Question

通过多重绑定，我能够设置特定细胞的背景。但是，我想将单元格文本的水平对齐设置为右边，但这会混淆应该拉伸整个背景的背景颜色（而不仅仅是对齐的文本））：

bad background

这是缩小（可运行）代码

public partial class MainWindow : Window
{
    public ObservableCollection<Test> MyData { get; set; }

    public MainWindow()
    {
        InitializeComponent();

        DataContext = this;
        MyData = Test.GetData();
    }
}

public class Test
{
    public string Title { get; set; }
    public string ColOne { get; set; }
    public string ColTwo { get; set; }

    public static ObservableCollection<Test> GetData()
    {
        return new ObservableCollection<Test>
        {
            new Test { Title = "HO", ColOne = "3.20", ColTwo = "5.85"},
            new Test { Title = "DOR", ColOne = "-3.33", ColTwo = "5.9"}
        };
    }
}

和XAML

<Window x:Class="ColorColumnAlignment.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DataGrid ItemsSource="{Binding Path=MyData}">
            <DataGrid.Resources>
                <Style TargetType="DataGridCell">
                    <Style.Setters>
                        <Setter Property="HorizontalAlignment" Value="Right"></Setter>
                        <Setter Property="Background" Value="Chocolate"></Setter>
                    </Style.Setters>
                </Style>
            </DataGrid.Resources>
        </DataGrid>
    </Grid>
</Window>

我见过有类似问题的人，但我不明白他试图解释的是他的解决方案（WPF: DataGridCell override the row style color）

- 更新：设置HorizontalContentAlignment完全没有不帮助，导致这个（右边的对齐方式已经消失了）：

Stays aligned left

将您的TargetType和Setter属性更改为以下修改后的代码中的示例：

<Window x:Class="ColorColumnAlignment.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DataGrid ItemsSource="{Binding Path=MyData}">
            <DataGrid.Resources>
                <Style TargetType="{x:Type TextBlock}">
                    <Style.Setters>
                        <Setter Property="TextAlignment" Value="Right" />
                        <Setter Property="Background" Value="Chocolate" />
                    </Style.Setters>
                </Style>
            </DataGrid.Resources>
        </DataGrid>
    </Grid>
</Window>

我找到了这个解决方案：

<Style TargetType="{x:Type DataGridCell}">
    <Setter Property="Foreground" Value="{StaticResource Text}"/>
    <Setter Property="Background" Value="{StaticResource Foreground}"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
                <Grid Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
