Introduction
Use the System.Web.UI.WebControls.Literal control to reserve a location on the Web page to display text. The Literal control is similar to the Label control, except the Literalcontrol does not allow you to apply a style to the displayed text. You can programmatically control the text displayed in the control by setting the Text property.
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.
Example:
The following example demonstrates how to use the Literal control to display static text.
<%@ Page Language="C#" AutoEventWireup="True" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>Literal Example</title> <script runat="server"> void ButtonClick(Object sender, EventArgs e) { Literal1.Text="Welcome to ASP.NET!!"; } </script> </head> <body> <form id="form1" runat="server"> <h3>Literal Example</h3> <asp:Literal id="Literal1" Text="Hello World!!" runat="server"/> <br /><br /> <asp:Button id="Button1" Text="Change Literal Text" OnClick="ButtonClick" runat="server"/> </form> </body> </html>
