Storyboard.SetTarget vs Storyboard.SetTargetName

Question

Why does the Storyboard.SetTargetName work, but the Storyboard.SetTarget is not? Here xaml is

<Grid Grid.Row="0" ClipToBounds="True"> <X:SmartContentControl x:Name="smartContent" Content="{Binding Path=MainContent}" ContentChanging="smartContent_ContentChanging"> <X:SmartContentControl.RenderTransform> <TranslateTransform x:Name="translateTransformNew" X="0" Y="0"/> </X:SmartContentControl.RenderTransform> </X:SmartContentControl> <ContentControl Content="{Binding ElementName=smartContent, Path=LastImage}"> <ContentControl.RenderTransform> <TranslateTransform x:Name="translateTransformLast" X="0" Y="0"/> </ContentControl.RenderTransform> </ContentControl> </Grid> 

Here c #

 private void smartContent_ContentChanging(object sender, RoutedEventArgs e) { Storyboard storyBoard = new Storyboard(); DoubleAnimation doubleAnimation1 = new DoubleAnimation(0.0, -smartContent.RenderSize.Width, new Duration(new TimeSpan(0, 0, 0, 0, 500))); DoubleAnimation doubleAnimation2 = new DoubleAnimation(smartContent.RenderSize.Width, 0.0, new Duration(new TimeSpan(0, 0, 0, 0, 500))); doubleAnimation1.AccelerationRatio = 0.5; doubleAnimation2.DecelerationRatio = 0.5; storyBoard.Children.Add(doubleAnimation1); storyBoard.Children.Add(doubleAnimation2); Storyboard.SetTarget(doubleAnimation1, this.translateTransformLast); //--- this does not work //Storyboard.SetTargetName(doubleAnimation1, "translateTransformLast"); -- this works Storyboard.SetTargetProperty(doubleAnimation1, new PropertyPath(TranslateTransform.XProperty)); Storyboard.SetTarget(doubleAnimation2, this.translateTransformNew);//--- this does not work //Storyboard.SetTargetName(doubleAnimation2, "translateTransformNew"); -- this works Storyboard.SetTargetProperty(doubleAnimation2, new PropertyPath(TranslateTransform.XProperty)); if (smartContent.LastImage != null) storyBoard.Begin(); }

I found the answer here! Why don't these animations work when I use the storyboard?

The storyboard can not animate TranslateTransform, as it is not a UIElement. Here is how I do it now! :)

  Storyboard.SetTarget(doubleAnimation1, this.lastImage); Storyboard.SetTargetProperty(doubleAnimation1, new PropertyPath("RenderTransform.(TranslateTransform.X)")); Storyboard.SetTarget(doubleAnimation2, this.smartContent); Storyboard.SetTargetProperty(doubleAnimation2, new PropertyPath("RenderTransform.(TranslateTransform.X)"));
