HtmlControl.Disabled Property

Gets or sets a value indicating whether the HTML server control is disabled.

Namespace:  System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

public bool Disabled { get; set; }
<asp:HtmlControl Disabled="True|False" />

Property Value

Type: System.Boolean
true if the control is disabled; otherwise, false. The default value is false.

In the browser, a disabled element or control is read-only, with the following added restrictions: its value is not submitted with the form, the element or control cannot receive focus, and the element or control is skipped when navigating the document by tabbing.

The following code example demonstrates how to use the Disabled property to programmatically enable and disable an HtmlInputButton control.

      void Submit_Clicked(Object sender, EventArgs e) 

         Message.InnerHtml = "You clicked the submit button.";


      void Enable_Clicked(Object sender, EventArgs e) 

         Message.InnerHtml = "";



   <form id="form1" method="post" runat="server">
