Remarks

Use the ToolTip property to specify the ToolTip text for the node. The ToolTip text is displayed when the mouse pointer is positioned over the node.

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 Globalization and Localization.
