Client-side Programming Overview
The RadNotification object provides a client-side API that lets you interact with the control in client-side code. In addition to a full set of client-side events, the client-side object model lets you manipulate notifications while avoiding unnecessary post-backs.
Getting the RadNotification client-side object
The RadNotification creates a client-side object with the ClientID of the control. You can obtain the reference to this object by using the following JavaScript code:
var radNotification1 = $find("<%= RadNotification1.ClientID %>");
Cancelling an Action
Some client-side events occur immediately before RadNotification performs some action. You can use these events to cancel the impending action by using the cancel property of the eventArgs passed to the handler:
function OnClientShowing(sender, eventArgs)
{
eventArgs.set_cancel(true);
}
