Infragistics WinTree

Databound and multi-column tree-based data navigation. Infragistics WinTree is a fully databound .NET tree view control for Windows Forms that supports single and multi-column nodes. Using the tree, you can easily display nested, hierarchical data that is based on ADO.NET data relationships. The benefit of employing a tree over a grid is its ability to have different column sets on each parent node allowing it to show highly heterogeneous data; where conversely a grid must limit itself to having the same column structure (homogeneous data) at each level. Trees also support many usage scenarios where users must navigate or explore naturally nested information such as folder-based file systems, music collections or parts catalogs.
