The OnPopupClosing client-side event handler is called just before a popup calendar or time view is closed.

The event handler receives two arguments:

1. the object that fired the event.

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

Name	Return Type	Arguments	Description
get_popupControl()	RadTimeView or RadCalendar client-side object		Returns the client object for the time view or calendar that is about to close.

The following example uses the OnPopupClosing event to prevent the popup from closing if nothing is selected:

    <Calendar DayNameFormat="FirstLetter"
           UseColumnHeadersAsSelectors="False"
           UseRowHeadersAsSelectors="False">
    </Calendar>
    <ClientEvents OnPopupClosing="popupClosing" />
</telerik:RadDateTimePicker>		

JavaScript

function popupClosing(sender, eventArgs) {
	var popup = eventArgs.get_popupControl();
	
	if (popup == sender.get_calendar()) {
		if (popup.get_selectedDates().length == 0) {
			alert("You must select a date!");
			eventArgs.set_cancel(true);
		}
	}
	else if (!popup.getTime()) {
		alert("You must select a time!");
		eventArgs.set_cancel(true);
	}
}
