Property Value



true if the ToolTip is visible; otherwise, false. The default is false.


This property is not typically set in XAML.

A ToolTip must be assigned to another UI element that is its owner. In XAML, use the ToolTipService.Tooltip attached property to assign the ToolTip to an owner. In code, use the ToolTipService.SetToolTip method to assign the ToolTip to an owner. If you set the IsOpen property to true in your app code before the ToolTip is assigned to an owner, an exception is thrown.
