      let position = 0 //Scroll to make a specified list item visible.
      listview.ScrollTo(item, position, true)
    }
    or
    function Test()
    {
      let listview = Mobile.Device()...XFObject("listView")
      for (let i = 0; i < listview.ItemsSource.Item(0).Count; i++)
      {
        let item = listview.ItemsSource.Item(0).Item(10)
        if (item.FullName == "Item 11")
          listview.ScrollTo(item, 0, true)
      }
    }
