ICallbackContainer Interface

Note: This interface is new in the .NET Framework version 2.0.

Defines a method that enables controls to obtain a callback script.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public interface ICallbackContainer
public interface ICallbackContainer
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 in ASP.NET Web Pages.

Classes that implement the ICallbackContainer interface should also implement the ICallbackEventHandler interface to handle the events raised by controls.
