如何使鼠标移入button时button不显示高亮变色效果？

Question

请问大家如何做才能使当鼠标移到Button上时，Button不会高亮显示并且变色，而是还是显示原来的背景色，谢谢！

这个根本原因是WPF button在默认的template里面做的效果，要想disable掉 最直接的就是改template或者重写

<Button Content="AAA" MouseEnter="Button_MouseEnter_1">
    <Button.Template>
        <ControlTemplate TargetType="Button">
            <Border Name="border" 
                    BorderThickness="1"
                    Padding="4,2" 
                    BorderBrush="DarkGray" 
                    CornerRadius="3" 
                    Background="{TemplateBinding Background}">
                <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
            </Border>
                   
        </ControlTemplate>
    </Button.Template>
</Button>

如果你想要保持Button原来的样子（例如XP里面显示XP的按钮，Windows Aero Glass中显示Aero Glass样式的按钮，Basic中显示Basic样式的按钮）并阻止变色，你需要绘制这个控件而不是使用样式：

在构造方法中调用这个方法：

private void CreateStaticButton()
{
    Button button = new Button();
    button.Height = 100;
    button.Width = 100;
    button.Content = "hello, world";
    button.UpdateLayout();
    rect.Fill = new VisualBrush(button) { Stretch = Stretch.None };
    rect.UpdateLayout();
}

XAML的内容是：

<Window x:Class="WPFButtonDontChangeColourWhenPointerOver.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Rectangle Name="rect" />
    </Grid>
</Window>

如果你不需要保留系统默认的Button样式，你可以使用这个例子，它创建一个默认的Windows 应用商店应用的亮色按钮的样式（嘿，在WPF里面做些类似Store的东西也挺酷的，不是么？）已经删除了指针移到上方时的变色效果。

        <Button Height="60" Width="100">
            <Button.Style>
                <Style TargetType="ButtonBase">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="ButtonBase">
                                <ControlTemplate.Resources>
                                    <Storyboard x:Key="pressedStoryboard">
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="border" Storyboard.TargetProperty="BorderBrush">
                                            <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Null}" />
                                        </ObjectAnimationUsingKeyFrames>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="border" Storyboard.TargetProperty="Background">
                                            <DiscreteObjectKeyFrame KeyTime="0">
                                                <DiscreteObjectKeyFrame.Value>
                                                    <SolidColorBrush Color="Black" />
                                                </DiscreteObjectKeyFrame.Value>

                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground)">
                                            <DiscreteObjectKeyFrame KeyTime="0">

                                        </Trigger.EnterActions>
                                        <Trigger.ExitActions>
                                            <BeginStoryboard Storyboard="{StaticResource revokePressedStoryboard}" />
                                        </Trigger.ExitActions>
                                    </Trigger>
                                </ControlTemplate.Triggers>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </Button.Style>
            <Button.Content>hello, world</Button.Content>
        </Button>

我的建议：在你的应用中保持风格统一，如果要舍弃原来系统默认的样式，请全部改用相同的样式。

另外，这个需求着实奇怪，为什么在指针移入按钮的时候不给用户视觉反馈呢？

十分感谢大家的帮助，问题已解决，之所以有这个需求，是因为项目中当鼠标移到类似win8的色块按钮上时，会高亮显示用户觉得不好看。再一次谢谢大家！
