如果您寻找的是这样的：
然后就可以使用ContainerStyle的GroupStyle的Template属性。在这个例子中，我使用一个DockPanel中，根据您所提供停靠在底部的网格和项目presenter填充剩余部分。此外，为了获得项目累计完成你必须使用一个转换器，它在底部提供。

I have a ListView that displays sales orders, and groups them by status. In WinForms I had a footer at the bottom of each group that displayed the Total sale price for each group, and I would like to do the same in WPF.
I have figured out how to group the orders, but I can't figure out how to create a footer.
This is my current group style:
<ListView.GroupStyle>
<GroupStyle HidesIfEmpty="True">
<GroupStyle.HeaderTemplate>
<DataTemplate>
<!--CollectionViewGroup.Name will be assigned the value of Status for that group.-->
<!--http://***.com/questions/639809/how-do-i-group-items-in-a-wpf-listview-->
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Path=Name}" HorizontalAlignment="Left" FontWeight="Bold" Foreground="Black"/>
<Line Grid.Column="1" Stroke="Black" X2="500" Fill="Black" VerticalAlignment="Center" />
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</ListView.GroupStyle>
If your looking for something like this:
Then you can use the Template property of the ContainerStyle for the GroupStyle. In this example I use a DockPanel, with the Grid you supplied Docked on the bottom and an ItemsPresenter filling the remainder. In addition in order to get the Items totaled you'd have to use a Converter, which is supplied at the bottom.
