Client-side Events Overview
The RadCalendar controls support a number of client-side events that let you respond to user actions without a postback. The following table lists the various client events, and which controls they apply to:
Event | Description |
---|---|
OnDateSelected | Occurs immediately after the value of the control's selection has been changed. |
OnPopupOpening | Occurs immediately before a popup is displayed, before the selection in the popup is synchronized with the input area. |
OnPopupClosing | Occurs immediately before the a popup is closed. |
The embedded RadDateInput object that is used by RadDateTimePicker also has a number of client events. See the RadInput documentation for details.
To use these events, simply write a JavaScript function that can be called when the event occurs. Then assign the name of the JavaScript function as the value of the the corresponding property.
