In this Article I am going to create a custom media player in wpf .First we are setting the background color and a static resource for button background image. Here i am using a VisualBrush to fill UI elements. The following code uses a VisualBrush to fill a rectangle.I am using media element as visual. A Visual object usually hosts one container panel such as a Grid or StackPanel and on this container.Add 5 buttons for play,forward,backward,stop and open file functionality.. We have to set LoadedBehavior="Manual" in media element.

Here is the xaml code:

Here is the C# code:

// code for play and pause

   public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
        // The Play method will begin the media if it is not currently active or
        // resume media if it is paused. This has no effect if the media is
        // already running.

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (this.button1.Content.ToString() == "Play")
            {
                this.videoelement.Play();
                this.button1.Content = "Pause";
            }
            else
            {
                this.videoelement.Pause();
                this.button1.Content = "Play";
            }
        }
        // code for stop
        private void StopButton_Click(object sender, RoutedEventArgs e)
        {
            // The Stop method stops and resets the media to be played from
            // the beginning.
            this.videoelement.Stop();
            this.button1.Content = "Play";

        }
        // code for forward

        private void ForwardButton_Click(object sender, RoutedEventArgs e)
        {
            this.videoelement.Position = this.videoelement.Position + TimeSpan.FromSeconds(10);
        }
        // code bvackward
        private void BackWard_Click(object sender, RoutedEventArgs e)
        {
            this.videoelement.Position = this.videoelement.Position - TimeSpan.FromSeconds(10);
        }
        // code for open file
        private void button2_Click(object sender, RoutedEventArgs e)
        {
            System.Windows.Forms.OpenFileDialog opnDialogue = new System.Windows.Forms.OpenFileDialog();
            opnDialogue.Filter = "Video Files(*.wmv)|*.wmv";
            if (opnDialogue.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                this.videoelement.Source = new Uri(opnDialogue.FileName);
            }
        }

    }
