DataList 能否分页，请问如何实现?

private void Page_Load(object sender, System.EventArgs e)
{
 PageSize=1;
 Conn= new SqlConnection(Application[“Guest_Conn”].ToString());
 Conn.Open();
 if(!Page.IsPostBack)
 {
  ListBind();
  CurrentPage = 0;
  ViewState[“PageIndex”] = 0;
  //计算总共有多少记录
  RecordCount = CalculateRecord();
  lblRecordCount.Text = RecordCount.ToString();
  //计算总共有多少页
  PageCount = RecordCount/PageSize;
  lblPageCount.Text = PageCount.ToString();
  ViewState[“PageCount”] = PageCount;
 }
}

//计算总共有多少条记录
public int CalculateRecord()
{
 int intCount;
 string strCount = “select count(*) as co from guest”;
 SqlCommand MyComm = new SqlCommand (strCount,Conn);
 SqlDataReader dr = MyComm.ExecuteReader();
 if(dr.Read())
 {
   intCount = Int32.Parse(dr[“co”].ToString());
 }
 else
 {
   intCount = 0;
 }
 dr.Close();
 return intCount;
}

ICollection CreateSource()
{
 int StartIndex;
 //设定导入的起终地址
 StartIndex = CurrentPage*PageSize;
 string strSel = “Select * from guest order by postdate desc”;
 DataSet ds = new DataSet();
 SqlDataAdapter MyAdapter = new SqlDataAdapter(strSel,Conn);
 MyAdapter.Fill(ds,StartIndex,PageSize,”guest”);
 return ds.Tables[“guest”].DefaultView;
}

public void ListBind()
{
 Myguest.DataSource = CreateSource();
 Myguest.DataBind();
 lbnNextPage.Enabled = true;
 lbnPrevPage.Enabled = true;
 if(CurrentPage==(PageCount-1)) lbnNextPage.Enabled = false;
 if(CurrentPage==0) lbnPrevPage.Enabled = false;
 lblCurrentPage.Text = (CurrentPage+1).ToString();
}

public void Page_OnClick(Object sender,CommandEventArgs e)
{
 CurrentPage = (int)ViewState[“PageIndex”];
 PageCount = (int)ViewState[“PageCount”];
 string cmd = e.CommandName;
 //判断cmd，以判定翻页方向
 switch(cmd)
 {
  case “next”:
   if(CurrentPage<(PageCount-1)) CurrentPage++;
   break;
  case “prev”:
   if(CurrentPage>0) CurrentPage–;
   break;
 }
 ViewState[“PageIndex”] = CurrentPage;
 ListBind();
}
