网格扩展器标头 - 无法正确排列

Question

我Expander为a定义了以下内容DataGrid.

<Expander IsExpanded="True" HorizontalAlignment="Stretch" Background="Blue">
    <Expander.Header>
            <Grid HorizontalAlignment="Stretch" Background="BurlyWood">
                      <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="3*" />
                        <ColumnDefinition Width="*" />
                      </Grid.ColumnDefinitions>

                      <TextBlock Text="{Binding Path=Name, StringFormat=\{0:D\}}" FontWeight="Bold" />
                      <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Grid.Column="1">
                        <TextBlock Text="Total : "/>
                        <TextBlock Text="{Binding Path=Items, Converter={StaticResource sumConverter}}" FontWeight="Bold"/>
                      </StackPanel>
                </Grid>
        </Expander.Header>
        <ItemsPresenter />
</Expander>

我需要在左侧显示项目名称,在组头标题的右端显示总和.但是我得到的是:

如何将"总计"移动到标题的右端？

我有同样的问题,如果我记得正确的问题是,ContentPresenter对于Expander.Header不关心HorizontalAlignment的Expander.我找到了一个很好的解决方法:

<Expander.Header>
    <Grid HorizontalAlignment="{Binding Path=HorizontalAlignment, RelativeSource={RelativeSource AncestorType={x:Type ContentPresenter}}, Mode=OneWayToSource}">
        ...
    </Grid>
</Expander.Header>
