You can change the orientation of the RadTabStrip by two steps:
- removing CSS classes for the horizontal orientation: RadTabStrip and RadTabStripTop_[Skin] or RadTabStripBottom_[Skin]
- adding CSS classes for the vertical orientation: RadTabStripVertical and RadTabStripLeft_[Skin] or RadTabStripRIght_[Skin]. Please, find a sample project in the attachment.
