Asp.Net實(shí)現(xiàn)的通用分頁(yè)函數(shù)

    本文實(shí)例講述了Asp.Net實(shí)現(xiàn)的通用分頁(yè)函數(shù)。分享給大家供大家參考，具體如下：
    功能：
    1.每頁(yè)設(shè)置顯示9頁(yè)，超過(guò)9頁(yè)，點(diǎn)5頁(yè)后的+1頁(yè)顯示（可以隨便修改）
    2.CSS樣式自己可以設(shè)置
    3.無(wú)任何咋代碼產(chǎn)生，利于搜索引擎優(yōu)化
    分頁(yè)程序
    objPDS = new PagedDataSource();
    objPDS.DataSource = dtTable.DefaultView;//綁定數(shù)據(jù)源
    objPDS.AllowPaging = true;
    objPDS.PageSize =10;//分頁(yè)數(shù)目
    int curPage;
    int cshi;
    int jshi;
    int zyes = Int32.Parse( objPDS.PageCount.ToString());
    this.tjixx.Text = "總共 <font color=red>" + dtTable.Rows.Count + " </font>條信息";
    this.tjixx.Text += "|共 <font color=red>" + zyes + " </font>頁(yè)";
    if (Request.QueryString["Page"] != null)
    {
      if (Int32.Parse(Request.QueryString["Page"]) > zyes)
        curPage = zyes;
      else
      curPage = Int32.Parse(Request.QueryString["Page"]);
    }
    else
    {
      curPage = 1;
    }
    if (zyes <= 9)
    {
      cshi = 1;
      jshi = zyes;
    }
    else
    {
      if (curPage <= 5)
      {
        cshi = 1;
        jshi = 9;
      }
    else
    {
      cshi = curPage - 4;
      int jshils = curPage + 4;
      if (jshils > zyes)
        jshi = zyes;
      else
        jshi=curPage + 4;
    }
    }
    objPDS.CurrentPageIndex = curPage - 1;
    StringBuilder m_strPageInfo = new StringBuilder();
    for (int i = cshi; i <=jshi; i++)
    {
      if (i == Int32.Parse(curPage.ToString()))
        m_strPageInfo.Append(" <span class=\"dqye\"> <strong>" + i + " </strong> </span> ");
      else
        m_strPageInfo.Append(" <span class=\"qtye\"> <strong> <a href=\"newslist_ej" + Request.QueryString["wzcat"] + "_Page" + i + ".html\">" + i + " </a> </strong> </span> ");
    }
    this.yemsl.Text = m_strPageInfo.ToString();
    if (!objPDS.IsFirstPage)
    {
      linkPre.NavigateUrl = "newslist_ej" + Request.QueryString["wzcat"] + "_Page" + Convert.ToString(curPage - 1);
      linkPre.NavigateUrl += ".html";
    }
    if (!objPDS.IsLastPage)
    {
      linkNext.NavigateUrl = "newslist_ej" + Request.QueryString["wzcat"] + "_Page" + Convert.ToString(curPage + 1);
      linkNext.NavigateUrl += ".html";
    }
    linkFirstPage.NavigateUrl = "newslist_ej" + Request.QueryString["wzcat"] + "_Page1";
    linkFirstPage.NavigateUrl += ".html";
    linkEndPage.NavigateUrl = "newslist_ej" + Request.QueryString["wzcat"] + "_Page" + objPDS.PageCount.ToString();
    linkEndPage.NavigateUrl += ".html";
    this.DataList4.DataSource = objPDS;//綁定分頁(yè)的數(shù)據(jù)
    this.DataList4.DataBind();
    Aspx文件：
    分頁(yè)部分：
    <div> <asp:HyperLink ID="linkFirstPage" runat="server" Font-Underline="False">首頁(yè) </asp:HyperLink><<
    <asp:HyperLink ID="linkPre" runat="server" Font-Underline="False">上一頁(yè) </asp:HyperLink>
    <asp:Literal ID="yemsl" runat="server"> </asp:Literal>
    <asp:HyperLink ID="linkNext" runat="server" Font-Underline="False">下一頁(yè) </asp:HyperLink>   
      >> <asp:HyperLink
      ID="linkEndPage" runat="server" Font-Underline="False">尾頁(yè) </asp:HyperLink>| <asp:Literal
        ID="tjixx" runat="server"> </asp:Literal> </div>
    希望本文所述對(duì)大家asp.net程序設(shè)計(jì)有所幫助。
