Label Class
Assembly: System.Web (in system.web.dll)
[ControlValuePropertyAttribute(L"Text")] public ref class Label : public WebControl, ITextControl
/** @attribute ControlValuePropertyAttribute("Text") */
public class Label extends WebControl implements ITextControl
ControlValuePropertyAttribute("Text") public class Label extends WebControl implements ITextControl
Use the Label control to display text in a set location on the page. Unlike static text, you can customize the displayed text through the Text property.
You can also use the Literal and PlaceHolder controls to display text on the Web Forms page. However, unlike the Label control, these controls do not render any additional tags.

| 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. You can use validation controls to verify user input before displaying the input text in a control. ASP.NET provides an input request validation feature to block script and HTML in user input. For more information, see Securing Standard Controls, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Validating User Input in ASP.NET Web Pages. |
Accessibility
The markup rendered by default for this control might not conform to accessibility standards such as the Web Content Accessibility Guidelines 1.0 (WCAG) priority 1 guidelines. For details about accessibility support for this control, see ASP.NET Controls and Accessibility.
The following example demonstrates how to create a Label control on a Web page.
