We suppose that you should get acquainted with the demo project first. This small application is designed to control roles and users and is represented as a lite version of the real administration system based on the classes from the System.Security namespace. To ensure normal operation of the sample below, you don’t have to setup database. That sample operates with the Books and News demo applications with already added roles and users. To see how it works please click here.

Download archive with the demo project and unpack it to any directory. Open the CallbackPageDemo.sln solution in VisualStudio 2005, compile it and see how the site works. As you can see, that is quite a standard application using standard components (except for the SoftAIN.GridView control, where the functionality of the System.Web.UI.WebControls.GridView base class is changed slightly). Let’s now add the AJAX functionality to the project.
