Remarks

When the Menu control is bound to a data source, use the ToolTipField property to specify the name of the field to bind to the ToolTip property of a MenuItem object. When rendered, the ToolTip property of each menu item to which the MenuItemBinding object is applied contains the corresponding value from the field. The specified text is displayed when the user positions the mouse pointer over a menu item.

Note

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

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

Note

If the ToolTip and ToolTipField properties are both set, the ToolTipField property takes precedence.
