          OpenFileDialog openDlg =new OpenFileDialog();

           openDlg.InitialDirectory = @"c:\";

           openDlg.ShowDialog();

           MediaPathTextBox.Text = openDlg.FileName;

       }



      void PlayClick(object sender, EventArgs e)

       {

          if (MediaPathTextBox.Text.Length <= 0)

           {

               System.Windows.Forms.MessageBox.Show("Enter a valid media file");

              return;

           }

           VideoControl.Source = newUri(MediaPathTextBox.Text);

           VideoControl.Play();

       }
