| HtmlInputHidden | disposable |
| System.Web.UI.HtmlControls (system.web.dll) | class |
This class represents the HTML <input
type=hidden> tag, which allows you to store hidden
information that will be sent with all postbacks. This technique is
commonly used to store information without using cookies or session
state. ASP.NET automatically uses a hidden input field to preserve
the contents of server controls that have the
System.Web.UI.Control.EnableViewState property set
to True.
You can also react to the ServerChange event.
Because the hidden input field will be changed only through code on
the server, this event will fire immediately in response to changes
implemented by your code.
