Public Interface ICallbackContainer
Classes that implement the ICallbackContainer interface provide controls with a script that will initiate a callback to the server. A callback differs from the more common postback in that the page processing for the callback recreates the page without changing state information held by the page. For more information on creating callbacks, see Implementing Client Callbacks Without Postbacks.
