你知道怎么做吗？

到目前为止,这是我的风格:

<Style TargetType="{x:Type DataGrid}">
    <Setter Property="Margin" Value="5" />
    <Setter Property="Background">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="White"/>
                <GradientStop Color="AliceBlue" Offset="1"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
    <Setter Property="RowBackground">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="#BAF0FF"/>
                <GradientStop Color="PowderBlue" Offset="1"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
    <Setter Property="AlternatingRowBackground">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="White"/>
                <GradientStop Color="AliceBlue" Offset="1"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
    <Setter Property="HorizontalGridLinesBrush" Value="LightGray" />
    <Setter Property="VerticalGridLinesBrush" Value="LightGray" />
</Style>

从这个答案我能够创建这个代码,正确设置按钮的样式:

<DataGrid>    
    <DataGrid.Resources>
        <Style TargetType="Button" x:Key="{ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}">
            <Setter Property="Background" Value="Black" />
        </Style>
    </DataGrid.Resources>
</DataGrid>
