Identifier field


Metadata properties set to true



Occurs when StaysOpen is set to false when a tooltip is not open.

A value of false for the StaysOpen property is not supported for a ToolTip when it is not open. To create a tooltip that stays open until the mouse button is pressed when it is outside the tooltip, you must set both the StaysOpen property and the IsOpen property to true. If StaysOpen is set to false when the tooltip is not open, a NotSupportedException occurs.
