Virtual Tree

Dedicated to software developers, Virtual Tree is a native .NET tree view control that faciliates advanced data binding features to ADO.NET DataSets, DataViews and any other class compatible with the IList interface.

Compared to other similar tools, this one is specially designed to be data drivn. Others allow users to manually put together the tree nodes and then automatically create the in-memory tree in accordance with the Data Source, which means that the whole tree has to be built before showing it when it comes to Data Sources containing numerous nodes (on any level), resulting in a resource-demanding and slow process.

These inconveniences can be avoided with Virtual Tree since only the data necessary (first 30 or so items) for showing the current tree status is extracted from the Data Source, regardless of its size. The developer can set a different RowBinding for each type of item in the tree, which means that complex relationships and various data found in the real world can be displayed.

ContextSensitive columns can be used too. They can be shown or hidden dynamically and are bound to the data type in the currently selected Row (ideal for viewing heterogenous data). In general, the columns can be customized and sorted in any way, automatically resized, and pinned.

Virtual Tree has drag-and-drop along with multi- and drag-selection support, and it is compatible with Microsoft Active Accessibility (MSAA). Sample projects are included in the installed package, together with comprehensive documentation.
