What is meant by WinForms GroupBar and GroupView?

GroupBar and GroupView

The GroupBar and GroupView controls are part of the Essential Tools Navigation Package. The GroupBar implements a tab-type container that is capable of hosting a group of other controls. The GroupView control is a list-type interface that displays a collection of command items, where each command item is represented by an image and/or a text. The GroupBar and GroupView controls abide by the container-client model and are designed to work in perfect synchronization with each other. The controls can be used by themselves as stand-alone instances or in combination thus making it possible to implement popular interfaces such as the Microsoft Outlook 2003 Navigation bar, standard Outlook bar, Visual Studio.NET toolbox, Windows 2000/XP folder-list, MSN Taskbar list, XP Taskbar list etc., in Windows Forms applications.
