Example 1

The following example contains one form in an .aspx file. The form contains a AdRotator control that will rotate between three images:

<%@ Page Inherits="System.Web.UI.MobileControls.MobilePage"%> <%@ Register TagPrefix="Mobile" Namespace="System.Web.UI.MobileControls" Assembly="System.Web.Mobile" %> <Mobile:Form runat="server">   <Mobile:AdRotator runat="server"   AdvertisementFile="advertisements.xml" /> </Mobile:Form>

This is the ad file called "advertisements.xml":

<?xml version="1.0" ?> <Advertisements> <Ad> <ImageUrl>image1.gif</ImageUrl> <NavigateUrl>http://www.1.com</NavigateUrl> <AlternateText>Visit 1</AlternateText> </Ad> <Ad> <ImageUrl>image2.gif</ImageUrl> <NavigateUrl>http://www.2.com</NavigateUrl> <AlternateText>Visit 2</AlternateText> </Ad> <Ad> <ImageUrl>image3.gif</ImageUrl> <NavigateUrl>http://www.3.com</NavigateUrl> <AlternateText>Visit 3</AlternateText> </Ad> </Advertisements>
