c# - 在 WPF DataGrid 中合并单元格

Question

我想创建一个跨越一列中多行的 WPF 数据网格。像这样:

+-------+----------------+
| Name  | Attributes     |
+-------+----------------+
|       | Horse Power    |
| BMW   +----------------+
|       | Color          |
+-------+----------------+
|       | Weight         |
| Ford  +----------------+
|       | Color          |
+-------+----------------+

下面的代码怎么改才能搞定？

<DataGrid AutoGenerateColumns="False">
     <DataGrid.Columns>
          <DataGridTextColumn Header="Name" />
          <DataGridTextColumn Header="Attributes" />
     </DataGrid.Columns>
</DataGrid>

Answer 1

尝试使用 DataGridTemplateColumn。我为数据绑定(bind)创建了示例测试类

public class Test
{

    public Test(string name, string attribute1, string attribute2)
    {
        Name = name;
        Attributes = new Attribute(attribute1, attribute2);
    }

    public string Name { get; set; }
    public Attribute Attributes { get; set; }
}

public class Attribute
{

    public Attribute(string attribute1, string attribute2)
    {
        Attribute1 = attribute1;
        Attribute2 = attribute2;
    }

    public string Attribute1 { get; set; }
    public string Attribute2 { get; set; }
}

还有 xaml 中的数据网格

<DataGrid AutoGenerateColumns="False"  Name="dataGrid1" ItemsSource="{Binding}">
        <DataGrid.Columns>
            <DataGridTemplateColumn Header="Name"  >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <Grid>
                            <TextBlock Text="{Binding Path=Name}"  VerticalAlignment="Center" Margin="3,3,3,3"/>
                        </Grid>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
            <DataGridTemplateColumn Header="Attributes"  >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate >
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="50*"/>
                                <RowDefinition />
                                <RowDefinition Height="50*"/>
                            </Grid.RowDefinitions>
                            <TextBlock Grid.Row="0" Text="{Binding Path=Attributes.Attribute1}" VerticalAlignment="Center" Margin="3,3,3,3"/>
                            <Line Grid.Row="1" Stroke="Black" Stretch="Fill" X2="1" VerticalAlignment="Center"/>
                            <TextBlock Grid.Row="2" Text="{Binding Path=Attributes.Attribute2}"  VerticalAlignment="Center" Margin="3,3,3,3"/>
                        </Grid>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

并在code-behind中填写

List<Test> list = new List<Test>();
//populate list with your data here
dataGrid1.DataContext = list;
