RenderDay object that represents the day that was just clicked.
get_domEvent() DOM event object Returns the DOM event object for the mouse click event.
set_cancel(value) bool Lets you prevent the click from selecting the date that is clicked. However, even after calling set_cancel(true) , focus still moves to the clicked date.

The following example uses the OnDateClick event to confirm the selection of a date:

<telerik:RadCalendar RenderMode="Lightweight" ID="RadCalendar1" runat="server">
    <ClientEvents OnDateClick="confirmClick" />
function confirmClick(sender, eventArgs) {
    var day = eventArgs.get_renderDay();

    if (day.get_isSelectable()) {
        var date = day.get_date();
        var dfi = sender.DateTimeFormatInfo;
        var formattedDate = dfi.FormatDate(day.get_date(), dfi.ShortDatePattern);
        var confirmClick = confirm("Are you sure you want to " + (day.get_isSelected() ? "unselect " : "select ") + formattedDate + "?");
