Remarks
Use the Label control to display text in a set location on the page. Unlike static text, you can customize the displayed text by setting the Text property.
Warning
Text is not HTML encoded before it is displayed in the Label control. This makes it possible to embed script within HTML tags in the text. If the values for the control come from user input, be sure to validate the values to help prevent security vulnerabilities.
For detailed information on the Label Web server control's properties and events, see the Label class documentation.
Example
The following example demonstrates how to create a Label control on a Web page.
Note
The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Page Code Model.
