  Hi there,
  
  I created a MediaPlayer using MediaElement, but I´ve a problems creating seek bar. I can´t sincronize my seek bar with player.
  
  Here is my code:
  
   public ReunioesAudio()
          {
              InitializeComponent();
              MediaEl.Loaded += new RoutedEventHandler(MediaEl_Loaded);
              MediaEl.CurrentStateChanged += new RoutedEventHandler(MediaEl_CurrentStateChanged);
              timer = new DispatcherTimer();
              timer.Interval = TimeSpan.FromMilliseconds(50);//500
              timer.Tick+=new EventHandler(timer_Tick);
          }
  
   void MediaEl_CurrentStateChanged(object sender, RoutedEventArgs e)
          {
              if (MediaEl.CurrentState == MediaElementState.Playing)
              {
                  timer.Start();
                  Slider1.Maximum = MediaEl.NaturalDuration.TimeSpan.TotalMinutes;
              }
              else
              {
                  timer.Stop();
              }
          }
  
   private void timer_Tick(object sender, EventArgs e)
          {
              if (MediaEl.NaturalDuration.TimeSpan.TotalSeconds > 0 && !VideoBloqueado)
              {
                  txtVideoPosition.Text = MediaEl.Position.Minutes + ":" + MediaEl.Position.Seconds;
                 this.Slider1.Value = this.MediaEl.Position.TotalSeconds / MediaEl.NaturalDuration.TimeSpan.TotalSeconds;
                 
  
                
              }
          }
  
          double percent;
  
          private void Slider1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
          {
              VideoBloqueado = true;
          }
  
          private void Slider1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
          {
              VideoBloqueado = false;
             
              MediaEl.Position = TimeSpan.FromSeconds(Slider1.Value);
  
           
          }
  
   private void MediaEl_MediaOpened(object sender, RoutedEventArgs e)
          {
              if (MediaEl.NaturalDuration.HasTimeSpan)
              {
                  TimeSpan ts = MediaEl.NaturalDuration.TimeSpan;
                  
                  
                  //Slider1.LargeChange = Math.Min(10, ts.Seconds / 10);
              }
              //MediaEl.Play();
          }
  
  My seek bar doesn´t work and i don´t know why.
  
  Any help please..
  
  Thanks in advance,

  Hi Manuel,
  
  From your code snippets it seems you're not using the RadMediaPlayer control but you're rather trying to create a custom media player control.
  
  This is why I wanted to ask you if you can use the RadMediaPlyer control in this scenario - the control has a built-in timeline that shows the length of the played media and indicates the progress of the video. This is why if you use the RadMediaPlayer control you won't have to create a RadSlider control to display the current progress of the media, neither a TextBlock displaying the elapsed time.
