Remarks

Each advertisement in the XML advertisement file can be assigned a category keyword. Use the KeywordFilter property to filter the advertisements for the specified keyword. Only advertisements containing the keyword will be selected for the AdRotator control. The KeywordFilter property can be programmatically set to match the profile of the user.

The KeywordFilter property is a very simple filter that searches for the specified keyword. It is not possible to specify more than one keyword in the KeywordFilter property, nor is it possible to declare multiple keywords in the advertisement file.

Note

The AdvertisementFile property needs to be set for this property to have any effect.

Caution

If the specified keyword is not found in the XML advertisement file, no advertisement is displayed in the AdRotator control. Be sure to specify a keyword for this property with at least one match in the advertisement file.
