WPF-在擴展WPF工具包中自定義MessageBox的樣式

Question

為了自定義MessageBox的樣式，我使用此工具包，並從其官方頁面復制樣式代碼：

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

我改變了一點：

<Application x:Class="TotaraEditor.App"

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

            <SolidColorBrush x:Key="MyButtonHoverBrush" Color="#FF2D2D30" />
            <SolidColorBrush x:Key="MyButtonPressedBrush" Color="#FF03A9DD" />

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

                                            <Storyboard>

                                                    <DiscreteObjectKeyFrame KeyTime="00:00:00" Value="{StaticResource MyButtonHoverBrush}"></DiscreteObjectKeyFrame>
                                                </ObjectAnimationUsingKeyFrames>

                                    </VisualStateGroup>
                                </VisualStateManager.VisualStateGroups>

                                </Border>
                                <ContentPresenter x:Name="contentPresenter" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
                                <Path x:Name="path" Fill="White" Margin="0,0,0,1" Visibility="Collapsed"
                    Height="60"
        Width="7"
        Stretch="Fill"
        Opacity="1"
        Data="M 2,6 C2,6 3,6 3,6 3,6 3,5 3,5 3,5 4,5 4,5 4,5 4,6 4,6 4,6 5,6 5,6 5,6 7,6 7,6 7,6 7,5 7,5 7,5 6,5 6,5 6,5 6,4 6,4 6,4 5,4 5,4 5,4 5,2 5,2 5,2 6,2 6,2 6,2 6,1 6,1 6,1 7,1 7,1 7,1 7,0 7,0 7,0 5,0 5,0 5,0 4,0 4,0 4,0 4,1 4,1 4,1 3,1 3,1 3,1 3,0 3,0 3,0 2,0 2,0 2,0 0,0 0,0 0,0 0,1 0,1 0,1 1,1 1,1 1,1 1,2 1,2 1,2 2,2 2,2 2,2 2,4 2,4 2,4 1,4 1,4 1,4 1,5 1,5 1,5 0,5 0,5 0,5 0,6 0,6 0,6 2,6 2,6 z"/>
                            </Grid>
                        </ControlTemplate>
                    </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>

這就是我在后面的代碼中使用它的方式：

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 {...}

現在我得到的是：

由於無法觸摸這些按鈕的XAML，因此應如何更改按鈕樣式？ 至少我想刪除標題的發光效果。

謝謝。

UPDATE

我確定發光效果不是由應用於Label的某種樣式引起的，它是Label下方的樣式矩形，我在WPF Inspector中發現了這一點：

將矩形的高度設置為0后，發光的東西消失了。

您可以像這樣更改按鈕樣式：

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>

至於標題中的發光效果，您必須修改從相應發布的鏈接復制的樣式，或者創建自己的樣式。

編輯 ：使用MetroDark樣式：

    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>

編輯2：字幕發光鏈接到CaptionShadowBrush ：

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

您可以將其設置為Transparent ，或完全擺脫它：

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