Question

我有4个带有动画的故事板。我想要的是防止故事板在加载窗口时自动播放。我希望它们只在窗口内单击鼠标时播放。我在一个故事板上尝试了以下内容：

private void UserControl_Loaded(object sender, RoutedEventArgs e)
    {

        this.target2animation_BeginStoryboard.Storyboard.Stop();

    }

private void UserControl_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            this.target2animation_BeginStoryboard.Storyboard.Begin();
        }

它不起作用。它在窗口加载时播放一次。我甚至尝试过Freeze，Pause而不是Stop。仍然没有奏效。

然而，如果我点击，故事板总是从头开始，所以鼠标点击事件正在发挥作用。

请帮忙！

这是target2animate storyboard的代码（通过表达式混合创建）

<Storyboard x:Key="target2animation" RepeatBehavior="0:0:10">
        <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.X)" Storyboard.TargetName="ellipse">
            <EasingDoubleKeyFrame KeyTime="0:0:0.8" Value="35">

                </EasingDoubleKeyFrame.EasingFunction>
            </EasingDoubleKeyFrame>
        </DoubleAnimationUsingKeyFrames>
    </Storyboard>

如何在窗口加载时防止故事板自动播放？我无法做到
