Set Event Handlers via JavaScript

Aside from declaring an event handler in the server-side properties of the RadNotification you can also assign them in client-side code. When using the client-side API, pass a reference to the event handler rather than its name. One advantage of using the client-side API is that you can attach multiple event handlers to one event using the standard MS AJAX convention:

JavaScript

function addEvents()
{
    var radNotification1 = $find("<%= RadNotification1.ClientID %>");
    radNotification1.add_shown(clientShown1);
    radNotification1.add_shown(clientShown2);
}

Another advantage of the client-side API is that you can detach an event handler dynamically:

JavaScript

function removeEvents()
{
    var radNotification1 = $find("<%= RadNotification1.ClientID %>");
    radNotification1.remove_shown(clientShown1);
}
