Remarks

The TreeList displays data in a hierarchical structure using nodes (TreeListNode objects). The hierarchical level of a certain TreeListNode can be obtained with the TreeListNode.Level property. Nodes can be expanded to display nested nodes. To expand a particular node, set the TreeListNode.Expanded property to true.

The ExpandToLevel method expands nodes up to the specified level. For instance, calling the ExpandToLevel method with the level parameter set to 0, expands all root nodes.
