Synchronized ListView objects (or how to scroll 2 ListView objects together)

In my previous post I have described how to synchronize two ListBox objects. Here I will show, how to synchronize two ListView objects.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace SyncLists
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.listView1.View = View.Details;
            this.listView2.View = View.Details;
            for (int j = 0; j < 10; j++)
            {
                this.listView1.Columns.Add("c" + j.ToString());
                this.listView2.Columns.Add("c" + j.ToString());
            }
            for (int j = 0; j < 300; j++)
            {
                ListViewItem item = new ListViewItem("item" + j.ToString());
                for (int k = 1; k < 10; k++)
                {
                    item.SubItems.Add("sub item" + k.ToString());
                }
                this.listView1.Items.Add(item);
                this.listView2.Items.Add(item.Clone() as ListViewItem);
            }

            this.listView1.Scroll += new ListViewEx.ScrollHandler(listView1_Scroll);
        }
