Occurs when a minimized NavBarGroup within a Navigation Pane View is expanded.
The NavPaneMinimizedGroupFormShowing event's data class is DevExpress.XtraNavBar.NavPaneMinimizedGroupFormShowingEventArgs.
The NavPaneMinimizedGroupFormShowing event occurs before a minimized NavBarGroup expands and displays its NavBarItems in a pop-up form (see the figure below). This NavBarGroup behavior is implemented in the Navigation Pane View only. See the Views topic to learn more.
