Remarks
You must implement this method in a class derived from the ExpansionFunction class in order to provide a value for an expansion function. Your implementation of this method can call the GetArgument method to obtain values for any arguments the expansion function may have. Returning a null value indicates that the expansion function could not be evaluated (in which case the default value of the field is shown).
