SelectedNodes Property

Gets a collection of UltraTreeNode objects that are currently selected in the UltraTree control.
Public ReadOnly Property SelectedNodes As SelectedNodesCollection
public SelectedNodesCollection SelectedNodes {get;}

This collection contains references to all selected nodes in the UltraTree. Adding a Node to this collection will select the node. Removing a node from this collection will deselect the node.

Any time a node is selected/deselected, either by user action or in code, it is automatically added/removed from the SelectedNodes collection.

The following sample code illustrates some of the information available in the SelectionDragStart event.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
