首先在App.Xaml引入相关资源
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<!--Handy Control-->
<ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/SkinDefault.xaml"/>
<ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/Theme.xaml"/>
<!--Material Design-->
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/materialdesigncolor.blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
<!--Geometry-->
<ResourceDictionary Source="pack://application:,,,/Resources/Icons/Icons.xaml"/>
<!--Custom Styles-->
<ResourceDictionary Source="pack://application:,,,/Resources/Theme/AppBaseStyles.xaml"/>
</ResourceDictionary.MergedDictionaries>
<local:AppLocator x:Key="Locator"/>
</ResourceDictionary>
</Application.Resources>
定义好DataGrid Style在引入到AppBaseStyle中， 下面是DataGrid.xaml的定义

效果如下
其它
- 在datagrid中使用ComboboxColumn时会遇到一些绑定与显示的问题， 解决方案是分别定义ComboboxColumnSytle和ComboboxColumnEditingStyle, 此方法需要麻烦但是可以解决Combobox在DataGrid中的问题
<DataGridComboBoxColumn Header="节目类型">
<DataGridComboBoxColumn.EditingElementStyle>
<Style TargetType="ComboBox">
<Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType=DataGrid}, Path=DataContext.Categories.Result}"/>
<Setter Property="DisplayMemberPath" Value="Title"/>
<Setter Property="SelectedValuePath" Value="Id"/>
<Setter Property="SelectedValue" Value="{Binding CategoryId, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>
<Setter Property="SelectedItem" Value="{Binding CategoryModel, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>
</Style>
</DataGridComboBoxColumn.EditingElementStyle>
<DataGridComboBoxColumn.ElementStyle>
<Style TargetType="ComboBox">
<Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType=DataGrid}, Path=DataContext.Categories.Result}"/>
<Setter Property="DisplayMemberPath" Value="Title"/>
<Setter Property="SelectedValuePath" Value="Id"/>
<Setter Property="SelectedValue" Value="{Binding CategoryId, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>
<Setter Property="SelectedItem" Value="{Binding CategoryModel, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>
</Style>
</DataGridComboBoxColumn.ElementStyle>
</DataGridComboBoxColumn>
- 使用MaterialDesign的DataGridComboboxColumn
<md:DataGridComboBoxColumn Header="节目类型"
ItemsSourceBinding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=DataContext.Categories.Result}"
DisplayMemberPath="Title" SelectedValuePath="Id"
SelectedValueBinding="{Binding CategoryId, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"
SelectedItemBinding="{Binding CategoryModel, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" />
