Hi,

I am working on media player . I have to keep seekbar for the player. I am using slider . Task is the slider should move with media .But problem is that it is just stuck there and not moving. My code goes here

xaml

HTML

<MediaElement Height="Auto" HorizontalAlignment="Stretch" Margin="-12,-45,0,0" Name="mediaElement1"  CurrentStateChanged="mediaElement1_CurrentStateChanged"
 VerticalAlignment="Stretch" Width="Auto" AutoPlay="True" Loaded="mediaElement1_Loaded" MediaEnded="mediaElement1_MediaEnded" MediaOpened="mediaElement1_MediaOpened" />
            <Slider Name="timelineSlider" Margin="5,348,5,5" ValueChanged="timelineSlider_ValueChanged" />

xaml.cs

HTML

private void mediaElement1_MediaOpened(object sender, RoutedEventArgs e)
        {
            timelineSlider.Maximum = mediaElement1.NaturalDuration.TimeSpan.TotalMilliseconds;
        }

        private void timelineSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
        {
            int SliderValue = (int)timelineSlider.Value;
            TimeSpan ts = new TimeSpan(0, 0, 0, 0, SliderValue);
            mediaElement1.Position = ts;
        }

Hi , first of all i would suggest to add such propertsion to MediaElement declaration

And the question is formed what kind of media did you play ??
Is it a buffered ? or it is just from file ?
According to answer , default media behaviors could be applied

Ok , if it not buffered try to do the next:

XML

<slider x:name="timelineSlider" thumb.dragstarted="seekBar_DragStarted" thumb.dragcompleted="seekBar_DragCompleted">

C#

private void mediaElement1_MediaOpened(object sender, RoutedEventArgs e)
 {
    TimeSpan ts = mediaElement1.NaturalDuration.TimeSpan;
    timelineSlider.Maximum = ts.TotalSeconds;
    timelineSlider.SmallChange = 1;
    timelineSlider.LargeChange = Math.Min(10, ts.Seconds / 10);
 }

C#

private void seekBar_DragCompleted(object sender, DragCompletedEventArgs e)
{
    mediaElement1.Position = TimeSpan.FromSeconds(timelineSlider.Value);
}
