I'm using Media Element to Dispaly Video & pictures the binding to Source Property made with Convertor that Save the Binary Data to A file and return the URI of this file to the Media Element Every thing works well but When Edit The File and put other Movie or Picture the Displayed Picture Is Still the previous one until I close the Window and ReOpen it to get the Newest one this is the Binding Xaml :

<MediaElement.Source >
<MultiBinding Mode="TwoWay" Converter="{StaticResource RefConverter}" >
<Binding Path="AddAnimationReference.File" Mode="TwoWay" />
<Binding Path="AddAnimationReference.Extention" Mode="TwoWay" />
<Binding Path="AddAnimationId" Mode="OneWay" />
</MultiBinding>
</MediaElement.Source>

The convertor Code is so simple and I debugged it so I think there is no problem on this . thanks :)

this is the last thing I Achieved : I added the animation to the buttons programmatically this is the code behind file :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Media.Animation;

namespace practiceOnAnimationClasses
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}

    DoubleAnimationUsingPath Animation1 = new DoubleAnimationUsingPath();

    private void Window\_Loaded(object sender, RoutedEventArgs e)
    {
        List<Button> buttons = new List<Button>(5);
        buttons.Add(new Button() { Width = 120d, Height = 75d, Content = "Advertisement 1" });
        buttons.Add(new Button() { Width = 120d, Height = 75d, Content = "Advertisement 2" });
        buttons.Add(new Button() { Width = 120d, Height = 75d, Content = "Advertisement 3" });
        buttons.Add(new Button() { Width = 120d, Height = 75d, Content = "Advertisement 4" });
        buttons.Add(new Button() { Width = 120d, Height = 75d, Content = "Advertisement 5" });

        // Storyboard AnimationRectanglePath = (Storyboard)this.Resources\["StoryboardPath"\];

        int count = 0;
        foreach (var item in buttons)
        {
            MainCanvas.Children.Add(item);
            DoubleAnimation myDoubleAnimation = new DoubleAnimation();
            myDoubleAnimation.From = 75 + (count \* item.Width);
            myDoubleAnimation.To = 800;
            myDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(15));
            myDoubleAnimation.AutoReverse = false;
            myDoubleAnimation.RepeatBehavior = RepeatBehavior.Forever;

            // Apply the animation to the button's Width property.
            item.BeginAnimation(Canvas.LeftProperty, myDoubleAnimation);
            count++;
        }
    }
}

}

Xaml File it only contains the mainCanvas that I will Add Buttons to It the movement is very creasy and wrong How Can I make the movement
