AdRotator Control

This control is called an AdRotator because it is most often used to display advertisements on web pages. It displays an image randomly selected from a list stored either in a separate XML file or a data-bound data source. In either case, the list contains image attributes, including the path to the image and a URL to link to when the image is clicked. The image changes every time the page is loaded.

In addition to the properties inherited from WebControl, the AdRotator control has the properties and events listed in Table 5-10.
