    text
    copied!<p>There is Main frame on which there is a button and control and also stackpanel. Attempting to move worked animation from xaml to .cs I have wrote next cool function)):</p> <pre><code>private void ToggleButton_Checked(object sender, RoutedEventArgs e) { int heightBottom = 100; System.Windows.Thickness th = stackPanel1.Margin; th.Top = stackPanel1.Margin.Top + heightBottom; ThicknessAnimation animStackPanel1 = new ThicknessAnimation { From = stackPanel1.Margin, To = th, AccelerationRatio = 0.2, FillBehavior = FillBehavior.Stop, DecelerationRatio = 0.8, Duration = DURATION }; System.Windows.Thickness th2 = fxPSEditorView.Margin; th2.Right = fxPSEditorView.Margin.Right - heightBottom; th2.Bottom = fxPSEditorView.Margin.Bottom - heightBottom; ThicknessAnimation animPSEditorView = new ThicknessAnimation { From = fxPSEditorView.Margin, To = th2, AccelerationRatio = 0.2, FillBehavior = FillBehavior.Stop, DecelerationRatio = 0.8, Duration = DURATION }; Storyboard.SetTarget(animPSEditorView, fxPSEditorView); Storyboard.SetTargetProperty(fxPSEditorView, new PropertyPath(MarginProperty)); sb.Children.Add(animPSEditorView); Storyboard.SetTarget(animStackPanel1, stackPanel1); Storyboard.SetTargetProperty(stackPanel1, new PropertyPath(MarginProperty)); sb.Children.Add(animStackPanel1); sb.Begin();//null reference error here! }; </code></pre> <p>As I understand I must specify TWO parameters for sb.Begin - one for stackPanel1 and the other is for fxPSEditorView. But It does not takes a set of objects as first parameter. Any ideas how to run this animation will be wellcome ! Thank you</p>
