Remarks

Each time the treelist's selection is changed, the SelectionChanged event is raised. The event parameter's GridSelectionChangedEventArgs.Action property indicates how the selection has been changed. The TreeListSelectionChangedEventArgs.Node property returns the node whose selected state has been changed.

The SelectionChanged event is not fired if the DataControlBase.SelectionMode is set to TableViewSelectMode.None.
