Public Event ItemsSourceChanged As ItemsSourceChangedEventHandler
The ItemsSourceChanged event's data class is ItemsSourceChangedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| 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. |
| NewValue | Gets a new ItemsSource property value. |
| OldValue | Gets an old ItemsSource property value. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs. |
| 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) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs. |
| 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. |
The ItemsSourceChanged event is fired after an editor’s ItemsSource property value has been changed. Use the OldValue property to get the previous ItemsSource property value. The NewValue property returns the new ItemsSource property value.
