		The client side image map is updated on every auto refresh event. Right-click on the rotating shapes or the "sun" for a custom context menu.

This example demonstrates how custom commands and return data can be used. Custom commands are provided to allow the developer to execute callback requests synchronously to a specific web control. Return data is useful when feedback from the server has to be acquired. The feedback is received by the client script as a chunk of XML that is parsed and accessed through the NAjaxXmlTransport JavaScript class. Custom return data can be provided by the server for both custom and built-in commands (like refresh and mouse move event commands).
