How to de-select a node in TreeView? De-selected node is still being displayed as SelectedNode. For example, there are three nodes in TreeView1: Node1, Node2 and Node3 and selectedNode is Node1. I can de-select Node1 by clicking another control on front panel. However, TreeView1.selectedNode.text is still "Node1" instead of a empty string. How do I "Update" node-selection status?
