WPF - 在扩展 WPF 工具包中自定义 MessageBox 的样式

Question

为了自定义MessageBox的样式，我使用了这个工具包，我从它的官方页面复制了样式代码：

http://wpftoolkit.codeplex.com/wikipage?title=MessageBox&referringTitle=Documentation

我稍微改了一下：

<Application x:Class="TotaraEditor.App"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

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

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

                                </VisualStateManager.VisualStateGroups>

                                <Path x:Name="path" Fill="White" Margin="0,0,0,1" Visibility="Collapsed"
                    Height="60"

                            </Grid>

                    </Setter.Value>
                </Setter>
            </Style>

            <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>

这是我在后面的代码中使用它的方式：

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：

由于无法触摸这些按钮的 XAML，我应该如何更改按钮样式？至少我想去掉头部的发光效果。

谢谢。

更新

我确定发光效果不是由应用于标签的某些样式引起的，它是标签下方的一个带样式的矩形，我在 WPF Inspector 中找到了这个：

在我将该矩形的高度设置为 0 后，那个发光的东西就消失了。

Answer 1

您可以像这样更改按钮样式：

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>

至于标题中的发光效果，您必须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：

    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：标题发光链接到CaptionShadowBrush：

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

您可以将其设置为 Transparent，或完全删除它：

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