WebForms DateInput Overview

RadDateInput is an input control that formats and validates DateTime values, and and has 'smart' parsing engine which recognizes whether the user entry can be converted to DateTime format or not. It shares the common properties of all RadInput controls, including support for skins, styles for different states, empty message support, conditional postback on date change, labels, and so on.
