我似乎找不到这个问题的答案。基本上，我创建了包含图像的按钮。当您将鼠标悬停在按钮上时 - 当前会出现蓝色边框。我想在图像上创建自己的悬停状态，所以我不需要蓝色边框 - 它正在推出间距。有谁知道如何删除它？

<Button Style="{StaticResource EventButton}">
    <Image Source="/Assets/EventIcons/Business/event-Fire.png" Stretch="Fill"/>
</Button>

我的风格：

<Style x:Key="RiskButton" TargetType="Button">
    <Setter Property="BorderBrush" Value="Transparent"/>
    <Setter Property="Margin" Value="4,4,4,4"/>
    <Setter Property="Width" Value="120"/>
    <Setter Property="Height" Value="120"/>
    <Setter Property="HorizontalAlignment" Value="Left"/>
    <Setter Property="Padding" Value="0"/>
    <Setter Property="BorderThickness" Value="0"/>
</Style>

谢谢你的帮助！

在 Blend for Visual Studio 下打开您的项目（我建议您之前应用 Visual Studio 2012 更新 2），选择您的按钮并右键单击 -> 编辑模板 -> 编辑副本 -> 创建新的本地资源。

在状态面板中，您将看到按钮的不同可能状态（正常、按下、指针悬停、聚焦...），例如选择“PointerOver”并将背景画笔更改为透明（或将其删除）。

PointerOver 之前：

<VisualState x:Name="PointerOver">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border" Storyboard.TargetProperty="Background">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonPointerOverBackgroundThemeBrush}" />
        </ObjectAnimationUsingKeyFrames>

        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter"                                 Storyboard.TargetProperty="Foreground">
               <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonPointerOverForegroundThemeBrush}" />
        </ObjectAnimationUsingKeyFrames>

    </Storyboard>
 </VisualState>

PointerOver 之后：

<VisualState x:Name="PointerOver">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border" Storyboard.TargetProperty="Background">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Null}" />
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter"
            Storyboard.TargetProperty="Foreground">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonPointerOverForegroundThemeBrush}" />
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</VisualState>

现在蓝色边框消失了。要将其应用于您的其他按钮，您可以在加载到 App.xaml 的字典中移动此样式并使用 Style 属性。

Windows 应用商店 XAML 框架中的每个控件都有默认的画笔和样式集。例如，这是 Button 的样式：Button styles and templates。您总是首先可以尝试将默认画笔更改为您想要的东西。如果这不会给你想要看到的效果 - 你可以在你想要的东西上更改默认控制模板。
