InfoPath代码切换视图

Load时候切换视图

 XPathNavigator Navigator = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field1", NamespaceManager);
            string value1 = Navigator.Value;
            if (string.IsNullOrEmpty(value1))
            {
                e.SetDefaultView("View2");
            }
            else if (value1 == "1")
            {
                e.SetDefaultView("View4");
            }

            else
            {
                e.SetDefaultView("View3");

            }

按钮或事件切换视图

 public void CTRL2_5_Clicked(object sender, ClickedEventArgs e)
        {
            // Write your code here.
            this.ViewInfos.SwitchView("View4");
        }
