为什么 Storyboard.SetTargetName 有效而 Storyboard.SetTarget 无效?这里 xaml -

    <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>

这里是 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();
}

最佳答案

我在这里找到了答案! Why don't these animations work when I'm using a storyboard?

Storyboard无法为 TranslateTransform 设置动画,因为它不是 UIElement。我现在就是这样做的! :)

  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)"));
