I\'m a bit beginner in WPF, so I ask this..
Let\'s say I have a window, and inside the window I want to have something like container, could be just border or maybe
What you are describing sounds pretty close to a standard TabControl, but with a ControlTemplate that puts the tabs on the left side instead of above the content panel. Using this method would mean having a UserControl in each TabItem, eg. multiple controls. You can find out more about the TabControl from the TabControl Class page at MSDN.
