Datapager to change visible listview page automatically when next page is availa

I could not find anything on the site you gave me above, but have since found the answer on another website and the code is as follows:-

// This code will automatically display next listview page when adding records
        DataPager Pager1 = ListView1.FindControl("Pager1") as DataPager;
        int lastpage = Pager1.TotalRowCount / Pager1.PageSize;
        if (Pager1.TotalRowCount % Pager1.PageSize == 0)
        {
            lastpage++;
        }

        Pager1.SetPageProperties((lastpage) * Pager1.PageSize, Pager1.MaximumRows, false);

        ListView1.DataBind();
