The ToolTipEventArgs type exposes the following members.

Properties
  NameDescription
Public property HandledGets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. (Inherited from RoutedEventArgs.)
Public property OriginalSourceGets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs.)
Public property RoutedEventGets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs.)
Public property SourceGets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)

Remarks

When a tooltip opens and closes, this class provides event information. The element that specifies the tooltip inherits from either FrameworkElement or ContentElement. Therefore, open and close events exist on both of these classes. The following table lists the events that use this class.

These events are registered by the ToolTipService class as the ToolTipOpeningEvent and ToolTipClosingEvent fields. The FrameworkElement and FrameworkContentElement classes both implement the ToolTipService and expose this event by defining the events in the previous table

The ToolTipEventArgs class overrides the InvokeEventHandler method. However, this protected member does not appear on the ToolTipEventArgs list of members because the method is sealed and cannot be overridden in classes from ToolTipEventArgs. The implementation of the method in this class casts the event handler delegate that is provided as a parameter to the method to the ToolTipEventHandler type.

If the tooltip is defined as a ToolTip object, the Opened and Closed events of the ToolTip class are also raised when a tooltip opens and closes.
