chart image
  
The client side image map is updated on every auto refresh event. Right-click on the torus chart for a custom context menu. The exploded sector will still dislpay the default web browser menu as it has no interactivity style specified.

 
 
 
 
 
The "Rotate by 10 Degrees" button operation does not refresh the client-side image map. Use the "Force Update Image Map" button to get updated image map data.
 
 
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).
