更改默認按鈕突出顯示WPF

Question

我想刪除一個默認的背景Button ，但隨后突出Button橙色當用戶將鼠標懸停在用鼠標按鈕。 這是我到目前為止所提出的;

<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，當用戶將鼠標懸停在按鈕上時，它會以默認的藍色突出顯示，而不是我想要的橙色。 如何修改它以使Button的文本逐漸以橙色突出顯示？

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>
