WPF - 在 Extended WPF Toolkit 中自定义 MessageBox 的样式

3
为了定制MessageBox的样式,我使用了这个工具包,并从官方页面复制了样式代码:http://wpftoolkit.codeplex.com/wikipage?title=MessageBox&referringTitle=Documentation
我稍微修改了一下:
<Application x:Class="TotaraEditor.App"

            <SolidColorBrush x:Key="MyButtonPressedBrush" Color="#FF03A9DD" />

            <Style x:Key="MyCloseButtonStyle" TargetType="Button">

            <Style TargetType="{x:Type toolkit:MessageBox}">
                <Setter Property="Background" Value="#FF1E1E1E" />
                <Setter Property="BorderBrush" Value="#FF999999" />
                <Setter Property="CaptionForeground" Value="#FFF1F1F1" />
                <Setter Property="WindowBorderBrush" Value="#FF686868" />
                <Setter Property="WindowBackground" Value="#FF2D2D30" />
                <Setter Property="WindowOpacity" Value="0.3" />
                <Setter Property="Foreground" Value="#FFF1F1F1"/>
                <Setter Property="CloseButtonStyle" Value="{StaticResource MyCloseButtonStyle}"/>
            </Style>



        </ResourceDictionary>

    </Application.Resources>
</Application>

这是我在代码后端中如何使用它:
var res = Xceed.Wpf.Toolkit.MessageBox.Show( 
                            "R U sure?", 
                            "Confirm dialog", 
                            MessageBoxButton.YesNoCancel, 
                            MessageBoxImage.None, 
                            MessageBoxResult.Cancel, 
                            null 
                        ); 
if ("Cancel" == res.ToString()) {...} 
else if ("No" == res.ToString()) {...} 
else if ("Yes" == res.ToString()) {...} 
else {...}

现在我得到的是:enter image description here 由于无法触及这些按钮的XAML,我应该如何更改按钮样式?至少我想要去掉标题的发光效果。
谢谢。
更新: 我确定那个发光效果不是由于应用于标签的某些样式所致,而是标签下面的一个经过处理的矩形。我在WPF Inspector中发现了这一点:enter image description here
当我将该矩形的高度设置为0时,那个发光效果消失了。

您可以像这样更改按钮样式:

enter image description here

private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        Xceed.Wpf.Toolkit.MessageBox mbox = new Xceed.Wpf.Toolkit.MessageBox();
        mbox.OkButtonStyle = (Style)Resources["ButtonStyle1"];
        mbox.OkButtonContent = "Click Me !";
        mbox.Caption = "My custom caption";
        mbox.Text = "My custom message";
        mbox.ShowDialog();
    }

XAML:

    <Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Green"></Setter>
        <Setter Property="Foreground" Value="White"></Setter>
    </Style>

关于标题中的发光效果,您需要相应地修改从您发布的链接中复制的样式,或者创建自己的样式。
编辑:使用 MetroDark 样式:

enter image description here

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        var res = Xceed.Wpf.Toolkit.MessageBox.Show(
                           "R U sure?",
                           "Confirm dialog",
                           MessageBoxButton.YesNoCancel,
                           MessageBoxImage.None,
                           MessageBoxResult.Cancel,
                           (Style)Resources["MessageBoxStyle1"]
                       );

        if ("Cancel" == res.ToString())
        {
        }
        else if ("No" == res.ToString())
        {
        }
        else if ("Yes" == res.ToString())
        {
        }
        else
        {
        }
    }

XAML:

        <Style x:Key="ButtonStyle1" TargetType="Button">
            <Setter Property="Background" Value="LightGreen"></Setter>
            <Setter Property="Foreground" Value="DarkGreen"></Setter>
        </Style>
        <Style x:Key="ButtonStyle2" TargetType="Button">
            <Setter Property="Background" Value="LightCoral"></Setter>
            <Setter Property="Foreground" Value="DarkRed"></Setter>
        </Style>
        <Style x:Key="ButtonStyle3" TargetType="Button">
            <Setter Property="Background" Value="LightYellow"></Setter>
            <Setter Property="Foreground" Value="DarkOrange"></Setter>
        </Style>

        <Style x:Key="MessageBoxStyle1" TargetType="{x:Type xctk:MessageBox}">
            <Setter Property="Background" Value="#FF1E1E1E" />
            <Setter Property="BorderBrush" Value="#FF999999" />
            <Setter Property="CaptionForeground" Value="#FFF1F1F1" />
            <Setter Property="WindowBorderBrush" Value="#FF686868" />
            <Setter Property="WindowBackground" Value="#FF2D2D30" />
            <Setter Property="WindowOpacity" Value="0.3" />
            <Setter Property="Foreground" Value="#FFF1F1F1"/>
            <Setter Property="CloseButtonStyle" Value="{StaticResource MyCloseButtonStyle}"/>
            <Setter Property="YesButtonStyle" Value="{StaticResource ButtonStyle1}"></Setter>
            <Setter Property="NoButtonStyle"  Value="{StaticResource ButtonStyle2}"></Setter>
            <Setter Property="CancelButtonStyle" Value="{StaticResource ButtonStyle3}"></Setter>
        </Style>

编辑2:标题发光效果与CaptionShadowBrush相关联:

        <Setter Property="CaptionShadowBrush" Value="LightCoral"></Setter>

enter image description here

你可以将其设置为透明,或者完全去掉它:
        <Setter Property="CaptionShadowBrush" Value="Transparent"></Setter>

谢谢jstreet,我更新了问题,正如您所看到的,在样式的代码片段中,我没有看到任何与发光效果相关的内容,大部分代码都是关于按钮样式的。 - VincentZHANG
@VincentZHANG,请将样式作为文本发布,而不是作为屏幕截图,这样人们就可以复制它。此外,请将代码从您的评论中移动到您的帖子中,并明确您需要什么。 - jsanalytics
因为您正在调用MessageBox.Show(),这是一个static方法,所以您无法设置任何Style。顺便说一下,当我运行您的代码时,我得到了一个没有任何Style的普通MessageBox,所以肯定有一些您没有向我们展示的东西。如果我强制使用您发布的样式,它与您展示的消息框的打印屏幕并不完全对应;没有发光效果。因此,在您发布的代码和结果之间存在不一致的地方。 - jsanalytics
能否去掉灰色边框? - daniel
@daniel:将ButtonRegionBackground设置为Transparent或任何您想要的颜色。 - jsanalytics
