Occurs when an item selection (highlighting) is moved to another item within the editor's dropdown.
public event SelectionChangedEventHandler PopupContentSelectionChanged
Public Event PopupContentSelectionChanged As SelectionChangedEventHandler
The PopupContentSelectionChanged event's data class is SelectionChangedEventArgs. The following properties provide information specific to this event:
|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:
|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.|
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.
