In this chapter, you will look at several Atlas applications and will dissect them to see how they work. In the process, you will glean lots of new information about how to use the Atlas extensions to ASP .NET to build powerful Ajax-style applications and how to extend your existing applications with asynchrony. At the end of the chapter, you will look into the reference application that was built by Microsoft for Atlas the Atlas wiki. This application demonstrates how you can put together a powerful and high-performing application using many of the Atlas techniques.

When the user clicks the button, called btnCopy, the function btnCopy_Click gets called. As you can see in this function, the values of the labels outside the UpdatePanel control get copied into the labels inside. This triggers a partial refresh on the page, where the server updates only the contents of those three labels. If you run the page, you ll see a screen like that in Figure 7-1. Typically in an application like this, if you click the button to change the value of the shipping address labels, the entire page will be posted to and from the server. As the page is rerendered, the entire page will blink as the browser deletes the current markup and replaces it with the new one. With Ajax, you could place the shipping address content within a named <div> element, and then the click of the button could make a call to a JavaScript function that does the copy and builds a new innerHTML property of that <div> element. Or, if the functionality was server side, it would generate a request on XMLHttpRequest and a callback for when the request is complete. The callback would then build HTML code to put on the innerHTML property of the named <div> element. The latter is exactly how the Atlas UpdatePanel control works under the hood. It uses Web.WebForms.PageRequestManager to set up an asynchronous callback. If you use an HTTP sniffer and run the page in Listing 7-1, you will see the following markup at the bottom of the page: <script type="text/javascript"> Web.WebForms.PageRequestManager._setupAsyncPostBacks( document.getElementById('form1'), 'ScriptManager1', ['UpdatePanel1'], []); </script> Barcode Recognizer In VS .NET Using Barcode Control SDK for ASP.NET Control to generate, create, read, scan barcode image in ASP.NET applications. www.OnBarcode.comBarcode Recognizer In None Using Barcode decoder for Software Control to read, scan read, scan image in Software applications. www.OnBarcode.comEncoding Barcode In Visual Studio .NET Using Barcode maker for Reporting Service Control to generate, create Barcode image in Reporting Service applications. www.OnBarcode.comGS1 - 12 Printer In None Using Barcode generation for Microsoft Excel Control to generate, create GS1 - 12 image in Microsoft Excel applications. www.OnBarcode.com |
