Vista - vertical GridView

Hi all,

I'd like to get a kind of vertical GridView (like described in this
post : http://forums.microsoft.com/MSDN/Sho...48821&SiteID=1).

But i'd like a "cleaner" solution than using rotate transforms.

I can see two ways for achieving that
1) templating of the existing GridView.
But as it seems GridViewRowPresenter and GridViewHeaderRowPresenter
are not stylable, i'm stucked on this way.

2) creating my own View.
But i'm annoyed with some concerns as dynamically create grids for
sharing the height of the data rows and hearder row (with
ShareSizeGroup).

Ideas just to avoid wrong directions ?
