Label.Text Property

Gets or sets the text content of the Label control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[BindableAttribute(true)]
[PersistenceModeAttribute(PersistenceMode.InnerDefaultProperty)]
public virtual string Text { get; set; }
<asp:Label Text="String" />

Property Value

Type: System.String
The text content of the control. The default value is String.Empty.

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. If it does, the HTML will be passed unchanged to the browser, where is might be interpreted as markup and not as text. If you want the browser to display HTML markup as plain text, you can use the HtmlEncode method, as shown in the example for the class overview. You can also use the Literal control instead of the Label control, and set the Mode property to Encode.

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 for Filtering.

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 Forms Page Code Model.
