HtmlAnchor Class

Allows programmatic access to the HTML <a> element on the server.

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

public class HtmlAnchor : HtmlContainerControl, IPostBackEventHandler
public class HtmlAnchor extends HtmlContainerControl implements IPostBackEventHandler
public class HtmlAnchor extends HtmlContainerControl implements IPostBackEventHandler

There are two ways to use the HtmlAnchor class. The first is for navigation: using the HRef property to define the location of the page to link to. The second is for postback events: using the ServerClick event to programmatically handle the user's clicking a link.

Caution noteCaution

This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. ASP.NET provides an input request validation feature to block script and HTML in user input. Validation server controls are also provided to assess user input. For more information, see Validation Server Control Syntax.

For a list of initial property values for an instance of HtmlAnchor, see the HtmlAnchor constructor.

The following code example demonstrates how to use the ServerClick event to display a message when the HtmlAnchor control is clicked.

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

<html>
   <script runat="server" >
  
      void AnchorBtn_Click(Object sender, EventArgs e)
      {
         // Display a message when the HtmlAnchor control is clicked.
         Message.InnerHtml = "Hello World!";
      }
  
   </script>
  
<body>

   <form runat="server">
  
      <h3> HtmlAnchor Control Example </h3> 
  
      <a ID="AnchorButton"
         OnServerClick="AnchorBtn_Click" 
         runat="server">
 
         Click here

      </a>
   
      <h1>
         <span id="Message" runat="server"/>
      </h1>
  
   </form>

</body>
</html>
