在WPF网格/列表中跨越多列的最佳方法？

Question

I have a custom user control I wrote in WPF to display some data. I want to show this usercontrol in a list, but I also want to provide multiple column headers (matching some properties on the user cotrol) so users can sort on properties contained in the usercontrol.

I am not sure the best way to go about this.

I currently have a ListBox displaying these user controls, but the ListBox has no header and I can't figure out how to put multiple headers on the ListBox.

Ideally I'd like something like this:

Header1   Header2  Header3   Header4
[UserControlThatSpansAllFourColumns]

My other thought was to use a DataGrid and somehow get each item to span multiple columns, but so far I can't figure that out either.

If anyone has any tips, I'd welcome them!

Ok, this is not in any case the "best way" but I'd just throw this in. One way that sort of works like what you need is to use a ListView with a custom ItemContainerStyle that uses a <ContentPresenter> instead of the default <GridViewRowPresenter> . This short XAML somewhat demonstrates this:

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListViewItem">
                        <ContentPresenter/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Header1"/>
            <GridViewColumn Header="Header2"/>
        </GridView>
    </ListView.View>

    <Button>Item1</Button>
    <Button>Item2</Button>

</ListView>

Here, you get the column headers, and the items span across the entire listview. In this solution, however, the rendering of items are kind of in a world of its own. It isn't really connected to the columns defined for the ListView. So I guess one way of making this work better is to provide your own <RowPresenter> implementation that actually takes into consideration the GridViewColumns defined in the parent listview.

Anyway, hope this helps somehow.
