What is the WinForms XPTaskBar?
XPTaskBar
Windows XP introduced this new user interface component in its Control Panel, Windows Explorer, and other system applications. The Essential Suite XP Task Bar emulates this XP control. Essential Tools implements this control for use with Windows Forms applications. This control can be used to show a multi-category list of frequently used tasks in a panel docked to the left, for example.
