Answer 1

此方法允许根据一个单元格更改颜色，这可能是在特定列中执行此操作的最简单方法。请参阅以下示例：

型号：

@classmethod
def get_create_url(cls):
    return reverse_lazy('school:new-school')

<强> XAML：

public class Person
{
    public int IdPerson { get; set; }
    public string Name { get; set; }
    public string SurName { get; set; }
}

结果：

Answer 2

以下是示例代码

 <Window.Resources>
    <Style TargetType="{x:Type DataGridCell}" x:Key="MyCellStyle">
        <Style.Triggers>
            <DataTrigger Binding="{Binding Id}" Value="2">
                <Setter Property="Background" Value="LightCoral"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</Window.Resources>
<Grid Margin="10">  
    <DataGrid Name="dgUsers" AutoGenerateColumns="False">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Id" Binding="{Binding Id}" CellStyle="{StaticResource ResourceKey=MyCellStyle }" />
            <DataGridTextColumn Header="Name" Binding="{Binding Name}" />
            <DataGridTextColumn Header="Birthday" Binding="{Binding Birthday}" />
        </DataGrid.Columns>
        <DataGrid.RowDetailsTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Details}" Margin="10" />
            </DataTemplate>
        </DataGrid.RowDetailsTemplate>

    </DataGrid>
</Grid>

public class User
{
    public int Id { get; set; }

    public string Name { get; set; }

    public DateTime Birthday { get; set; }


}

    public MainWindow()
    {
        InitializeComponent();
        List<User> users = new List<User>();
        users.Add(new User() { Id = 1, Name = "John Doe", Birthday = new DateTime(1971, 7, 23) });
        users.Add(new User() { Id = 2, Name = "Jane Doe", Birthday = new DateTime(1974, 1, 17) });
        users.Add(new User() { Id = 3, Name = "Sammy Doe", Birthday = new DateTime(1991, 9, 2) });

        dgUsers.ItemsSource = users;
    }

此处单元格的值绑定到Id

的Users字段

如果单元格包含特定值，WPF DataGrid将更改单元格背景
