RSS (Rich Site Summary) news feeds are easily consumed and displayed in an ASP.NET web forms page using no more than a few lines of codes. However, listing the RSS news feed links in this fashion can take up considerable page space. Instead, it would be more convenient to display them in a small embedded window that automatically scrolls them to the user. This method substantially reduces the page real estate devoted to the news feed, while displaying the same information in a compact, attractive, and intuitive manner. Once you have developed a method for displaying RSS news in this format, it would be still more convenient to implement the method as a custom control that you can add to any ASP.NET web forms page with just a few lines of code. This article shows you how.
In this article, you will learn how to create the illusion of continuous seamless scrolling by: 1) using two datagrids to display the same listing; and 2) scrolling the entire total list, but then repeating the scrolling when it has passed over the first list.
