The XtraTreeList Suite is a comprehensive WinForms TreeView and ListView control by DevExpress.

From the DevExpress website:

The XtraTreeList Suite is a comprehensive WinForms TreeView and ListView control. It was built from the ground up in C# and is optimized to take full advantage of the .NET Framework. The XtraTreeList is a multi-purpose data visualization system that can display information as a TREE, a GRID, or a combination of both - in either data-bound or unbound mode. This unique synergy between a traditional grid and a traditional TreeView allows you to create cutting-edge and visually appealing application interfaces for your end-users.
