首先：我只是想开始使用WPF并稍微使用它，所以事情可能不是完全最优的，我对任何建议的改进感到高兴。
我正在为我的按钮设置以下样式和模板，并尝试在鼠标悬停时将它们放大，而对于点击则更小，这几乎可以正常工作：
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="{x:Null}" />
<Setter Property="Width" Value="80" />
<Setter Property="Height" Value="80" />
<Setter Property="Margin" Value="10" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Name="ButtonGrid" Width="{TemplateBinding Width}"

问题是，当我单击一个按钮时，MouseOver Trigger不再执行或者缩放不起作用。因此按钮不再在MouseOver上放大。
非常感谢提示：）

将IsMouseOver触发器更改为MultiTrigger并将IsPressed触发器移动到IsMouseOver多触发器上方，如下所示。
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
