Hi,
I'm doing a Surface Application.
And there I have something like a bulletin board where little cards with news on it are pinned on.
On click they shall fly out of the board and scale bigger.
My storyboard works well, except for the first time it runs. It's not a smooth animation then but it scales to its final size immediately and it's the same with the orientation-property. Just the center-property seems to behave correctly.
This is an example for one of my Storyboards doing that:
Storyboard stb = new Storyboard();
PointAnimation moveCenter = new PointAnimation();
DoubleAnimationUsingKeyFrames changeWidth = new DoubleAnimationUsingKeyFrames();
DoubleAnimationUsingKeyFrames changeHeight = new DoubleAnimationUsingKeyFrames();
DoubleAnimationUsingKeyFrames changeOrientation = new DoubleAnimationUsingKeyFrames();
moveCenter.From = News1.ActualCenter;
moveCenter.To = new Point(250, 400);
moveCenter.Duration = new Duration(TimeSpan.FromSeconds(1.0));
moveCenter.FillBehavior = FillBehavior.Stop;
stb.Children.Add(moveCenter);
Storyboard.SetTarget(moveCenter, News1);
Storyboard.SetTargetProperty(moveCenter, new PropertyPath(ScatterViewItem.CenterProperty));
changeWidth.Duration = TimeSpan.FromSeconds(1);
changeWidth.KeyFrames.Add(new EasingDoubleKeyFrame(266, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1))));
changeWidth.FillBehavior = FillBehavior.Stop;
stb.Children.Add(changeWidth);
Storyboard.SetTarget(changeWidth, News1);
Storyboard.SetTargetProperty(changeWidth, new PropertyPath(FrameworkElement.WidthProperty));
changeHeight.Duration = TimeSpan.FromSeconds(1);
changeHeight.KeyFrames.Add(new EasingDoubleKeyFrame(400, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1))));
changeHeight.FillBehavior = FillBehavior.Stop;
stb.Children.Add(changeHeight);
Storyboard.SetTarget(changeHeight, News1);
Storyboard.SetTargetProperty(changeHeight, new PropertyPath(FrameworkElement.HeightProperty));
changeOrientation.Duration = TimeSpan.FromSeconds(1);
changeOrientation.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1))));
changeOrientation.FillBehavior = FillBehavior.Stop;
stb.Children.Add(changeOrientation);
Storyboard.SetTarget(changeOrientation, News1);
Storyboard.SetTargetProperty(changeOrientation, new PropertyPath(ScatterViewItem.OrientationProperty));
stb.Begin(this);
News1.Center = new Point(250, 400);
News1.Orientation = 0;
News1.Width = 266;
News1.Height = 400;
Pin1.Visibility = Visibility.Collapsed;
news1IsOutside = true;
Scroll1.IsEnabled = true;
What's wrong with it?
