WPF中如何用Storyboard

XML code

<Storyboard x:Key="Storyboard1"><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)" Storyboard.TargetName="grid"><EasingDoubleKeyFrame KeyTime="0" Value="1"/><EasingDoubleKeyFrame KeyTime="0:0:1" Value="-1"/><EasingDoubleKeyFrame KeyTime="0:0:2" Value="-1"/></DoubleAnimationUsingKeyFrames></Storyboard>

上面是在Blend中做好的一段翻转动画代码，想在后台动态定义，该如何写呢？
似乎和SL不太一样，在SL里的方式，拿到WPF中就会报错

C# code

Storyboard keyFrameboard = new Storyboard();            DoubleAnimationUsingKeyFrames dakeyframe = new DoubleAnimationUsingKeyFrames();            Storyboard.SetTarget(dakeyframe, icCurrent);            Storyboard.SetTargetProperty(dakeyframe, new PropertyPath("(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)"));            dakeyframe.BeginTime = new TimeSpan(0, 0, 0);            EasingDoubleKeyFrame edKeyFrame = new EasingDoubleKeyFrame();            edKeyFrame.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(1));            edKeyFrame.Value = -1;            dakeyframe.KeyFrames.Add(edKeyFrame);            keyFrameboard.Children.Add(dakeyframe);            keyFrameboard.Begin();

上面是我的写法，但报如下错误：

Cannot resolve all property references in the property path '(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)'. Verify that applicable objects support the properties.

请高手指教！！！

看了你的代码，还是因为没有定义

要让自定义控件进行旋转变换，需要对自定义控件的转换进行定义，你在自定义控件里面定义的转变，在mainwindow中找不到的

正确方法如下，有两种：

一、xaml方式

HTML code

     <Canvas x:Name="canvasBottom" Width="500" Height="500" Background="Gray" Grid.Row="1">      <my:ImageContainer x:Name="ic" Width="200" Height="200" >        <my:ImageContainer.RenderTransform>          <TransformGroup>            <ScaleTransform/>            <SkewTransform/>            <RotateTransform/>            <TranslateTransform/>          </TransformGroup>        </my:ImageContainer.RenderTransform>      </my:ImageContainer>    </Canvas>
