The method is implemented by types derived from DataControlField, such as TemplateField. This method is called to extract the values of two-way data-bound fields in the template to populate dictionaries to be passed to the data source for an update, insert, or delete operation. The field/value pair is stored in the dictionary collection that is passed to the method. The method is called by the ExtractRowValues method of data controls such as DetailsView and GridView.
