Occurs when a Single Choice Action’s item is changed by an end-user.
NuGet Package: DevExpress.ExpressApp
The SelectedItemChanged event's data class is EventArgs.
Handle this event, to execute custom code in response to manual changing of the current Single Choice Action’s SingleChoiceAction.SelectedItem property. If you need to respond to the SingleChoiceAction.SelectedItem property change performed by an end-user, handle the SingleChoiceAction.Execute event.
