System.Web.UI.HtmlControls   HtmlControl Class

---

Sets or retrieves a value indicating whether the Disabled attribute is specified when a server control is rendered.

Inline	<htmlcontrol disabled ... >
Script	HtmlControl.Disabled [ = true | false ]

This property accepts or returns only a boolean value: true if a control is disabled, and false if not.

This property is read/write with a default value of false.

Disabled is used to specify or determine whether a control is functional. When set ( to true ), the property has the following effects on a control:

• Disabled controls do not receive focus.
• Disabled controls are skipped in tabbing navigation.
• The data contained in a disabled control cannot be submitted with the form data set.

How disabled elements are rendered depends on the browser. In Microsoft^® Internet Explorer^® 4 and later, disabled controls appear dimmed and does not respond to user input.

NOTE: This property propagates down the control hierarchy. Hence, disabling a container control disables all child controls within that container.

The following example shows how to declaratively set the Disabled property of an HtmlControl at design time.

<input type=text id="myTextBox" disabled runat="server" />

The example below shows how to programmatically enable and disable an HtmlControl at run time, depending on the status of another control that is set by the user.

<script language="C#" runat="server">
void Page_Load ( object src, EventArgs e ) {
   myEmail.Disabled = join.Checked ? false : true;
}
</script>
