提问by Vivek Saurav
I have a DataGridwhich needs to look like this:
我有一个DataGrid需要看起来像这样：
As you can see, there are multiple columns as well as multi-level column headers, some that span multiple columns.
如您所见，有多个列以及多级列标题，其中一些跨越多个列。
I need to do this in WPF, so kindly provide only XAML solutions which will create multi level column headers.
我需要在 WPF 中执行此操作，因此请仅提供将创建多级列标题的 XAML 解决方案。

As far as I know, the standard DataGriddoes not support it, so you need to look for alternatives. I can offer the use of a Gridcapabilities, such as: Grid.RowDefinitions, Grid.ColumnDefinitions. To illustrate this feature, I created a sample, who need to complete:
据我所知，标准DataGrid不支持它，所以你需要寻找替代品。我可以提供使用Grid功能，例如：Grid.RowDefinitions，Grid.ColumnDefinitions。为了说明这个特性，我创建了一个示例，需要完成：
<Window x:Class="MultiHeaderDataGrid.MainWindow"

<Setter Property="TextBlock.FontSize" Value="14" />
<Setter Property="BorderBrush" Value="Black" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="HorizontalAlignment" Value="Stretch" />
</Style>
</Window.Resources>

</Grid>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />

<Grid Grid.Row="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Border Grid.Column="0">
<TextBlock Grid.Column="1" Text="Mode 1" TextAlignment="Center" />
</Border>
<Border Grid.Column="1">
<TextBlock Grid.Column="1" Text="Mode 2" TextAlignment="Center" />
</Border>
<Border Grid.Column="2">
<TextBlock Grid.Column="1" Text="Mode 1" TextAlignment="Center" />
</Border>
<Border Grid.Column="4">
<TextBlock Grid.Column="1" Text="Mode 2" TextAlignment="Center" />
</Border>
</Grid>
<Grid Grid.Row="3">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />

<Border Grid.Column="4">
<TextBlock Grid.Column="1" Text="Mode 2" TextAlignment="Center" />
</Border>
</Grid>
<DataGrid Name="datagrid1" AutoGenerateColumns="False" Grid.Row="3" RowHeaderWidth="10" Loaded="datagrid1_Loaded">
<DataGrid.Columns>
<DataGridTextColumn x:Name="Column1" Binding="{Binding Name}" Header="column 1" Width="100" />
<DataGridTextColumn x:Name="Column2" Binding="{Binding Age}" Header="column 2" Width="80" />
<DataGridTextColumn x:Name="Column3" Binding="{Binding Sample}" Header="column 3" Width="80" />
<DataGridTextColumn x:Name="Column4" Binding="{Binding Sample}" Header="column 4" Width="*" />
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>

If you want, you can set the ColumnDefinition Widthof a Grid, like a DataGridcolumn:
如果你愿意，你可以设置ColumnDefinition Widtha Grid，就像一DataGrid列：
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding ElementName=SampleDataGrid, Path=RowHeaderWidth}" />
<ColumnDefinition Width="{Binding ElementName=Column1, Path=ActualWidth}" />
<ColumnDefinition Width="{Binding ElementName=Column2, Path=ActualWidth}" />
</Grid.ColumnDefinitions>
Also, you need to define the same Stylefor the Gridheader and DataGrid.
此外，您需要Style为Grid标题和DataGrid.
