DataAction.placeholderAsUrl Property
        
 Gets or sets a value indicating that the placeholder should be treated as a full URL instead of just a query string portion
 of the URL. This means that encoding will not be applied, which allows values like "http:somesite.com/" to be used as a value,
 or "http:[placeholder]" where placeholder is a valid URL.
