MediaElement.Stop Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Stops and resets media to be played from the beginning.

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

Syntax

'Declaration
Public Sub Stop

public void Stop()

Remarks

This method will stop media playback if the media is playing. If the media is paused, the seek point is reset to the beginning of the media. This method has no effect if the media is already stopped.

Platform Notes

Silverlight for Windows Phone

If the video is in the paused state and Stop is called, the seek position will be reset, but the paused frame will continue to be rendered. This is a slightly different behavior than on Silverlight on the desktop. In Silverlight for desktop, if Stop is called while the video is in the paused state, the seek position will be reset and the paused frame will be replaced with black.

Examples

You can interactively control media playback by using the Play, Pause, and Stop methods of a MediaElement object. The following example defines a MediaElement object and several buttons for controlling media playback.

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>

    <MediaElement x:Name="media" Source="xbox.wmv" Width="300" Height="300" 
                  Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="3" />

    <!-- Stops media playback.-->
    <Button Click="StopMedia" 
     Grid.Column="0" Grid.Row="1" Content="Stop" />

    <!-- Pauses media playback. -->
    <Button Click="PauseMedia" 
     Grid.Column="1" Grid.Row="1" Content="Pause" />

    <!-- Begins media playback. -->
    <Button Click="PlayMedia" 
     Grid.Column="2" Grid.Row="1" Content="Play" />

</Grid>

The accompanying code creates several event handlers and uses the Stop, Pause, and Play methods to control the MediaElement.

Run this sample

Private Sub StopMedia(ByVal sender As Object, ByVal e As RoutedEventArgs)
    media.Stop()
End Sub

Private Sub PauseMedia(ByVal sender As Object, ByVal e As RoutedEventArgs)
    media.Pause()
End Sub

Private Sub PlayMedia(ByVal sender As Object, ByVal e As RoutedEventArgs)
    media.Play()
End Sub

private void StopMedia(object sender, RoutedEventArgs e)
{
    media.Stop();
}
private void PauseMedia(object sender, RoutedEventArgs e)
{
    media.Pause();
}
private void PlayMedia(object sender, RoutedEventArgs e)
{
    media.Play();
}
