Occurs when a timeline marker is encountered during media playback.
(in System.Windows.dll)
Visual Basic (Declaration)
Public Event MarkerReached As TimelineMarkerRoutedEventHandler
Dim instance As MediaElement
Dim handler As TimelineMarkerRoutedEventHandler
AddHandler instance.MarkerReached, handler
public event TimelineMarkerRoutedEventHandler MarkerReached
<MediaElement MarkerReached="eventhandler"/>
The MarkerReached event is not raised when the MediaElement seeks past a timeline marker. This event is raised whenever a marker associated with the media is reached. The marker might come from one of three locations:
Stored in the metadata of the currently opened media.
Associated with the currently opened media and coming from a separate stream.
Explicitly added to the Markers collection for the currently opened media, using script.
The following example creates a MediaElement object and responds to its MarkerReached event. Each time a timeline marker is reached, the example displays the timeline marker's Time, Type, and Text values.
<Grid>
<StackPanel>
<TextBlock x:Name="timeTextBlock" FontSize="12">Time:</TextBlock>
<TextBlock x:Name="typeTextBlock" FontSize="12">Type:</TextBlock>
<TextBlock x:Name="valueTextBlock" FontSize="12">Value:</TextBlock>
<Canvas>
<MediaElement x:Name="media" Width="300" Height="200"
MarkerReached="OnMarkerReached" Source="thebutterflyandthebear.wmv"/>
</Canvas>
</StackPanel>
</Grid>
public void OnMarkerReached(object sender, TimelineMarkerRoutedEventArgs e)
{
timeTextBlock.Text = e.Marker.Time.Seconds.ToString();
typeTextBlock.Text = e.Marker.Type.ToString();
valueTextBlock.Text = e.Marker.Text;
}
