ListItem.Text Property

Gets or sets the text displayed in a list control for the item represented by the ListItem.

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

[PersistenceModeAttribute(PersistenceMode.EncodedInnerDefaultProperty)]
public string Text { get; set; }

Property Value

Type: System.String
The text displayed in a list control for the item represented by the ListItem control. The default value is String.Empty.

Use the Text property to specify or determine the text displayed in a list control for the item represented by the ListItem.

NoteNote

If the Text property contains null, the get accessor returns the value of the Value property. If the Value property, in turn, contains null, String.Empty is returned.

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.

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.


<!-- The following example demonstrates adding items to and removing items
from ListBox controls. When an item is selected in ListBox1, a new ListBoxItem with
the same value can be created and added to ListBox2, if ListBox2 does not already 
contain an item with that value. When the new ListBoxItem is created, it receives 
the Value property of the selected item as its Text property, and the Text property
of the selected item as its value property. -->
