MediaElement.MarkerReached Event
Occurs when a timeline marker is encountered during media playback.
Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)
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>

I used the MediaElement control in my project, and write code like the sample the same, but the MarkerReached event isn't raised, of couse I added the marker instnace. Anybody can tell me the reason? Thanks!
