ASPxTreeList is a feature-complete treeview-grid control for Visual Studio. ASPxTreeList 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 synergy between a traditional grid and a traditional treeview allows you to create cutting-edge and visually appealing web application interfaces for your end-users with ease. ASPxTreeList fully exploits existing DevExpress appearance and data management technologies for ASP.NET. ASPxTreeList includes features such as on-demand loading of individual nodes and callback support ensure that the solutions you build are both elegant and effective. In the implementation, the control never needs to transmit the entire tree structure when being updated. ASPxTreeList is smart enough to determine which portion of the tree to be renewed and only requests a few records from the server, making user interaction extremely fast.
