Silverlight Outlook Bar
Control that matches the presentation of Outlook 2007/2010 navigation bar.
Users can at any time collapse the xamOutlookBar so that it retracts to a vertical bar, yielding maximum space to your application.
When groups exceed the space available to them in the Outlook group bar, the UI can compress to a small icon.
Users can govern how much space the xamOutlookBar's selected group content receives by using the group area splitter bar dividing the selected group content from the groups presenter.
