ASP.NET AJAX is a framework that allows for building richer web applications with more interactive and personalized experiences. It provides tools for asynchronous partial page updates, extending controls with new client-side behaviors, and a full JavaScript class library. Developers can take either a server-centric or client-centric approach to building AJAX applications using ASP.NET AJAX.

Introduction To Asp.Net Ajax
- 1. Jeff Blankenburg Developer Evangelist Microsoft Corporation http://www.jeffblankenburg.com [email_address]
- 2. Increased productivity Fewer concepts, fewer lines of code Easier to author, debug, and maintain Well integrated with design and development tools Seamlessly integrated application model Works with ASP.NET pages and server controls Works everywhere – cross-browser, standards based A framework for building richer, more interactive, more personalized web experiences.
- 3. Server Framework Client Framework and Services Client Application Services Browser Integration ASP.NET AJAX ASP.NET Pages Web Services HTML, Script, ASP.NET AJAX Markup Service Proxies ASP.NET AJAX Server Extensions ASP.NET AJAX Server Controls App Services Bridge Web Services Bridge Client Script Library Controls, Components Script Core Base Class Library Component Model and UI Framework Browser Compatibility ASP.NET 2.0 Application Services Page Framework, Server Controls
- 4. Server-centric Ajax Web Development Incremental approach to enrich UI Doesn’t require lots of JavaScript Keep core logic on server (VB/C#) Client-centric Ajax Web Development Leverage full power of script/DHTML Provide richer and more interactive user experience Build mash-ups, gadgets and other new immersive experiences
- 5. <asp:UpdatePanel> control Easily define “updatable” regions of a page Server roundtrips become asynchronous ASP.NET AJAX handles all the infrastructure Supports Triggers that allow other controls to fire the Postback <asp:UpdatePanel id=“updatepanel1” runat=“server”> <ContentTemplate> <!-- This content will be dynamically updated! --> <asp:Calendar id=“calndr1” runat=“server”/> <ContentTemplate> </asp:UpdatePanel>
- 6. Control Extenders Extend ASP.NET controls with ASP.NET AJAX client behaviors Encapsulate both client and server behavior Same familiar programming model as ASP.NET server controls <asp:TextBox runat="server" ID="TextBox1" /> <asp:AutoCompleteExtender runat="server" ID="AC1” TargetControlID="TextBox1" ServicePath="AutoComplete.asmx“ ServiceMethod="GetWords” />
- 7. UpdateProgress control provides feedback on the progress of partial-page rendering <asp:UpdateProgress ID="UpdateProgress1“ runat="server"> <ProgressTemplate> Please Wait ... </ProgressTemplate> </asp:UpdateProgress>
- 8. ASP.NET AJAX script core – a full type system for JavaScript Classes, interfaces, inheritance Enumerations Multi-cast event handlers similar to .NET Base class library StringBuilder, extensions to existing types Serializers Debugging and tracing classes Networking
- 9. ScriptManager handles web service access <asp:ScriptManager runat="server" ID="scriptManager"> <Services> <asp:ServiceReference path="~/WebServices/SimpleWebService.asmx" /> </Services> </asp:ScriptManager> Server ASMX Requirements Reference to Microsoft.Web.Script.Services [ScriptService] Attribute on Class Inline Methods on ASPX can be called as Web Services Add [WebMethod] Attribute to Method
- 10. Shared-source, community project Sample controls and extenders SDK to simplify creating your own Full source code & documentation ~30 controls and components
