4. Using Server-side ASP.NET AJAX Ajax Vision – Reduce full postback of ASP.NET – Google docs, suggest, gmail – An Ajax Application is a client-side web application written using native browser technologies such as JavaScript and DOM. – A pure Ajax application is a web application that consists of a single page and performs all its communications with the web server through web service calls. – In an Ajax application, the user interface layer is located in the browser (where it should be). The business logic and data access layers are located on the server. The user interface layer accesses the business logic layer through web services.

5. Using Server-side ASP.NET AJAX (Continue…) Server-Side Ajax versus Client-Side Ajax – Microsoft has both server-side Ajax framework and client-side Ajax framework. – Server-side Ajax framework is to provide existing ASP.NET developers with an easy way to implement Ajax functionality. – Client-side Ajax framework is to provide web developers with the tools they need to build pure client-side Ajax applications. – Advantages of server-side: provides existing ASP.NET developers with a painless method of doing Ajax. – Disadvantages of server-side: it doesn’t escape all the problems associated with a server-side framework. – Advantages of client-side: build very rich and responsive web applications. – Disadvantages of client-side: currently not fully baked.

37. ASP.NET AJAX Controls & Extenders Important ASP.NET AJAX Classes and Interfaces Bina Nusantara References: ProASP.NET 3.5 Server Controls and AJAX Components(Rob Cameron and Dale Michalk, 2008) Base ClassDescription ExtenderControlThis is the abstract base class implemented when creating an ASP.NET AJAX extender control. This class inherits from Control and implements IExtenderControl. IExtenderControlImplement this interface to build an extender control that does not require a ScriptManager. The IExtenderControl interface registers the script libraries for a control by calling the GetScriptReferences() method, and it registers ScriptDescriptor objects by calling the GetScriptDescriptors(Control) method. IScriptControlImplement this interface to add ASP.NET AJAX support to a custom server control. The methods of the IScriptControl interface provide references to script libraries that define client components and script descriptors that represent instances of client types required to add script control functionality in an ASP.NET Server control. It’s found in the System.Web.UI namespace. ScriptControlThis is the abstract base class implemented when creating an ASP.NET server control that includes ASP.NET AJAX functionality. This class inherits from WebControl and implements IScriptControl. ScriptReferenceThis class registers an ECMAScript (JavaScript) file for use on a web page.

38. ASP.NET AJAX Controls & Extenders ASP.NET AJAX-Related Namespaces Bina Nusantara References: ProASP.NET 3.5 Server Controls and AJAX Components(Rob Cameron and Dale Michalk, 2008) NamespaceDescription System.Web.ConfigurationThis namespace is extended by ASP.NET AJAX to support declarative and programmatic access to ASP.NET AJAX configuration elements. Example classes are ScriptingJsonSerializationSection and ScriptingSectionGroup. System.Web.Script.SerializationThis namespace was added to ASP.NET to support JavaScript Object Notation (JSON) serialization as well as provide extensibility features to customize serialization. System.Web.Script.ServicesThis namespace was added to ASP.NET to provide attributes for customizing web service support in ASP.NET AJAX. Example classes are ScriptServiceAttribute and ScriptMethodAttribute. System.Web.UIThis namespace is extended by ASP.NET AJAX to provide classes and interfaces that enable client-server communication and rich UI. Example classes are ExtenderControl, ScriptControl, and UpdatePanel. System.Web.UI.DesignThis namespace is extended by ASP.NET AJAX to provide designtime support for Microsoft ASP.NET AJAX. Example classes are UpdatePanelDesigner, TimeDesigner, and UpdateProgressDesigner. System.Web.HandlersThis namespace is extended by ASP.NET AJAX to provide the necessary HTTP handler (ScriptResourceHandler) and HTTP module (ScriptModule) to support ASP.NET AJAX.
