    {
        UpdatePageInfo();
    }
}

private void UpdatePageInfo()
{
    int totalRows = gridView.Rows.Count;
    int pageSize = gridView.PageSize;
    int currentPage = gridView.PageIndex + 1;
    int totalPages = (int)Math.Ceiling((double)totalRows / pageSize);

    lblPageInfo.Text = string.Format("总页数：{0}，总行数：{1}", totalPages, totalRows);
}

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
