Remarks
The FocusedNodeChanged event fires when focus moves from node to node for the following reasons:
- A user moves focus to a node.
- The TreeList.FocusedNode property is changed in code.
- Focus moves to the added node when you use the TreeList.AppendNode method.
- Focus moves to the focused node’s parent after the parent node is collapsed.
- The focused node is removed from the Tree List control.
Handle the TreeList.BeforeFocusNode event to specify whether a particular node can receive focus.
You can use the FocusedRowChanged and TreeList.SelectionChanged events interchangeably in single selection mode (see treeList.OptionsSelection.MultiSelect).
