Visual Studio 2008: Setting the vertical separation to default in wpf designer

I favour the vertical separation over the horizontal separation in VS2008 wpf designer.

But after deleting the .suo (fresh checkout, new project, etc.) this setting is gone.

Is there a way to tell visual studio to default to the v开发者_如何学Certical separation instead of the horizontal for wpf designer ?

I can not find anything in the "options". Did I miss this setting?

Unlike in the HTML designer of Visual Studio (!) there is currently no way to make the vertical split the default in the XAML designer: see here. You will always have to set it manually on a per file basis. These settings will indeed be stored in the .suo file. Unfortunately this applies to both Visual Studio 2008 and 2010. You can file a request to remove this inconsitency in the next release here.
