<asp:datalist id="datalist1" runat="server">
..................
..................
..................
</asp:datalist><asp:HyperLink ID="lnPrevPage" runat="server">上一篇</asp:HyperLink>
<asp:HyperLink ID="lnNextPage" runat="server">下一篇</asp:HyperLink>
public PagedDataSource objpds;            conn.Open();
            SqlDataAdapter da = new SqlDataAdapter("......", conn);
            DataSet ds = new DataSet();
            da.Fill(ds, "...");
            conn.Close();            objpds = new PagedDataSource();
            objpds.DataSource = ds.Tables[0].DefaultView;
            objpds.AllowPaging = true;
            objpds.PageSize = 8;
            int curPage;
            if (Request.QueryString["Page"] != null)
            {
                curPage = Int32.Parse(Request.QueryString["Page"]);
            }
            else
            {
                curPage = 1;
            }            
          
                       if (!objpds.IsFirstPage)
            {
                lnPrevPage.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(curPage - 1);
                lnPrevPage.Enabled = true;
                lnPrevPage.ForeColor = System.Drawing.Color.CornflowerBlue;
            }
            else
            {
                lnPrevPage.Enabled = false;
            }
            if (!objpds.IsLastPage)
            {
                lnNextPage.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(curPage + 1);
                lnNextPage.Enabled = true;
                lnNextPage.ForeColor = System.Drawing.Color.CornflowerBlue;
            }
            else
            {
                lnNextPage.Enabled = false;
            }
             datalist1.DataSource = objpds;
            datalist1.DataBind();
