Question

根据答案here，为了设置数据网格左上角的样式（全部选择按钮），我可以这样做：

<Style TargetType="{x:Type Button}"
       x:Key="{ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, 
  TypeInTargetAssembly={x:Type DataGrid}}">
    <Setter Property="BorderBrush" Value="#FFf2f2f2"/>
    <Setter Property="BorderThickness" Value="0, 0, 1, 0"/>
    <Setter Property="Background" Value="#FFf9f9f9"/>
</Style>

问题是，我不想全局这种风格，但我确实希望能够重复使用这种风格。我知道我可以将其复制/粘贴到特定的数据网格中，但我更愿意保持它可重用。这可能是通过某种方式将属性应用于数据网格吗？

试试这个：

                                            <Grid.ColumnDefinitions>
                                                <ColumnDefinition Width="{Binding NonFrozenColumnsViewportHorizontalOffset, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"/>

</Window.Resources>

<Window.DataContext>
    <local:MyViewModel/>
</Window.DataContext>

<Grid>
    <StackPanel>
        <DataGrid x:Name="dataGrid1" ItemsSource="{Binding Data}" Style="{DynamicResource DataGridStyle1}" />
        <DataGrid x:Name="dataGrid2" ItemsSource="{Binding Data}"/>
    </StackPanel>
</Grid>

您还可以通过仅自定义数据网格Template来减少冗长：

    <Style TargetType="{x:Type Button}"
           x:Key="SelectAllButtonStyle1">
        <Setter Property="BorderBrush" Value="#FFf2f2f2"/>
        <Setter Property="BorderThickness" Value="0, 0, 1, 0"/>
        <Setter Property="Background" Value="Red"/>
    </Style>

    <ControlTemplate x:Key="ControlTemplate1" TargetType="{x:Type DataGrid}">
        <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True">
            <ScrollViewer x:Name="DG_ScrollViewer" Focusable="false">
                <ScrollViewer.Template>
                    <ControlTemplate TargetType="{x:Type ScrollViewer}">
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto"/>
                                <ColumnDefinition Width="*"/>
                                <ColumnDefinition Width="Auto"/>
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto"/>
                                <RowDefinition Height="*"/>
                                <RowDefinition Height="Auto"/>
                            </Grid.RowDefinitions>
                            <Button Command="{x:Static DataGrid.SelectAllCommand}" Focusable="false" Style="{DynamicResource SelectAllButtonStyle1}" Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.All}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" Width="{Binding CellsPanelHorizontalOffset, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"/>
                            <DataGridColumnHeadersPresenter x:Name="PART_ColumnHeadersPresenter" Grid.Column="1" Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.Column}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"/>
                            <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" Grid.ColumnSpan="2" Grid.Row="1"/>
                            <ScrollBar x:Name="PART_VerticalScrollBar" Grid.Column="2" Maximum="{TemplateBinding ScrollableHeight}" Orientation="Vertical" Grid.Row="1" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}"/>
                            <Grid Grid.Column="1" Grid.Row="2">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="{Binding NonFrozenColumnsViewportHorizontalOffset, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"/>
                                    <ColumnDefinition Width="*"/>
                                </Grid.ColumnDefinitions>
                                <ScrollBar x:Name="PART_HorizontalScrollBar" Grid.Column="1" Maximum="{TemplateBinding ScrollableWidth}" Orientation="Horizontal" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportWidth}"/>
                            </Grid>
                        </Grid>
                    </ControlTemplate>
                </ScrollViewer.Template>
                <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
            </ScrollViewer>
        </Border>
    </ControlTemplate>

然后像以前一样同样地应用它：

    <StackPanel>
        <DataGrid x:Name="dataGrid1" 
                  ItemsSource="{Binding Data}" 
                  Template="{DynamicResource ControlTemplate1}" />
        <DataGrid x:Name="dataGrid2" 
                  ItemsSource="{Binding Data}" />
    </StackPanel>

xaml style all datagrid＆＃39; select all＆＃39;特定样式名称的按钮
