鼠标悬停时如何防止 WPF 按钮模板更改所有按钮？

Question

我正在使用 WPF 模板的自定义模板。但是，在大多数情况下，当我将鼠标悬停在按钮上时，它会更改同一屏幕上所有按钮的文本颜色，这是无意的。

<Style  TargetType="{x:Type Button}">
    <Setter Property="SnapsToDevicePixels" Value="True" />
    <Setter Property="OverridesDefaultStyle"
      Value="true" />
    <Setter Property="FocusVisualStyle"
      Value="{DynamicResource ButtonFocusVisual}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border TextBlock.Foreground="{DynamicResource AlternateFontColor}"
                        TextBlock.FontFamily="Segoe UI"
                        TextBlock.FontWeight="Bold"                            
                        x:Name="Border"
                        CornerRadius="0"
                        BorderThickness="2" >
                    <Border.BorderBrush>
                        <SolidColorBrush Color="{DynamicResource ControlMouseOverColor}" />
                    </Border.BorderBrush>
                    <Border.Background>
                        <SolidColorBrush Color="{DynamicResource ColorBackgroundColor}" />
                    </Border.Background>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualStateGroup.Transitions>
                                <VisualTransition GeneratedDuration="0:0:0.0" />
                                <VisualTransition GeneratedDuration="0"
                              To="Pressed" />
                            </VisualStateGroup.Transitions>
                            <VisualState x:Name="Normal" />
                            <VisualState x:Name="MouseOver">
                                <Storyboard>
                                    <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).
                  (SolidColorBrush.Color)"

                                            Storyboard.TargetName="Border">
                                        <EasingColorKeyFrame KeyTime="0"
                                     Value="{StaticResource ControlPressedColor}" />

    </Setter>
</Style>

Answer 1

将样式声明更新为

 <Style  x:Key="buttonStyle"  TargetType="{x:Type Button}">

如果按钮必须设置样式，则为按钮分配样式

 <Button Style="{DynamicResource buttonStyle}">H2</Button>

其他按钮在声明 x:Key 后不会继承样式
