<para>You must implement the <see cref="T:System.Web.UI.IPostBackDataHandler" /> interface when creating a server control that needs to examine form data that is posted back to the server by the client. The contract that this interface defines allows a server control to determine whether its state should be altered as a result of the postback, and to raise the appropriate events. For more information, see <format type="text/html"><a href="765bfc89-33ee-4d0d-bbe6-3b172c06def9">Server Event Handling in ASP.NET Web Pages</a></format>.</para>
