Tool-tips are short text messages displayed when the mouse pointer hovers over an object for a while. To enable tool-tips, set the ShowToolTips property to true. The delay before a tool-tip appears is set via the ToolTipDelay property.

Use the ToolTip property of items to specify what text should be displayed as a tool-tip. Each cell of a table can have a distinct tool-tip, which can be set through the CellToolTip indexed property. To change the style of the tool-tips use ToolTipStyle property. Use standard EOL line dividers to get multi-lined tool-tips.

Tool-tip's text is also used as a value of the ALT attribute of image map areas corresponding to items; see HtmlBuilder for more information.
