如何更改BorderBrush上的CheckBox Background和MouseOver颜色？我试过这种方式，但它不起作用：
<CheckBox Style="{DynamicResource checkBox}">CheckBoxText</CheckBox>
这是我的风格：
<Style TargetType="{x:Type CheckBox}" x:Key="checkBox">
<!-- This part changes the colors -->
<Setter Property="BorderBrush" Value="LightGray" />
<Setter Property="BorderThickness" Value="3" />
<Setter Property="Background" Value="LightGray" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<!-- This part is not changing the colors -->
<Setter Property="BorderThickness" Value="3" />
<Setter Property="Background" Value="Gray" />
<Setter Property="BorderBrush" Value="Gray" />
</Trigger>
</Style.Triggers>
</Style>
更改这些颜色适用于<Trigger Property="IsChecked" Value="True">条件。但它不适用于IsMouseOver。

您只是错过了TargetName来告诉它您应用setter更改的对象。所以例如，只需要你的;
<Setter Property="Background" Value="Gray" />
并制作它;
<Setter TargetName="ObjectNameToChangeStuff" Property="Background" Value="Gray" />
假设objectname可能是边框或其他东西，那么它就像
<Border x:Name="ObjectNameToChangeStuff"/>
希望这会有所帮助，欢呼。
PS - 因为我刚才注意到了。您希望ControlTemplate中的这些触发器不是您的样式，因此ControlTemplate.Triggers而不是Style.Triggers（因为您与ControlTemplate的元素交互）与{{3}比较，这样你就可以更容易地发现你的差异。 ：）
增加：
因此，如果您的模板设置类似于此（伪）;
<Style x:Key="{x:Type CheckBox}" TargetType="CheckBox">
<!-- Blah blah setter stuff for defaults -->
<Setter Property="Background" Value="DefaultColorForThisThing"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="CheckBox">
<BlahBlah Stuff/>...
<!-- Whatever CLR object that supports it, for example -->
<Border Background="{TemplateBinding Background}"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
...然后你应该能够在依赖属性中传递一个值，通过样式触发器与控件模板内的对象进行通信。

如果有人仍在尝试找出答案，则可以像这样设置样式并覆盖控件模板：
<Style x:Key="checkboxTemplate" TargetType="{x:Type CheckBox}">
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="FocusVisualStyle" Value="{DynamicResource CheckBoxFocusVisual}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">

Pressed和MouseOver上的边界=浅蓝Pressed和MouseOver上的背景=黄色我对此example template进行了略微修改，以解决悬停在边框颜色上的问题。
PS：这是一种非常幼稚的方法，肯定有一种方法可以将其压缩下来，我也是wpf初学者：P

我尝试覆盖OnMouseOver事件，但没有成功。我同意Yoghurt的观点，即制作模板是最佳解决方案。但是，我建议您使用Unicode字符，而不是使用路径绘制对勾标记。有关不同的unicode字符，请参见Wikipedia。 WPF可能不支持某些较新的unicode。
