Server-centric Ajax Web DevelopmentIncremental approach to enrich UIDoesn’t require lots of JavaScriptKeep core logic on server (VB/C#)
Client-centric Ajax Web DevelopmentLeverage full power of script/DHTMLProvide richer and more interactive user experienceBuild mash-ups, gadgets and other new immersive experiences
<asp:UpdatePanel> controlEasily define “updatable” regions of a pageServer roundtrips become asynchronous ASP.NET AJAX handles all the infrastructureSupports 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>
Control ExtendersExtend ASP.NET controls with ASP.NET AJAX client behaviorsEncapsulate both client and server behaviorSame 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” />
UpdateProgress control provides feedback on the progress of partial-page rendering
<asp:UpdateProgress ID="UpdateProgress1“ runat="server"> <ProgressTemplate> Please Wait ... </ProgressTemplate></asp:UpdateProgress>
ASP.NET AJAX script core – a full type system for JavaScript
Classes, interfaces, inheritanceEnumerationsMulti-cast event handlers similar to .NET
Base class libraryStringBuilder, extensions to existing types SerializersDebugging and tracing classesNetworking
ScriptManager handles web service access
<asp:ScriptManager runat="server" ID="scriptManager"> <Services> <asp:ServiceReference path="~/WebServices/SimpleWebService.asmx" /> </Services> </asp:ScriptManager>
Server ASMX RequirementsReference to Microsoft.Web.Script.Services[ScriptService] Attribute on Class
Inline Methods on ASPX can be called as Web Services
Add [WebMethod] Attribute to Method
Shared-source, community projectSample controls and extendersSDK to simplify creating your own
