HtmlControl.Attributes Property

Gets a collection of all attribute name and value pairs expressed on a server control tag within the ASP.NET page.

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

public AttributeCollection Attributes { get; }
/** @property */
public AttributeCollection get_Attributes ()

public function get Attributes () : AttributeCollection

Property Value

A System.Web.UI.AttributeCollection object that contains all attribute name and value pairs expressed on a server control tag within the Web page.

Use this property to programmatically access the attributes of the HTML server control. All HTML server controls store their attributes in the Control.ViewState property.

HTML attributes are treated by the .NET Framework as properties on the HTML server control to which they belong.

For additional information on the attributes collection, see the System.Web.UI.AttributeCollection class.

The following code example demonstrates how to use the Attributes property to determine the attributes of the HtmlSelect control.

<%@ Page Language="C#" AutoEventWireup="True" %>

<html>

<script language="C#" runat="server">
   void Page_Load(Object sender, EventArgs e) 
   {
      Message.InnerHtml = "<h4>The select box's attributes collection contains:</h4>";
     
      IEnumerator keys = Select.Attributes.Keys.GetEnumerator();

      while (keys.MoveNext()) 
      {

         String key = (String)keys.Current;
         Message.InnerHtml += key + "=" + Select.Attributes[key] + "<br>";

      }
   }

</script>

<body>

           runat="server">
