通过grdiview自定义分页或用aspnetpager,还可使用
  public string ShowPage(int PageCount, string Pageno,string  ClassID,string strColor)
        {
            string strL = "",strC="";;
            StringBuilder strB=new StringBuilder();
            if (Pageno != "")
            {
                if (int.Parse(Pageno) > PageCount)
                {
                    Pageno = "1";
                }
            }
            if (strColor.Trim().Length <= 0)
                strC = "#EEF8F9";
            else
                strC = strColor;
            string str = "";

                else
