Occurs after grid's selection has been changed.
public event GridSelectionChangedEventHandler SelectionChanged
Public Event SelectionChanged As GridSelectionChangedEventHandler
The SelectionChanged event handler receives an argument of the DevExpress.UI.Xaml.Grid.GridSelectionChangedEventArgs type.
Each time the grid's selection is changed, the SelectionChanged event is raised. The event parameter's 'Action' property indicates how the grid's selection has been changed.
The SelectionChanged event isn't fired if the DataControlBase.SelectionMode property is set to MultiSelectMode.None.
