The FooterStyle property governs the appearance of any text displayed in the footer item of a type derived from DataControlField.
Some data-bound controls do not render a footer item for a data control field. For example, the DetailsView control displays its data control fields as rows. A footer item is not rendered for these data control fields. The FooterStyle property is ignored in these controls.
