我们正在为 XBAP 应用程序创建自定义 WPF 控件(不是用户控件)，并且我们希望添加 Storyboard动画，以便当鼠标悬停在控件上时将控件缩放为其原始大小的 110%。我们使用 Blend 来创建 Storyboard ，它编译得很好……但是，当我们运行时，它的动画速度并没有达到 110%。我已经阅读过一些文章，指出不能在 XAML 中为自定义控件制作 Storyboard动画。有谁知道如何完全在 XAML 中对自定义控件执行此操作？
这是我们的自定义控件的 XAML:

最佳答案
有可能......我只是认为你需要移动一些东西。 特别是，您需要将 Storyboard 移至 ControlTemplate.Resources 部分...并将触发器移至 ControlTemplate.Triggers 部分。
我实际上构建了一个快速示例来尝试一下......并且它有效。这是:
