ASP.NET FAQ - AdRotator

Here is an article from ftp online: Create a MultiRotator Server Control

Use namespace System.Xml

VB.NET

Dim xmlDoc As New XmlDocument
xmlDoc.Load(Server.MapPath(AdRotator1.AdvertisementFile))
Dim imgArrList As New ArrayList
Dim xmlNode As XmlNode
For Each xmlNode In xmlDoc.SelectNodes('/Advertisements/Ad/ImageUrl')
	imgArrList.Add(xmlNode.InnerText)
Next 

C#

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath(AdRotator1.AdvertisementFile));
ArrayList imgArrList = new ArrayList();
foreach (XmlNode xmlNode  in xmlDoc.SelectNodes('/Advertisements/Ad/ImageUrl'))
{
	imgArrList.Add(xmlNode.InnerText);
}

If the KeywordFilter property of the AdRotator control is set to a keyword that does not correspond to any element in the Advertisement file then you may get a blank image.
Here is some code that should work properly.

<asp:AdRotator id='AdRotator1' AdvertisementFile='adrot.xml' 
	runat='server' Width='468px' KeywordFilter ='book' Height='60px'></asp:AdRotator>

adrot.xml
