我试图在鼠标悬停期间更改网格内部路径的颜色。为此，我使用Visual状态管理器和故事板。 下面是我的网格
<Grid Name="PART_icondisp" Grid.Column="2" Grid.Row="1">

以下是我的故事板
<VisualState x:Name="Hover">

<DoubleAnimation Storyboard.TargetName="PART_Pressed" Storyboard.TargetProperty="Opacity" Duration="0" To="0.0" />
</Storyboard>
</VisualState>
当我尝试将鼠标悬停在该按钮上时，它会显示System.InvalidOperationException，并且在'System.Windows.Controls.Grid'的名称范围内找不到'PART_icondisp'名称。
请帮我解决这个问题。

您正尝试更改动画中的Path.Fill属性，但Storyboard.TargetName设置为PART_icondisp。但是，该元素是Grid，因此您似乎感到困惑。另外，我不会使用VisualStateManager来执行简单的鼠标移动动画，而是更喜欢使用简单的DataTrigger：
