Implements

ITextControl.Text

Use the Text property to specify or determine the text content of the Label control. This property is commonly used to programmatically customize the text that is displayed in the Label control. The Text property can include HTML.

NoteNote:

Setting the Text property will clear any other controls contained in the Label control.

Security noteSecurity Note:

This control can be used to display user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and ASP.NET Globalization and Localization.

This property is the default property that a ControlParameter object binds to at run time. For more information, see ControlValuePropertyAttribute, ControlParameter, and Using Parameters with Data Source Controls.

The following example demonstrates how to create a new instance of the Label control and set its Text property.

NoteNote:

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.
