TreeNodeBinding.Text Property

Gets or sets the text that is displayed for the node to which the TreeNodeBinding object is applied.

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

public string Text { get; set; }

Property Value

Type: System.String
The text displayed for the node to which the TreeNodeBinding object is applied. The default is an empty string ("").

When the TreeView control is bound to a data source, use the Text property to specify the value to bind to the Text property of a TreeNode object. This binding relationship affects all TreeNode objects to which the TreeNodeBinding object is applied. The Text property is used to specify the text displayed in a node.

NoteNote:

You can selectively override the Text property by setting the Text property of each node directly.

Instead of using the Text property to bind the same text to each node, you can bind the Text property of a TreeNode object to a field of a data source by setting the TextField property.

The value of this property is stored in view state.

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 section contains two code examples. The first code example demonstrates how to use the Text property to specify the value to display for a node to which the TreeNodeBinding object is applied. The second code example provides sample XML data for the first code example.

The following example demonstrates how to use the Text property to specify the value to display for a node to which the TreeNodeBinding object is applied. For this example to work correctly, you must copy the sample XML data, provided after this code example, to a file named Booklist.xml.
