How to make Slideshow with fade in fade out effect in Expression Blend, WPF RRS feed

  • Question

  • Hi everybody.........

    I tried to create a slideshow with fadein/fade out effect in WPF.

    It is  working fine but when it repeats, means when 1st frame start rendering after last frame it shows a blank.


    I don’t know how to avoid this….


    My frames are XAML code, which I am loading at runtime.


    Code for animation………..

     Canvas[] canvasList;
       Storyboard myStoryboard;
        ParallelTimeline Ptime;
       DoubleAnimation[] da; 
    double interval1 = 5;
      myStoryboard = new Storyboard();
                    Ptime = new ParallelTimeline();
       da = new DoubleAnimation[4];
     for (int k = 0; k < 4; k++)
                        da[k] = new DoubleAnimation(1, 0, TimeSpan.FromSeconds(20));
                        da[k].AccelerationRatio = 0.5;
                        da[k].DecelerationRatio = 0.5;
                        da[k].BeginTime = TimeSpan.FromSeconds(interval1);
                        interval1 = interval1 + Properties.Settings.Default.AnimationSpeed;
     //canvasList Canvas Containers for each XAML File to be loaded.
                        Storyboard.SetTargetName(da[k], canvasList[k].Name);
                        Storyboard.SetTargetProperty(da[k], new PropertyPath(Canvas.OpacityProperty));
            public void LoadPlantAnimation()
                //Starting animation for loaded XAML files
                Ptime.RepeatBehavior = RepeatBehavior.Forever;

    I tryed in Expression Blend 1 also, but it is
    1) not showing intervals between frame change
    2) My no of frames is not fixed, so i don't knw how to deal with it in XAML

    looking for guidance ............
