Devexpress xaf用代码打开菜单(Navigation Item)

第一种:ViewController继承WindowController

 public abstract class MyWindowController : WindowController
 {
        public MyWindowController()
        {
　　　　　　InitializeComponent();
        }
        protected override void OnActivated()
        {
            base.OnActivated();
            DevExpress.ExpressApp.SystemModule.ShowNavigationItemController svc =
             Frame.GetController<DevExpress.ExpressApp.SystemModule.ShowNavigationItemController>();
            SingleChoiceAction action = svc.ShowNavigationItemAction;
            ChoiceActionItem toSelect = action.FindItemByIdPath("菜单路径");
            if (toSelect == null)
            {
                XtraMessageBox.Show("未找到XX的菜单", GlobalConst.SystemTitle);
            }
            else
            {
                action.DoExecute(toSelect);
            }
        }
}

第二种方式:ViewController不继承WindowController

 public partial class MyViewController: ViewController
 {
        public MyViewController()
        {
　　　　　　InitializeComponent();
        }
        protected override void OnActivated()
        {
            base.OnActivated();
            DevExpress.ExpressApp.SystemModule.ShowNavigationItemController svc =
             Application.MainWindow.GetController<DevExpress.ExpressApp.SystemModule.ShowNavigationItemController>();
            SingleChoiceAction action = svc.ShowNavigationItemAction;
            ChoiceActionItem toSelect = action.FindItemByIdPath("菜单路径");
            if (toSelect == null)
            {
                XtraMessageBox.Show("未找到XX的菜单", GlobalConst.SystemTitle);
            }
            else
            {
                action.DoExecute(toSelect);
            }
        }
}

两者的区别就是一个通过Frame获取ShowNavigationItemController对象，另一个通过Application.MainWindow获取ShowNavigationItemController对象。
