The following code example demonstrates using the ImageUrlField property to specify a custom data field. The NavigateUrlField, ImageUrlField, and AlternateTextField properties are used to dynamically select a custom field to use in place of the NavigateUrl, ImageUrl, and AlternateText attributes. This example uses a device filter to indicate that custom fields should be used for Wireless Application Protocol (WAP)-enabled devices.

        devices. -->  
     <WmlImageUrl>~/Images/mobileAd1.jpg</WmlImageUrl>  
    <WmlNavigateUrl>https://msdn.microsoft.com/mobile/</WmlNavigateUrl>  
    <WmlAlternateText>Windows Mobile Developer Site</WmlAlternateText>

    <WmlAlternateText>Windows Mobile Developer Site</WmlAlternateText>  
  </Ad>  
</Advertisements>

Remarks

The ImageUrlField property is used for selecting a custom data field used in place of the ImageUrl attribute for an advertisement. Like ImageUrl, this custom field is defined in the XML file that contains advertisement information.
