MediaElement.CurrentStateChanged Event

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Occurs when the value of the CurrentState property changes.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)


Public Event CurrentStateChanged As RoutedEventHandler
public event RoutedEventHandler CurrentStateChanged
<MediaElement CurrentStateChanged="eventhandler"/>


It is possible for the CurrentStateChanged event to be raised multiple times before its event handlers are executed.

Although this event occurs when the CurrentState becomes invalid, that does not necessarily mean that the CurrentState property has a new value. For example, the CurrentState property might have switched from Playing to Buffering and back to Playing so rapidly that only a single CurrentStateChanged event was raised, in which case the property will not appear to have changed values. Also, your application should not assume an order in which the events occur, particularly for the transient states such as "Buffering". One of the transient states may have been skipped over in event reporting because it happened so rapidly.
