c# - header 上方的 WPF 数据网格 header

Question

所以我试图让这个数据网格更有条理:

目前我正在绑定(bind)来自 C# 代码中的 Json 文件的数据。现在我不想继续写“pilot x”、“pilot y”等等……并在这里不断重复自己。所以我想知道是否可以在当前标题之上“添加”标题。比方说，我们在一个标题下有“voornaam”、“achternaam”、“club”和“licentie”，下一个“voornaam”、“achternaam”、“club”、“licentie”也在一个标题下，然后是“merk” , "type"和 "nummerplaat"也是。

我说的“header”是这样的；

下面是XAML页面的代码；

<Grid>
        <DataGrid x:Name="list_participants" ColumnHeaderStyle="{StaticResource HeaderStyle}" ColumnWidth="Auto" RowBackground="Transparent" Foreground="#fafafa" AlternatingRowBackground="#555a62" Background="Transparent" BorderThickness="0" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Team nummer" Binding="{Binding team_number}" />
                <DataGridTextColumn Header="Voornaam" Binding="{Binding team_data.pilot.firstname}" />
                <DataGridTextColumn Header="Achternaam" Binding="{Binding team_data.pilot.lastname}" />
                <DataGridTextColumn Header="Club" Binding="{Binding team_data.pilot.club}" />
                <DataGridTextColumn Header="Licentie" Binding="{Binding team_data.pilot.license}" />
                <DataGridTextColumn Header="Voornaam" Binding="{Binding team_data.navigator.firstname}" />
                <DataGridTextColumn Header="Achternaam" Binding="{Binding team_data.navigator.lastname}" />
                <DataGridTextColumn Header="Club" Binding="{Binding team_data.navigator.club}" />
                <DataGridTextColumn Header="Licentie" Binding="{Binding team_data.navigator.license}" />
                <DataGridTextColumn Header="Merk" Binding="{Binding car_data.brand}" />
                <DataGridTextColumn Header="Type" Binding="{Binding car_data.type}" />
                <DataGridTextColumn Header="Nummerplaat" Binding="{Binding car_data.license_plate}" />
                <DataGridTemplateColumn Header="Toegelaten tot start">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox IsChecked="{Binding allowed_to_start}"/>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
                <DataGridTemplateColumn Header="Uit koers genomen">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox IsChecked="{Binding took_out_of_race}"/>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
    </Grid>

您可以在 DataGrid 上方放置一个额外的 Grid，用于额外的标题和绑定(bind)列宽:

        <StackPanel>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="{Binding ElementName=A1, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=B1, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=C1, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=A2, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=B2, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=C2, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=A3, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=B3, Path=ActualWidth, Mode=OneWay}"/>
                    <ColumnDefinition Width="{Binding ElementName=C3, Path=ActualWidth, Mode=OneWay}"/>
                </Grid.ColumnDefinitions>
                <Label Grid.ColumnSpan="3" Grid.Column="0" Content="First dude"/>
                <Label Grid.ColumnSpan="3" Grid.Column="3" Content="Second dude"/>
                <Label Grid.ColumnSpan="3" Grid.Column="6" Content="Third dude"/>
            </Grid>
            <DataGrid>
                <DataGrid.Columns>
                    <DataGridTextColumn x:Name="A1" Header="First"/>
                    <DataGridTextColumn x:Name="B1" Header="B"/>
                    <DataGridTextColumn x:Name="C1" Header="C"/>
                    <DataGridTextColumn x:Name="A2" Header="First"/>
                    <DataGridTextColumn x:Name="B2" Header="B"/>
                    <DataGridTextColumn x:Name="C2" Header="C"/>
                    <DataGridTextColumn x:Name="A3" Header="First"/>
                    <DataGridTextColumn x:Name="B3" Header="B"/>
                    <DataGridTextColumn x:Name="C3" Header="C"/>
                </DataGrid.Columns>
            </DataGrid>
        </StackPanel>

当然，就上下文菜单等而言，额外的标题不会算作 DataGrid 的一部分；如果需要，所有这些东西都必须手动添加。
