How to: Create a Navigation Menu with TreeView Similar to One Used in Outlook 2003 Using SideBarView

SideBarView is a NavBarControl's view that was designed to simulate the Outlook 2003 navigation bar. SideBarView can display only one group at a time. To show custom content in a group instead of NavBarItems, set NavBarGroup.DisplaySource to "Content". To disable the built-in group scrolling so that controls can use their own scrolling mechanism, set the ScrollingSettings.ScrollMode attached property to "None".
