Event Data

The PopupContentSelectionChanged event's data class is SelectionChangedEventArgs. The following properties provide information specific to this event:

Property Description
AddedItems Gets a list that contains the items that were selected.
Handled Gets 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.
OriginalSource Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RemovedItems Gets a list that contains the items that were unselected.
RoutedEvent Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Source Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

The event data class exposes the following methods:

Method Description
InvokeEventHandler(Delegate, Object) Performs the proper type casting to call the type-safe SelectionChangedEventHandler delegate for the SelectionChanged event.
OnSetSource(Object) When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

For a checked combo box, the PopupContentSelectionChanged event is fired each time an item, displayed within the editor's dropdown, has been checked or unchecked. For a native combo box or lookup editor, this event is fired when an item highlighting is moved to another item.
