C# 将按钮从一点设置为另一点的动画
我有一个扩展器，包含一些元素和一个按钮。当扩展器折叠时，我想在扩展器的标题中显示按钮，以便于访问。当扩展器展开时，我希望按钮成为扩展器内容的一部分 当扩展器展开和折叠时，我可以让标题中的按钮淡入淡出，但我想更进一步。我希望在收拢时，扩展器内容中的按钮向上移动到标题中的位置，在展开时向下移动到内容的位置 通过使用“混合”，在两个按钮之间画一条线，并将其转换为运动路径，我可以稍微接近。然而，使用这种方法很难获得精确的定位。我的一部分感觉，画出这条路有点过于复杂了。我只想让按钮A变成按钮B 目前我只关心按钮的位置。这两个按钮大小不同，但设置按钮宽度和高度的动画更直接：） 这是我快速制作的一个示例程序，用于演示我正在使用的内容。它主要只是提供一个视觉布局。本例中不包括淡入淡出动画和路径动画C# 将按钮从一点设置为另一点的动画,c#,wpf,blend,wpf-animation,C#,Wpf,Blend,Wpf Animation,我有一个扩展器，包含一些元素和一个按钮。当扩展器折叠时，我想在扩展器的标题中显示按钮，以便于访问。当扩展器展开时，我希望按钮成为扩展器内容的一部分 当扩展器展开和折叠时，我可以让标题中的按钮淡入淡出，但我想更进一步。我希望在收拢时，扩展器内容中的按钮向上移动到标题中的位置，在展开时向下移动到内容的位置 通过使用“混合”，在两个按钮之间画一条线，并将其转换为运动路径，我可以稍微接近。然而，使用这种方法很难获得精确的定位。我的一部分感觉，画出这条路有点过于复杂了。我只想让按钮A变成按钮B 目前我只关

谢谢这不是一件小事 基本上，您试图在视觉树的两个完全不同的部分之间设置一个按钮的动画，因此您必须对整个内容进行模板化，并将所有内容包装在一个父布局中，该布局包含您的扩展器和您尝试设置动画的按钮 模板化您的扩展器应该不会太困难，只需将光标移动到它的XAML，转到properties选项卡，选择“Template”，然后单击右侧的小正方形，为新的ControlTemplate生成所有代码。我已经在下面的代码中为您完成了这项工作，但是主题可能完全错误，因此您需要自己完成 下一步是创建两个矩形，一个在expanders标题中，另一个在其内容区域中。将这些按钮的大小设置为您想要的大小，但将填充设置为透明；它们只是帮助布局的占位符，稍后您将使用它们来对齐按钮控件 现在，您需要返回到ControlTemplate并将所有内容（即顶级边框）包装到网格中。您还需要将实际按钮作为此网格的子级放置 最后，您将需要一个绑定到您创建的两个矩形（以便它可以计算起点和终点）、父栅格（以便它有一个父控件可以相对设置按钮动画）和扩展器（以便它可以触发动画以响应扩展器的展开和折叠）的行为。然后，实际动画本身可以是一个厚度动画，该动画为按钮的边距设置动画 把所有这些放在一起，你会得到：
