Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

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 click on a link.

CAUTION   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 Controls.

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

Example

[Visual Basic, C#, JScript] The following example demonstrates how to use the ServerClick event to display a message when the HtmlAnchor is clicked.

[Visual Basic] 
<%@ Page Language="VB" AutoEventWireup="True" %>

<html>
   <script runat="server">
  
      Sub AnchorBtn_Click(sender As Object, e As EventArgs)

         ' Display a message when the HtmlAchor control is clicked.
         Message.InnerHtml = "Hello World!!"
      
      End Sub
  
   </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>
 

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

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

   <form runat="server">
  
      <h3> HtmlAnchor Control Example </h3>

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

</body>
</html>
 

[JScript] 
<%@ Page Language="JScript" AutoEventWireup="True" %>

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