        OleDbDataAdapter Comm = new OleDbDataAdapter(sql, conn);        DataSet ds = new DataSet();                           //DataSet 初试化
        Comm.Fill(ds, "Book");
        //使用PagedDataSource来实现分页

        {
            this.lbtnNextPage.Enabled = false;
            this.lbtnDownPage.Enabled = false;
        }
        GridView1.DataBind();//此处出现异常：索引 10 不是为负数，就是大于行数。点上下页控件出现
        conn.Close();                                  
    }

Answer 1

 pds.AllowPaging = true;将这个设为删除掉就行了

Answer 2

 在GridView1.DataBind();前面添加判断 
  if(ds.Tables.Rows.Count<=10)
{
   pds.AllowPaging = false;
}
