In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
The MenuItemDataBound event is raised when a menu item is bound to data in a Menu control. This allows you to provide an event handler that performs a custom routine, such as adding custom content or modifying a menu item before it is rendered, whenever this event occurs.
A MenuEventArgs object is passed to the event handler, which allows you to access the properties of the menu item that raised the event.
For more information about handling events, see Consuming Events.
The following code example demonstrates how to create an event handler for the MenuItemDataBound event that modifies the text of the Home menu item before it is displayed in a Menu control.
