MenuItemBinding.TextField Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the name of the field from the data source to bind to the Text property of a MenuItem object to which the MenuItemBinding object is applied.

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

public string TextField { get; set; }
/** @property */
public String get_TextField ()

/** @property */
public void set_TextField (String value)

public function get TextField () : String

public function set TextField (value : String)

Property Value

The name of the field from the data source to bind to the Text of a MenuItem to which the MenuItemBinding is applied. The default is an empty string (""), which indicates that this property is not set.

When the Menu control is bound to a data source, use the TextField property to specify the name of the field to bind to the Text property of a MenuItem object. When rendered, the Text property of each menu item to which the MenuItemBinding object is applied contains the corresponding value from the field. This text is displayed in the menu items.

NoteNote

You can override the text for an individual menu item by setting its Text property directly.

If the data source contains multiple tables or attributes, you must first establish the binding criteria by setting the Depth property, the DataMember property, or both.

You cannot create empty nodes in a Menu control by setting the Text or TextField properties to the empty string (""). Setting these properties to the empty string has the same effect as not setting the properties. In that case, the Menu control creates a default binding using the DataSource property. For more information, see Web Page Data Binding Techniques.

Instead of using this property to bind the Text property of a MenuItem object to a field, you can also bind it to a static value by setting the MenuItemBinding.Text property. This allows you to display the same text in each menu item to which the MenuItemBinding object is applied.

NoteNote

If the Text and TextField properties are both set, the TextField property takes precedence.

The following code example demonstrates how to use the TextField property to specify the name of the field to bind to the Text property of a menu item. For this example to work correctly, you must copy the sample XML data below to a file named Menu.xml.
