MahApps - 如何禁用默认按钮的自动大写

Question

我已经开始在我的WPF应用程序中引入 MahApps.Metro（真的很棒），而且我最喜欢的按钮是默认的。问题是，它把所有的文本都变成大写，而我不想要。

Answer 1

您可以通过在Window.Resources中设置所有按钮的属性来覆盖默认值。

    <controls:MetroWindow
    ...
    xmlns:controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
        <Window.Resources>
            <ResourceDictionary>
                <Style TargetType="{x:Type Button}" 
                       BasedOn="{StaticResource {x:Type Button}}">
                    <Setter Property="controls:ButtonHelper.PreserveTextCase" Value="True"/>
                </Style>
            </ResourceDictionary>
        </Window.Resources>
        <Grid>
             <!-- This would have normally made the text uppercase if not for the style override -->
             <Button Content="Button"/>
        </Grid>
    </controls:MetroWindow>

省略 x:Key 设置会导致该样式应用于此 MetroWindow 中的所有按钮。

我觉得MahApps.Metro默认不应该使用大写字母，但感谢您提供的解决方案。它非常好用。 - mababin

你也可以使用 "http" mahapps 命名空间: xmlns:controls="http://metro.mahapps.com/winfx/xaml/controls"。当然，你需要在项目中安装mahapps包。 - heltonbiker

如何保留所有内容的原始大小写？“正常大小写”不应该是正常情况吗？！ - Leon

ButtonHelper.PreserveTextCase现在被替换为ControlsHelper.ContentCharacterCasing。 - Kux

Answer 2

如果您将ImaBrokeDude的答案应用到您的App.xaml中，它将适用于项目中任何窗口中的所有按钮。

<Application 
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro">
<Application.Resources>
    <ResourceDictionary>
        <Style TargetType="{x:Type Button}" 
                   BasedOn="{StaticResource {x:Type Button}}">
            <Setter Property="controls:ButtonHelper.PreserveTextCase" Value="True"/>
        </Style>     
    </ResourceDictionary>       
</Application.Resources>

在设计器中看起来很好，但在运行时，按钮样式回退到默认的WPF样式。 - tm1

ButtonHelper.PreserveTextCase现在被ControlsHelper.ContentCharacterCasing所取代。 我发现BasedOn = "{StaticResource MahApps.Styles.Button}"似乎可以工作。 - Kux

MahApps 2.4.7 更新

<Application 
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:controls="http://metro.mahapps.com/winfx/xaml/controls">
<Application.Resources>
    <ResourceDictionary>
        <Style TargetType="{x:Type Button}" 
                   BasedOn="{StaticResource MahApps.Styles.Button}">
            <Setter Property="controls:ControlsHelper.ContentCharacterCasing" Value="True"/>
        </Style>     
    </ResourceDictionary>       
</Application.Resources>

我认为应该是<Setter Property="controls:ControlsHelper.ContentCharacterCasing" Value="Normal"/>。 - Mohamed Boulmers

Answer 4

以下代码对我有效： <Setter Property="mah:ControlsHelper.ContentCharacterCasing" Value="Normal"/> 我必须使用名称空间“mah”而不是“controls”，以匹配当前快速入门指南的说明。从 XML 片段中使其工作有点棘手，因为它们需要与代码中的其他指令保持一致。下面是一个完整的工作示例。

App.xml:

<Application x:Class="Example.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:Example"
             xmlns:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <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" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
                <!-- Theme setting -->
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Dark.Blue.xaml" />
            </ResourceDictionary.MergedDictionaries>
            <!-- Change default Button character case from Upper to Normal -->
            <Style TargetType="{x:Type Button}" BasedOn="{StaticResource MahApps.Styles.Button}">
                <Setter Property="mah:ControlsHelper.ContentCharacterCasing" Value="Normal"/>
            </Style>
        </ResourceDictionary>
    </Application.Resources>
</Application>

MainWindow.xml:

<mah:MetroWindow x:Class="Example.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Example"
        mc:Ignorable="d"
        xmlns:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        TitleCharacterCasing="Normal"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Button Content="Button"  HorizontalAlignment="Left" Margin="92,73,0,0" VerticalAlignment="Top" Height="144" Width="197" FontSize="22" />
    </Grid>
</mah:MetroWindow>
