OnPopupOpening

The OnPopupOpening client-side event handler is called immediately before a popup time view is displayed.

The event handler receives two arguments:

1. the object that fired the event.

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

Name	Return Type	Arguments	Description
get_popupControl()	Time view client object		Returns the client object for the time view that is about to be displayed.
set_cancelCalendarSynchronization(value)		bool	Lets you prevent the popup control from synchronizing its value to the value in the input area.
set_cancel(value)		bool	Lets you prevent the popup from appearing.

The following example uses the OnPopupOpening event to initialize the selection if the input area is empty:

ASPNET

<telerik:RadTimePicker RenderMode="Lightweight" ID="RadTimePicker1" runat="server">
    <ClientEvents OnPopupOpening="popupOpening" />
</telerik:RadTimePicker>

JavaScript

function popupOpening(sender, eventArgs) {
	var popup = eventArgs.get_popupControl();
	var time = popup.getTime();;
	
	if (!time) {
		time = new Date();
		time.setHours(12);
		popup.setTime(time);
	}
}
