Yes, I know, there already is a TreeListView control in the SDK, but it's simple and it isn't complete, so I developed a my custom control working on .NET Fx 3.0/3.5. It supports template, binding, scrolling and themes (classic, aero, luna). It's quite simple to use:

<r:TreeListView ItemsSource="{Binding Source={StaticResource data},XPath=/opml/body/outline/outline}" ItemTemplate="{StaticResource dt}">
    <r:TreeListView.Columns>
        <GridViewColumn Header="Title" DisplayMemberBinding="{Binding XPath=@title}" Width="150" />
        <GridViewColumn Header="Childs" DisplayMemberBinding="{Binding XPath=@count}" Width="100" />
        <GridViewColumn Header="Url" DisplayMemberBinding="{Binding XPath=@xmlUrl}" Width="200" />
    </r:TreeListView.Columns>
</r:TreeListView>

And below a screenshot of the control in action:

The control inherits from TreeView and TreeViewItem classes and uses a custom converter to indent items. The most of work is into the xaml files, built copying markup from original TreeView and ListView styles.
I used this control into my project PaperBoy.

I hope you find useful :-). Download full source control.
