与此相关的问题：数据网格样式表 - 左上角。

我有一个的DataGrid （尚未完成，原谅样式）。我怎样才能改变使用XAML（如在其他问题而不是C＃）？

I have a DataGrid (not finished yet, excuse the styles). How can I change the background colour of the top-left corner using XAML (as opposed to C# in the other question)?

下面是我当前的XAML：

Here's my current XAML:

<DataGrid x:Name="DataGrid" HorizontalAlignment="Center" VerticalAlignment="Center"
          ColumnWidth="100" ColumnHeaderHeight="50" RowHeight="50" RowHeaderWidth="115" Padding="5"
          BorderBrush="#FF646464" FontSize="18" FontFamily="Segoe UI"
          CanUserReorderColumns="False" CanUserResizeColumns="False" CanUserSortColumns="False" CanUserResizeRows="False"
          Focusable="False" IsEnabled="False" IsReadOnly="True">
    <DataGrid.Background>
        <SolidColorBrush Color="#FFFFFFC8"/>
    </DataGrid.Background>
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding In}" Header="In"/>
        <DataGridTextColumn Binding="{Binding Out}" Header="Out"/>
        <DataGridTextColumn Binding="{x:Null}" Header="Hours"/>
    </DataGrid.Columns>
    <DataGrid.ColumnHeaderStyle>
        <Style TargetType="{x:Type DataGridColumnHeader}">
            <Setter Property="Background" Value="#FFFFFFC8"/>
            <Setter Property="BorderBrush" Value="DarkSlateGray"/>
            <Setter Property="BorderThickness" Value="1, 2"/>
            <Setter Property="FontWeight" Value="SemiBold"/>
            <Setter Property="HorizontalContentAlignment" Value="Center"/>
            <Setter Property="Padding" Value="5"/>
        </Style>
    </DataGrid.ColumnHeaderStyle>
    <DataGrid.RowBackground>
        <SolidColorBrush Color="Transparent"/>
    </DataGrid.RowBackground>
    <DataGrid.RowHeaderStyle>
        <Style TargetType="{x:Type DataGridRowHeader}">
            <Setter Property="Background" Value="#FFFFFFC8"/>
            <Setter Property="BorderBrush" Value="DarkSlateGray"/>
            <Setter Property="BorderThickness" Value="2, 1"/>
            <Setter Property="FontWeight" Value="SemiBold"/>
            <Setter Property="Padding" Value="5"/>
        </Style>
    </DataGrid.RowHeaderStyle>
    <DataGrid.RowHeaderTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGridRow}}, Path=Item.Day}"/>
        </DataTemplate>
    </DataGrid.RowHeaderTemplate>
</DataGrid>

奖励：？我怎样才能得到行/列标题2px的边框那里有目前只有1px的边框

Bonus: how can I get a 2px border on the row/column headers where there's currently only a 1px border?

推荐答案

右键因此，如果我们去检查了的默认模板和我们看到的第一个code例子的最顶端;

Right so if we go check out the Default Template and at the very top of the first code example we see;

＆LT;！ - 风格和模板在DataGrid的左上角。 - ＆GT按钮;

通过的声明样式模板;

With the declared style template of;

＆LT;风格的TargetType ={X：类型按钮}        X：关键={ComponentResourceKey RESOURCEID = DataGridSelectAllButtonStyle，   TypeInTargetAssembly = {X：类型的DataGrid}}＆GT;

<Style TargetType="{x:Type Button}" x:Key="{ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}">

我们现在知道什么/在哪里。之后，它的编辑只是一个问题说风格一部分，我们的心内容和压倒一切的在实例级别或模板等。

We now know what/where it is. After that it's just a matter of editing said style part to our hearts content and overriding at the instance level or at the template etc.

至于你的奖金问题，如果我们去看看相同的样式模板的＆LT;风格的TargetType ={X：类型DataGridRowHeader}＆GT; 我们'会看到硬设置了borderThickness 在 X：名称=rowHeaderBorder，我们将只改变什么。其中，同样适用于＆LT;风格的TargetType ={X：类型DataGridColumnHeader}＆GT; 模板，另外还有其它硬盘设置了borderThickness X：名称=columnHeaderBorder

As for your bonus question, if we go check out the same style templates at the <Style TargetType="{x:Type DataGridRowHeader}"> we'll see hard-set BorderThickness on the x:Name="rowHeaderBorder" that we'll just change to whatever. Wherein the same applies to the <Style TargetType="{x:Type DataGridColumnHeader}"> template as there's also another hard-set BorderThickness of "1" on the x:Name="columnHeaderBorder"

希望这会有所帮助，干杯！

Hope this helps, cheers!
