使用MVVM显示视图的正确方法

I am brand new to both wpf and MVVM. I have a Mainwindow that has two views left side has a usercontrol with a listbox and the list box has a edit button inside of it. On the right I have another view that contains all my controls for viewing and editing the record. I can select an item in the list box and edit my record since using binding it automatically populates by the selectedItem object. What I want to do is when the user hits the edit button show the view on the right if they hit another button contained in the list box then show that view on the right and close the previous view. I think I am missing a big concept here since most of the examples are to simplistic and just show one view. I really dont want to have to do it in the code behind. I have looked at John smiths tab and would like to do something similur without the tabs though. Any help would be greatly appreciated.I am brand new to both wpf and MVVM. I have a M
