# How to: Control a MediaElement (Play, Pause, Stop, Volume, and Speed)
|
|
The following example shows how to control playback of media using a <xref:System.Windows.Controls.MediaElement>. The example creates a simple media player that allows you to play, pause, stop, and skip back and forth in the media as well as adjust the volume and speed ratio.
|
|
|
|
## Example
|
|
The code below creates the UI.
|
|
|
|
> [!NOTE]
|
|
> The <xref:System.Windows.Controls.MediaElement.LoadedBehavior%2A> property of <xref:System.Windows.Controls.MediaElement> must be set to `Manual` in order to be able to interactively stop, pause, and play the media.

|
|
|
|
## Example
|
|
The code below implements the functionality of the sample UI controls. The <xref:System.Windows.Controls.MediaElement.Play%2A>, <xref:System.Windows.Controls.MediaElement.Pause%2A>, and <xref:System.Windows.Controls.MediaElement.Stop%2A> methods are used to respectively play, pause and stop the media. Changing the <xref:System.Windows.Controls.MediaElement.Position%2A> property of the <xref:System.Windows.Controls.MediaElement> allows you to skip around in the media. Finally, the <xref:System.Windows.Controls.MediaElement.Volume%2A> and <xref:System.Windows.Controls.MediaElement.SpeedRatio%2A> properties are used to adjust the volume and playback speed of the media.
