CallbackPage is the easiest way to include AJAX functionality in your web sites. A project is developed as an usual ASP.NET application, using standard VisualStudio and/or third-party components. All you need to transform the site to an AJAX application is to define blocks to upload after the users' acts and customize the templates. The result application will look for any user as an usual web site - with correct behaviour of Back and Forward buttons and static links. But the site won't be reloaded after each request to the server. Only necessary part of a page will be updated.

ViewStatePage is a class inherited from System.Web.UI.Page that implements saving the values of the _ViewState hidden field in database or file on a disk. The use of this class allows for considerably reducing traffic between a browser and server provided that you use ASP.NET technologies. At the same time, a number of control elements located on a _ViewStatePage class page-heir does not change the finite size of the _ViewState field. This allows for using any compound classes such as DataGrid that keep their current state in this field.
