MenuItemBinding.ToolTip Property

Gets or sets the ToolTip text for a menu item to which the MenuItemBinding object is applied.

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

public string ToolTip { get; set; }

Property Value

Type: System.String
The ToolTip text for a menu item 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 ToolTip property to specify the text to bind to the MenuItem.ToolTip property of a MenuItem object. This ToolTip is shared with all menu items to which the MenuItemBinding object is applied. When the user positions the mouse pointer over a menu item, the specified text is displayed.

NoteNote

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

Instead of using this property to specify the same ToolTip for each menu item, you can also bind the ToolTip property of a MenuItem object to a field of a data source by setting the ToolTipField property. When rendered, the ToolTip property of each menu item to which the MenuItemBinding object is applied contains the corresponding value from the field.

NoteNote

If the ToolTip and ToolTipField properties are both set, the ToolTipField 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 ToolTip property to specify the ToolTip to display when the user positions the mouse pointer over a menu item. This ToolTip is displayed for 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.
