mahapps中从右到左的对话框

我正在使用Mahapps，metro toolkit来创建一个WPF应用程序。我想显示一个从右到左的对话框。

await this.ShowMessageAsync("This is the title", "Some message");

我使用上面的代码来创建对话框，但它是从左到右。

Answer 1

这是如何在MessageBox中对齐。您应该使用MahApps.Metro检查是否有类似的方法来执行此操作：

MessageBox.Show("hi", "hey", MessageBoxButton.OK, MessageBoxImage.Information, MessageBoxResult.OK, MessageBoxOptions.RightAlign);

参数依次为：

• 消息
• 标题
• 按钮类型
• 显示图标
• 用户点击
返回的按钮类型
• 显示选项（这是您要查找的参数）

这将创建以下对话框：

我找到了解决方案。只需将此样式添加到app.xaml

即可

<Style TargetType="{x:Type Dialog:MessageDialog}" BasedOn="{StaticResource {x:Type Dialog:BaseMetroDialog}}"> <Setter Property="FlowDirection" Value="RightToLeft" /> </Style>

这是我的app.xaml文件

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:RandomQuestions"
         xmlns:Dialogs="clr-namespace:MahApps.Metro.Controls.Dialogs;assembly=MahApps.Metro"
         xmlns:controls="http://metro.mahapps.com/winfx/xaml/controls"
         StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary >
        <Style TargetType="{x:Type Dialogs:MessageDialog}" BasedOn="{StaticResource {x:Type Dialogs:BaseMetroDialog}}">
            <Setter Property="FlowDirection" Value="RightToLeft" />
        </Style>
        <ResourceDictionary.MergedDictionaries>
            <!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
