我是新手，Styles不确定创建Button样式以更改andForeground的最佳方法。我将 a用于模板，因为它具有 a和背景以及边框属性。但没有财产。由于默认外观没有被覆盖，因此用作模板效果不佳。IsMouseOverIsPressedBorderCornerRadiusBorderForegroundButton

用行为设置Button模板样式的更好方法是什么？Foreground也许在边界内使用标签？

这是 App.xaml：

<Application.Resources>
    <Style TargetType="Button" x:Key="MyButton">
        <Setter Property="SnapsToDevicePixels" Value="true"/>
        <Setter Property="OverridesDefaultStyle" Value="true"/>
        <Setter Property="MinHeight" Value="34"/>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="shortcutbutton"  
                    BorderThickness="1"
                    BorderBrush="Black"
                    Background="Gray">
                        <ContentPresenter Margin="2" 
                                  HorizontalAlignment="Center"
                                  VerticalAlignment="Center" 
                                  RecognizesAccessKey="True"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter TargetName="shortcutbutton" Property="Background" Value="#FFDADADA" />
                            <Setter TargetName="shortcutbutton" Property="BorderBrush" Value="#EEEEEE" />
                            <!--<Setter TargetName="Border" Property="Foreground" Value="Black" />-->
                        </Trigger>
                        <Trigger Property="IsPressed" Value="true">
                            <Setter TargetName="shortcutbutton" Property="Background" Value="DarkGray" />
                            <Setter TargetName="shortcutbutton" Property="BorderBrush" Value="Black" />
                            <!--<Setter TargetName="Border" Property="Foreground" Value="Red" />-->
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Application.Resources>

和 xaml：

    <StackPanel HorizontalAlignment="Center" Height="100" VerticalAlignment="Center" Width="100">
        <Button Content="Button" Height="41" Style="{DynamicResource MyButton}"/>
    </StackPanel>

您需要将触发器从 ControlTemplate 移动到 Style。像这样的东西：

        <Style TargetType="Button">
        <Setter Property="SnapsToDevicePixels" Value="true"/>
        <Setter Property="OverridesDefaultStyle" Value="true"/>
        <Setter Property="MinHeight" Value="34"/>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="shortcutbutton"  
                BorderThickness="1"
                BorderBrush="Black"
                Background="Gray">
                        <ContentPresenter Margin="2" 
                              HorizontalAlignment="Center"
                              VerticalAlignment="Center" 
                              RecognizesAccessKey="True"/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="true">
                <Setter Property="Foreground" Value="#FFDADADA" />
            </Trigger>
            <Trigger Property="IsPressed" Value="true">
                <Setter Property="Foreground" Value="DarkGray" />
            </Trigger>
        </Style.Triggers>
    </Style>

您可以做的是设置附加属性，TextElement并且Border您的每个文本元素都Border将具有该颜色：

<ControlTemplate.Triggers>
   <Trigger Property="IsMouseOver" Value="true">
       <Setter TargetName="shortcutbutton" Property="Background" Value="#FFDADADA" />
       <Setter TargetName="shortcutbutton" Property="BorderBrush" Value="#EEEEEE" />
       <Setter TargetName="shortcutbutton" Property="TextElement.Foreground" Value="White"/>
   </Trigger>
   ...
</ControlTemplate.Triggers>
