MenuItemBinding.Value Property
Assembly: System.Web (in system.web.dll)
[LocalizableAttribute(true)] public: property String^ Value { String^ get (); void set (String^ value); }
/** @property */ public String get_Value () /** @property */ public void set_Value (String value)
public function get Value () : String public function set Value (value : String)
Property Value
Supplemental data about a menu item to which the MenuItemBinding is applied; this data is not displayed. The default value is an empty string (""), which indicates that this property is not set.When the Menu control is bound to a data source, use the Value property to specify the value to bind to the MenuItem.Value property of a MenuItem object. This value is shared with all menu items to which the MenuItemBinding object is applied. The specified value is not displayed in a menu item and is used to store any additional data about a menu item to which the MenuItemBinding object is applied, such as data used for handling postback events.
Note |
|---|
| You can override the value for an individual menu item by setting its Value property directly. |
Instead of using this property to specify the same value for each menu item, you can also bind the Value property of a MenuItem object to a field of a data source by setting the ValueField property. When rendered, the Value property of each menu item to which the MenuItemBinding object is applied contains the corresponding value from the field.
Note |
|---|
| If the Value and ValueField properties are both set, the ValueField property takes precedence. |
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.
The following code example demonstrates how to use the Value property to specify a nondisplayed value associated with a menu item. This value is used in each menu item to which the MenuItemBinding object is applied. For this example to work correctly, you must copy the sample XML data below to a file named Menu.xml.
The following code is sample site map data for the previous example.
