Here's how I disable the visual mouseover effects on buttons. I left in some of my settings just to get you a feel of how to play with the triggers and stuff, feel free to experiment!
这是我如何禁用按钮上的视觉鼠标悬停效果。我保留了一些设置只是为了让您了解如何使用触发器和其他东西，请随意尝试！
<Style TargetType="Button" x:Key="ImageButton" BasedOn="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="border"
BorderThickness="{TemplateBinding BorderThickness}"
Padding="{TemplateBinding Padding}"
BorderBrush="{TemplateBinding BorderBrush}"
CornerRadius="5"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" Value="Gainsboro" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Opacity" Value="0.25" />
<Setter Property="BorderBrush" Value="Transparent" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
EDIT: Using the "BasedOn" + setting FocusVisualStyle to null (first 2 lines) gets rid of the mouse over effects. Everything else is just examples. I added a border there in order to play with it through a trigger (since I want a custom mouseover effect).
编辑：使用“BasedOn”+ 将 FocusVisualStyle 设置为 null（前 2 行）可以消除鼠标悬停效果。其他一切都只是例子。我在那里添加了一个边框，以便通过触发器来使用它（因为我想要一个自定义的鼠标悬停效果）。

In the ControlTemplateof the Buttonthe Background property will be overridden by a trigger.
You can either redo the whole ControlTemplateand leave out the Background change or just add the image as content of your Buttonlike so to avoid all these complications:
在ControlTemplate中的Button背景属性将被触发覆盖。
您可以重做整体ControlTemplate并省略背景更改，也可以将图像添加为您Button喜欢的内容，以避免所有这些并发症：
<Button.Content>
<Image Source="button.png" />
</Button.Content>
Or if you need the text in there as well:
或者，如果您还需要那里的文字：
<Button.Content>
<Grid>
<Image Source="button.png" />
<TextBlock Text="Reset" VerticalAlignment="Center" HorizontalAlignment="Center" />
<Grid>
</Button.Content>
