System.Web.UI.HtmlControls Namespace

Allows programmatic access to the HTML <input type=hidden> element on the server.

You can use the HtmlInputHidden control to embed non-visible information within a <form> element. This information is sent when the Web page is posted back to the server.

The HtmlInputHidden control provides a ServerChange event that is raised when its Value property changes between posts to the server. This allows you to define a custom handler to perform some action each time the event is raised.

NOTE: The Web Forms page framework uses this HTML feature to automatically load and persist the view state of server controls on an ASP.NET page.

For examples illustrating use of this control, see the individual member types of this class. For syntax information, see HtmlInputHidden in ASP.NET Syntax for HTML Controls.
