Object Model
HttpHandlerImageRender Class
Syntax
'Declaration
 
Public Class HttpHandlerImageRender 
   Inherits ImageRender
   Implements IParallelSupportISparklineSupportHandler 
'Usage
 
Dim instance As HttpHandlerImageRender
public class HttpHandlerImageRender : ImageRender, IParallelSupportISparklineSupportHandler  
Remarks
HttpHandlerImageRender is recommended when charts are simple (easy to generate) or when you expect requests for a large number of different charts. HttpHandlerImageRender supplies two ways to save an image on the server, one is saving in HttpContext.Session and another is saving in HttpContext.Cache. An application developer can set the storage means by the ImageTransferStorage property and determine whether to hold the image data or clear it immediately after rendering by using the KeepTransferStorage property.
