使用ToggleButton和StackPanel+Border实现圆角开关按钮动画效果

<ToggleButton  Height="40"  Width="105" HorizontalAlignment="Left" Margin="138,122,0,0" Name="button1" VerticalAlignment="Top" Click="button1_Click">

            <ToggleButton.Content>

                <StackPanel Name="s1" Width="100" Height="22" Orientation="Horizontal" HorizontalAlignment="Left">

                    <Border Name="cd1" CornerRadius="10" BorderThickness="1" Width="100" BorderBrush="#FF001900">

                        <Border.Background>

                            <ImageBrush ImageSource="/MoveButton;component/Images/12.png" />

                        </Border.Background>

                    </Border>

                    <Border Name="cd2" CornerRadius="10" BorderThickness="1" Width="100" BorderBrush="#FF001900">

                        <Border.Background>

                            <ImageBrush ImageSource="/MoveButton;component/Images/13.png" />

                        </Border.Background>

                    </Border>

                </StackPanel>

            </ToggleButton.Content>

        </ToggleButton>

        private void button1_Click(object sender, RoutedEventArgs e)

        {

            if (button1.IsChecked == true)

            {

                DoubleAnimation d1 = new DoubleAnimation();

                d1.From = 0;

                d1.To = 100;

                d1.Duration = new Duration(TimeSpan.Parse("0:0:0.2"));

                cd2.BeginAnimation(StackPanel.WidthProperty, d1);



                DoubleAnimation d2 = new DoubleAnimation();

                d2.From = 100;

                d2.To = 0;

                d2.Duration = new Duration(TimeSpan.Parse("0:0:0.2"));

                cd1.BeginAnimation(StackPanel.WidthProperty, d2);

            }



            if (button1.IsChecked == false)

            {

                DoubleAnimation d1 = new DoubleAnimation();

                d1.From = 100;

                d1.To = 0;

                d1.Duration = new Duration(TimeSpan.Parse("0:0:0.2"));

                cd2.BeginAnimation(StackPanel.WidthProperty, d1);



                DoubleAnimation d2 = new DoubleAnimation();

                d2.From = 0;

                d2.To = 100;

                d2.Duration = new Duration(TimeSpan.Parse("0:0:0.2"));

                cd1.BeginAnimation(StackPanel.WidthProperty, d2);

            }

        }

代码没精简，无图无真相，看看OFF和ON
