C# 网格内路径的WPF填充颜色

您正在尝试更改动画中的Path.Fill属性，但Storyboard.TargetName已设置为PART_icondisp。但是，该元素是一个网格，因此您似乎感到困惑。此外，我不会使用VisualStateManager执行简单的鼠标悬停动画，而是更喜欢使用简单的DataTrigger： 试试这个：

即使我将该名称更改为“IconSave”，也会出现同样的错误。在“System.Windows.Controls.Grid”的名称范围中找不到名称。您需要在IconSave可见的节点上指定该名称。您能提供一些示例让我更好地理解吗？将您的故事板添加到Grid.Resources或Path.ResourcesHanks以获取代码段，是的，数据触发器很简单。但我尝试使用VSM。然后显示所有相关代码，例如整个VisualStateManager及其父级。否则我们无法知道您的问题是什么。我正在使用Devexpress控件。我更新了问题。我想它无法找到该网格。如何公开网格部分图标很难找到网格部分图标
