<para>You can use the <see cref="T:System.Web.UI.HtmlControls.HtmlInputHidden" /> control to embed information that is hidden from the user within a <form> element. This information is sent when the Web page is posted back to the server. The <see cref="T:System.Web.UI.HtmlControls.HtmlInputHidden" /> control provides a <see cref="E:System.Web.UI.HtmlControls.HtmlInputHidden.ServerChange" /> event that is raised when the <see cref="P:System.Web.UI.HtmlControls.HtmlInputControl.Value" /> property changes values between posts to the server. This allows you to create an event handler that performs a custom set of instructions each time the event is raised.</para>
