Now that you have had a chance to explore master pages and site-navigation controls, you will learn about another control from the Standard group in the Toolbox task pane: the AdRotator control. This control uses the information in an XML file to display advertising banners in a page.
In this case, you will add the banner to the master page in order to ensure that the banner is displayed in all the pages in your site that are attached to it. You will put the banner inside of the ContentPlaceHolder control of the master page so that a user can change it on a page-by-page basis.
In this exercise, you will insert an ASP.NET AdRotator control and modify the XML file that provides the information to display the ads.
