OnClientItemBlur
The OnClientItemBlur client-side event occurs when an item in the menu loses focus.
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 lost focus.
get_domEvent returns a reference to the DOM event that caused the blur.
You can use this event to respond when an item loses focus.
