How to: Get the Non-Animated Value of an Animated Property

To get the non-animated value of an object's animated property, you use the object's GetAnimationBaseValue method. UIElement, Animatable, and ContentElement each have their own implementation.

In the following example, the non-animated values of animated properties are retrieved and displayed.


   This sample shows how to use the 
   Animatable.GetAnimationBaseValue and 
   UIElement.GetAnimationBaseValue methods
   to get the non-animated value of an
   animated Animatable or UIElement.

        public GetAnimationBaseValueExample()

            WindowTitle = "GetAnimationBaseValue Example";
            StackPanel myPanel = new StackPanel();
            myPanel.Margin = new Thickness(20.0);    

            // Create a button.
            Button animatedButton = new Button();
            animatedButton.Content = "Click Me";
            animatedButton.Width = 100;
            animatedButton.Margin = new Thickness(100);

            // Create and animate a RotateTransform and 
            // apply it to the button's RenderTransform 
            // property.
            animatedRotateTransform = new RotateTransform();

            animatedButton.RenderTransformOrigin = new Point(0.5,0.5);
            // Animate the button's width.
            DoubleAnimation widthAnimation = 
                new DoubleAnimation(120, 300, TimeSpan.FromSeconds(5));

            animatedButton.BeginAnimation(Button.WidthProperty, widthAnimation);

            // Handle button clicks.
            animatedButton.Click += new RoutedEventHandler(animatedButton_Clicked);           

            // Add the button to the panel.
            this.Content = myPanel;

        // Display the base value for Button.Width and RotateTransform.Angle. 
        private void animatedButton_Clicked(object sender, RoutedEventArgs e)
            Button animatedButton = (Button)sender;
