Event Data

The SelectionChanged event's handler receives an argument of the TreeListSelectionChangedEventArgs type. The following properties provide information specific to this event:

Property	Description
Action	Gets an action which indicates how the grid's selection has been changed. Inherited from GridSelectionChangedEventArgs.
ControllerRow	Identifies the row whose selected state has been changed. Inherited from GridSelectionChangedEventArgs.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
Node	Gets a node whose selected state has been changed.

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 TreeListView.MultiSelectMode is set to TableViewSelectMode.None.
