Overview of this book

To build a rich internet application, you need to integrate a powerful client side JavaScript framework with a server side framework. Ext.NET achieves this by integrating Sencha's Ext JS framework with the power of ASP.NET. The result ñ a sophisticated framework offering a vast array of controls, layout, and powerful AJAX and server bindings, which can be used to build rich, highly usable web applications. "Ext.NET Web Application Development" shows you how to build rich applications using Ext.NET. Examples guide you through Ext.NET's various components using both ASP.NET Web Forms and MVC examples. You will also see how Ext.NET handles data binding and server integration. You will also learn how to create reusable components and put them together in great looking applications. This book guides you through the various Ext.NET components and capabilities to enable you to create highly usable Ext.NET components and web applications. You will learn about various UI components and numerous layout options through examples. You will see how the AJAX architecture enables you to create powerful data-oriented applications easily. This book will also teach you how to create reusable custom components to suit your needs. "Ext.NET Web Application Development" shows you how to create rich and usable applications using Ext.NET through numerous examples.

Summary


Ext.NET offers many ways to make AJAX requests including:

  • DirectEvents

  • DirectMethods

  • Loader

We saw how seamless DirectEvents are, and how flexible DirectMethods can be to create a Remote Procedure Call like experience with minimal effort. We also saw that DirectMethods can be made static, which can boost performance. You can also create Ext.NET components during an AJAX request, on demand, which is very powerful for dynamic and responsive applications.

For even more flexible options, we noted that requests can be configured to use other services on your server by explicitly changing the URL. In doing so, we saw that some options, such as calling an ASMX service, can be flexible but has some caveats to consider. Calling ASHX-based services offers good performance but lacks the conventions that calling an ASMX or MVC Controller may provide. In addition, we saw that DirectMethods can be defined on User Controls and Master Pages, which offers further flexibility and reuse.
