如何將控件放在WPF DataGrid頁眉的左側？

Question

我需要把一個菜單放在WPFDataGrid Header的左側，我不想把這個菜單放在ColumnHeaderStyle的每個列標題上，只有一次在左邊。這可能嗎？怎麼做？

好吧，謝謝混合！

<Style x:Key="DataGridStyle" TargetType="{x:Type DataGrid}"> 
    <Setter Property="Template" Value="{DynamicResource DataGridControlTemplate1}"/> 
</Style> 
<ControlTemplate x:Key="DataGridControlTemplate1" TargetType="{x:Type DataGrid}"> 
    <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True"> 
     <ScrollViewer x:Name="DG_ScrollViewer" Focusable="false"> 
      <ScrollViewer.Template> 
       <ControlTemplate TargetType="{x:Type ScrollViewer}"> 
        <Grid> 
         <Grid.ColumnDefinitions> 
          <ColumnDefinition Width="Auto"/> 
          <ColumnDefinition Width="*"/> 
          <ColumnDefinition Width="Auto"/> 
         </Grid.ColumnDefinitions> 
         <Grid.RowDefinitions> 
          <RowDefinition Height="Auto"/> 
          <RowDefinition Height="*"/> 
          <RowDefinition Height="Auto"/> 
         </Grid.RowDefinitions> 
         <"YourControls" Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.All}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" Grid.Column="1"> 
         <DataGridColumnHeadersPresenter x:Name="PART_ColumnHeadersPresenter" Grid.Column="1" Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.Column}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" d:IsLocked="True"/> 
         <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" Grid.ColumnSpan="2" Grid.Row="1" d:IsLocked="True"/> 
         <ScrollBar x:Name="PART_VerticalScrollBar" Grid.Column="2" Maximum="{TemplateBinding ScrollableHeight}" Orientation="Vertical" Grid.Row="1" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}" d:IsLocked="True"/> 
         <Grid Grid.Column="1" Grid.Row="2" d:IsLocked="True"> 
          <Grid.ColumnDefinitions> 
           <ColumnDefinition Width="{Binding NonFrozenColumnsViewportHorizontalOffset, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"/> 
           <ColumnDefinition Width="*"/> 
          </Grid.ColumnDefinitions> 
          <ScrollBar x:Name="PART_HorizontalScrollBar" Grid.Column="1" Maximum="{TemplateBinding ScrollableWidth}" Orientation="Horizontal" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportWidth}" d:IsLocked="True"/> 
         </Grid> 
        </Grid> 
       </ControlTemplate> 
      </ScrollViewer.Template> 
      <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> 
     </ScrollViewer> 
    </Border> 
</ControlTemplate> 

和

<DataGridStyle="{StaticResource DataGridStyle1}".../>
