thanks for many responses! i find solution:

 bool Scrolling = true;
        private void listBoxAdv1_Scroll(object sender, ScrollEventArgs e)
        {
            if (Scrolling == true)
            {
                Scrolling = false;
                listBoxAdv2.BeginUpdate();
                listBoxAdv2.AutoScrollPosition = new Point(listBoxAdv1.AutoScrollPosition.X, listBoxAdv1.AutoScrollPosition.Y);
                listBoxAdv2_Scroll(sender, e);
                listBoxAdv2.EndUpdate();
                Scrolling = true;
            }
        }

        private void listBoxAdv2_Scroll(object sender, ScrollEventArgs e)
        {
            if (Scrolling == true)
            {
                Scrolling = false;
                listBoxAdv1.BeginUpdate();
                listBoxAdv1.AutoScrollPosition = new Point(listBoxAdv2.AutoScrollPosition.X, listBoxAdv2.AutoScrollPosition.Y);
                listBoxAdv1_Scroll(sender, e);
                listBoxAdv1.EndUpdate();
                Scrolling = true;
            }
