Showing connecting lines in TreeView

Description

 
Is there any plan to provide an option for showing connecting heirarchy lines in a TreeView like in a classical WindowsForm TreeView? Can this be accomplished somehow through modifying the TreeView/TreeViewItem control templates?

I definitely would want this feature in both WPF and Silverlight.

It's odd to get less functionality with a WPF control than with ASP.Net

This is an interesting issue because like pinidiya mentioned gridlines also aren't available in the WPF TreeView and we'd like Silverlight to be compatible with WPF. Also, most modern OS (Vista, Windows 7, OS X 10.5) have moved away from showing gridlines in TreeViews by default.

Your votes really do help drive features, so please keep voting and pushing these issues to let us know how strong the need is. Thank you.

Users expect this to be in WPF applications as well. Lack of this basic element could trigger negative feelings in end users. They question whether it's a failure in framework 2.0 to 3.5 migration process. They simply don't believe it.

Yes, this should defintely be added. The display of heirarchy lines has been standard since the inception of the treeview control. Users expect to see it. Certainly, developers should be able to style this and remove the behavior if their design requires it, but the ability to display the lines should be built in. A developer should not have to modify the control template to have this basic functionality.
