Part three in my Ajax JSP Controls series on IBM DeveloperWorks was published today. The URL for the article is: Building Ajax-enabled JSP TagLib controls, Part 3: Update panel and popup dialog box controls.

The article describes how to build two additional controls:

• Update panel—Asynchronously retrieves content to provide a dynamic user interface. The control provides configurable parameters for Cascading Style Sheets (CSS) formatting while content is being retrieved as well as post retrieval of content. It also provides standard event handlers (that is, before content is loaded, after the content is loaded) to allow for further customizations.
• Pop-up dialog—Provides a window that retrieves content asynchronously when the dialog is first shown. This provides a responsive user interface by retrieving content only upon demand. The control provides optional configurable parameters for CSS formatting, a dialog title, a close button located in top right corner of the window (similar to a standard Windows® dialog), and the dialog size and location.
