c# - 在WPF MVVM应用程序中添加 Material 设计后，数据网格不显示滚动条，并且设计变得过时

Question

我在WPF MVVM应用程序中同时使用了 Material 设计和dragablz:TabablzControl。 Material 设计用于设置按钮和文本框的样式。网格位于选项卡控件内部。将批量数据加载到数据网格中后，我面临以下设计问题。

它不显示滚动条。我曾经尝试过使用滚动查看器
它没有用。其实我可以使用箭头键和鼠标向下滚动
滚动。但是滚动条不可见。

当我们单击数据网格的单行时，该行变得不可见或褪色。

当我们单击网格标题时，它将选择所有行

窗口中显示一条虚线。

任何解决问题的方法。我如何才能只针对数据网格进行 Material 设计。

Answer 1

我认为您看不到某些控件或出现奇怪的外观(如怪异的颜色褪色)的原因是控件的颜色。
Material 设计主题基于或由几种资源组成。这样可以灵活地定制最终主题。
您基本上具有可以组合的控件设计主题和颜色主题。
但是您始终需要导入设计和颜色主题相结合的适当资源。MaterialDesignTheme.Defaults.xaml包含基本或共享的主题资源，这些资源主要是设计的，与颜色无关，例如控件的默认样式。您已成功合并此资源。
但是您错过了将颜色主题合并到ResourceDictionary的过程。
例如，您需要导入MaterialDesignTheme.Dark.xaml的深色基础主题:

<ResourceDictionary.MergedDictionaries>
  <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />

  <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml" />
</ResourceDictionary.MergedDictionaries>

另外，您也可以使用 BundledTheme合并颜色主题，它可以通过在单个 BundledTheme对象中设置相关属性(例如主强调色)来合并相关的配色方案:

<ResourceDictionary.MergedDictionaries>
  <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />

  <materialDesign:BundledTheme BaseTheme="Dark" 
                               PrimaryColor="Yellow" 
                               SecondaryColor="Red" />
</ResourceDictionary.MergedDictionaries>
