Building Interactive User Interfaces with Microsoft ASP.NET AJAX: Rebinding Client-Side Events After a Partial Page Postback
The UpdatePanel is the workhorse of the ASP.NET Ajax library. It is responsible for defining regions of a web page that trigger partial page postbacks (as opposed to full page postbacks). Such partial page postbacks transfer less information between the client and server and have their user interfaces updated seamlessly, thereby leading to a more interactive user experience. (For more information on UpdatePanels, refer to Using the UpdatePanel.) One side-effect of a partial page postback is that the HTML elements within the UpdatePanel are replaced with the markup returned on postback. This behavior is not noticeable and is not an issue unless you have client-side event handlers wired up to the
Displaying Files and Folders in a GridView
The .NET Framework provides a variety of classes in the System.IO namespace that simplify working with the file system. Using these classes it's possible to delete files and folders, to create new files, to edit existing files, and more.

Implementing the Store Locator Application Using ASP.NET MVC (Part 1)
Back in May 2010 I wrote a three-part article series titled Building a Store Locator ASP.NET Application Using Google Maps API, which showed how to build a simple store locator application using ASP.NET and the Google Maps API. The application consisted of two ASP.NET pages. In the first page, the user was prompted to enter an address, city, or postal code (screen shot). On postback, the user-entered address was fed into the Google Maps API's geocoding service to determine whether the address, as entered,
