我在使用TextBox重写非常简单的MaterialDesignInXamlToolkit样式时遇到了困难。
据我所见,我一直在跟踪覆盖指令:
App.xaml
<Application x:Class="WpfApp1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
<ResourceDictionary Source="Themes/MaterialDesignTheme.Overrides.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>MainWindow.xaml
<Window x:Class="WpfApp1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:materialDesign="clr-namespace:MaterialDesignThemes.Wpf;assembly=MaterialDesignThemes.Wpf"
Title="MainWindow" Height="400" Width="300">
<Grid>
<TextBox VerticalAlignment="Center"
x:Name="NameTextBox"
materialDesign:HintAssist.Hint="Name">
</TextBox>
</Grid>
</Window>MaterialDesignTheme.Overrides.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:materialDesign="clr-namespace:MaterialDesignThemes.Wpf;assembly=MaterialDesignThemes.Wpf">
<Style x:Key="MaterialDesignTextBox"
BasedOn="{StaticResource MaterialDesignTextBox}"
TargetType="{x:Type TextBox}">
<Setter Property="FontSize" Value="200" />
</Style>
</ResourceDictionary>但是,除非我从重写文件中的样式中删除x:Key,否则文本框中的字体将保持在非常无聊的12,而不是我想要的超级令人兴奋的200。
我在Github这里上创建了一个示例项目。如果有人能看一看,我会非常感激的。

问题出现在MaterialDesignTheme.Overrides.xaml上。您指定要重写的特定样式,但不引用包含该样式的资源字典。将其合并将解决问题。
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.TextBox.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style BasedOn="{StaticResource MaterialDesignTextBox}"
TargetType="{x:Type TextBox}">
<Setter Property="FontSize" Value="200" />
</Style>
</ResourceDictionary>https://stackoverflow.com/questions/47498540
