MediaElement::Stop Method

Stops and resets media to be played from the beginning.

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

public:
void Stop()
You cannot use methods in XAML.

ExceptionCondition
InvalidOperationException

The Clock property is not nullptr.

This method can be used only when the Clock property is nullptr. When the Clock property is non-nullptr, the timing engine controls media playback behavior.

This method has an effect only if the LoadedBehavior property is set to Manual.

The following example shows how to control playback of media using a 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.

The code below creates the UI.

NoteNote:

The LoadedBehavior property of MediaElement must be set to Manual in order to be able to interactively stop, pause, and play the media.

The code below implements the functionality of the sample UI controls. The Play, Pause, and Stop methods are used to respectively play, pause and stop the media. Changing the Position property of the MediaElement allows you to skip around in the media. Finally, the Volume and SpeedRatio properties are used to adjust the volume and playback speed of the media.
