The AdRotator control allows you display a
randomly selected image on a mobile page. Every time the page is
refreshed, a new image will be selected from the list specified in
the associated XML configuration file (referenced by the
AdvertisementFile property). The
AdRotator works in almost exactly the same manner
as the full-scale ASP.NET
System.Web.UI.WebControls.AdRotator web control,
using the same XML configuration file format, and raising the same
AdCreated event (which allows you to update other
parts of the mobile page to correspond with the dynamically selected
advertisement). The only significant difference is the addition of
the ImageKey property, which allows you to specify
an alternate image URL. For example, if you set
ImageKey to ImageUrl1, ASP.NET
will render the image specified by the
<ImageUrl1> element in the randomly selected
advertisement, instead of the image specified by the default
<ImageUrl> element. This gives you the
flexibility to create mobile pages that support multiple different
devices, each of which may require a different image format, by
adding multiple custom image URLs.
