<!-- The AdRotator control -->
<mobile:AdRotator id="AdControl" runat="server"
    ImageKey="MobileImgSrc" NavigateUrlKey="TargetUrl"
    AdvertisementFile="App_Data/ads.xml" Alignment="Left" 
    KeywordFilter="Developer" OnAdCreated="AdCreated_Event">
    <DeviceSpecific>
        <Choice Filter="isWML11" NavigateUrlKey="WmlTargetUrl" 
            ImageKey= "WmlImageSrc" />
    </DeviceSpecific>
</mobile:AdRotator>

<!-- The AdRotator control -->
<mobile:AdRotator id="AdControl" runat="server"
    ImageKey="MobileImgSrc" NavigateUrlKey="TargetUrl"
    AdvertisementFile="App_Data/ads.xml" Alignment="Left" 
    KeywordFilter="Developer" OnAdCreated="AdCreated_Event">
    <DeviceSpecific>
        <Choice Filter="isWML11" NavigateUrlKey="WmlTargetUrl" 
            ImageKey= "WmlImageSrc" />
    </DeviceSpecific>
</mobile:AdRotator>

Remarks

If the AdvertisementFile property has data and this KeywordFilter property has content, the AdRotator control selects an advertisement with a matching keyword.

If the AdvertisementFile property has data and this KeywordFilter property has content but there is no keyword match between this property and the file, a blank image displays and a trace warning is generated.
