The TreeViewControl uses an in-place editor that depends on its content.
Use the EditSettings property to manually define an editor.
Handle the ValidateNode event to validate new node values.
Use the ShowingEditor event to prevent the activation of a node’s editor.
In unbound mode, users cannot edit nodes of simple types (string, integer, etc.). To allow users to edit an unbound tree, set an object as the node’s content.
