• Wpf之HandyControls与MaterialDesign混用之DataGrid

    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
    <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                    xmlns:hc="https://handyorg.github.io/handycontrol">

    效果如下

    其它
    1. 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>
    1. 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}" />
