Modifying Functionality Using a Custom Event

An event is a specific user action like pivoting, sorting, and so on. An event handler determines how the requested action, or event, is processed. You can customize events and event handlers easily by performing the following:

• Build New Functionality: Create a new event and extend the event handler to process the new event.  

• Modify Default Functionality: Create a custom event handler to process an event differently. You can either extend an existing event handler or you can create a new event handler.
