OnPopupClosing
The OnPopupClosing client-side event handler is called just before a popup calendar or time view is closed.
The event handler receives two arguments:
the object that fired the event.
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. | |
| set_cancel(value) | bool | Lets you prevent the popup from closing. |
The following example uses the OnPopupClosing event to prevent the popup from closing if nothing is selected:
<telerik:RadDateTimePicker RenderMode="Lightweight" ID="RadDateTimePicker1" runat="server">
<Calendar DayNameFormat="FirstLetter"
UseColumnHeadersAsSelectors="False"
UseRowHeadersAsSelectors="False">
</Calendar>
<ClientEvents OnPopupClosing="popupClosing" />
</telerik:RadDateTimePicker>
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);
}
}
