Label Web Server Control
Displays static text on a Web Forms page and allows you to manipulate it programmatically.
<asp:Label id="Label1"
Text="label"
runat="server"/>
or
<asp:Label id="Label1"
runat="server">
Text
</asp:Label>
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.
CAUTION 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.
