更改datagrid wpf中每个组的头

奇怪的是,没有人回答这个问题,对@Archie来说可能已经太晚了,或者更可能他早就找到了答案。但不管怎样,还是这样:

<GroupStyle.ContainerStyle>
    <Style TargetType="{x:Type GroupItem}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type GroupItem}">
                    <Expander Loaded="GroupHeaderExpander_Loaded">
                        <Expander.Header>
                            <StackPanel Orientation="Horizontal">
                                <TextBlock Text="Author: "/>
                                <TextBlock Text="{Binding Path=Name}"/>
                                <TextBlock Text=" "/>
                                <TextBlock Text="{Binding Path=ItemCount}"
                                           FontStyle="Italic"/>
                                <TextBlock Text=" Books" FontStyle="Italic"/>
                            </StackPanel>
                        </Expander.Header>
                        <ItemsPresenter>

                        </ItemsPresenter>
                    </Expander>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</GroupStyle.ContainerStyle>
