How to: Control a MediaElement by Using a Storyboard
This example shows how to control a xref:System.Windows.Controls.MediaElement by using a xref:System.Windows.Media.MediaTimeline in a xref:System.Windows.Media.Animation.Storyboard.
Example
When you use a xref:System.Windows.Media.MediaTimeline in a xref:System.Windows.Media.Animation.Storyboard to control the timing of a xref:System.Windows.Controls.MediaElement, the functionality is identical to the functionality of other xref:System.Windows.Media.Animation.Timeline objects, such as animations. For example, a xref:System.Windows.Media.MediaTimeline uses xref:System.Windows.Media.Animation.Timeline properties like the xref:System.Windows.Media.Animation.Timeline.BeginTime%2A property to specify when to start a xref:System.Windows.Controls.MediaElement (start media playback). It also uses the xref:System.Windows.Media.Animation.Timeline.Duration%2A property to specify how long the xref:System.Windows.Controls.MediaElement is active (duration of media playback). For more information about using xref:System.Windows.Media.Animation.Timeline objects with a xref:System.Windows.Media.Animation.Storyboard, see Storyboards Overview.
This example shows how to create a simple media player that uses a xref:System.Windows.Media.MediaTimeline to control playback. The media player includes play, pause, resume, and stop buttons. The player also has a xref:System.Windows.Controls.Slider control that acts as a progress bar.
The following example creates the [!INCLUDETLA#tla_ui] for the media player.
