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.

- 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” />
