OnClientItemClosed
The OnClientItemClosed client-side event occurs immediately after an item in the menu contracts to hide its child items.
The event handler receives two parameters:
The instance of the menu firing the event.
An eventArgs parameter containing the following method:
get_item returns a reference to the RadMenuItem that was closed.
get_domEvent returns a reference to the DOM event that caused the closing.
You can use this event to respond when the list of child items closes.
<script type="text/javascript">
function ItemClosed(menu, args) {
alert("Closing " + args.get_item().get_text());
}
</script>
