c# - 更改默认按钮突出显示 WPF

Question

我试图删除 Button 上的默认背景，但是当用户将鼠标悬停在按钮上时，Button 会以橙色突出显示。到目前为止，这是我想出的；

<Window.Resources>
    <Style TargetType="{x:Type Button}">
        <Setter Property="FontSize" Value="20" />
        <Setter Property="Margin" Value="5" />
        <Setter Property="MaxHeight" Value="30" />
        <Setter Property="Width" Value="150" />
        <Setter Property="Background" Value="Transparent" />
        <Setter Property="BorderBrush" Value="Transparent" />
        <Setter Property="Cursor" Value="Hand" />
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Background" Value="Orange"/>
            </Trigger>
        </Style.Triggers>
    </Style>
</Window.Resources>

但是，当用户将鼠标悬停在按钮上时，它仍然以默认的蓝色突出显示，而不是我想要的橙色。我该如何修改它，使按钮的文本逐渐以橙色突出显示？

您需要添加ControlTemplate.Trigger:

<Style TargetType="{x:Type Button}">
 <Setter Property="FontSize" Value="20" />
 <Setter Property="Margin" Value="5" />
 <Setter Property="MaxHeight" Value="30" />
 <Setter Property="Width" Value="150" />
 <Setter Property="Background" Value="Transparent" />
 <Setter Property="Cursor" Value="Hand" />
 <Setter Property="Template">
    <Setter.Value>
       <ControlTemplate TargetType="{x:Type Button}">
          <Border Background="{TemplateBinding Background}" 
                  BorderBrush="{TemplateBinding BorderBrush}"
                  BorderThickness="{TemplateBinding BorderThickness}">
             <ContentPresenter HorizontalAlignment="Center" 
                               VerticalAlignment="Center"/>
          </Border>
           <ControlTemplate.Triggers>
                <Trigger Property="IsMouseOver" 
                          Value="True">
                   <Setter Property="Background" 
                           Value="Orange"/>
                </Trigger>
        </ControlTemplate.Triggers>
       </ControlTemplate>
    </Setter.Value>
 </Setter>
