Asp.Net实现的通用分页函数

本文实例讲述了asp.net实现的通用分页函数。分享给大家供大家参考，具体如下：

功能：

1.每页设置显示9页，超过9页，点5页后的+1页显示（可以随便修改）
2.css样式自己可以设置
3.无任何咋代码产生，利于搜索引擎优化

分页程序

objpds = new pageddatasource();
objpds.datasource = dttable.defaultview;//绑定数据源
objpds.allowpaging = true;
objpds.pagesize =10;//分页数目
int curpage;
int cshi;
int jshi;
int zyes = int32.parse( objpds.pagecount.tostring());
this.tjixx.text = "总共 <font color=red>" + dttable.rows.count + " </font>条信息";
this.tjixx.text += "|共 <font color=red>" + zyes + " </font>页";
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;//绑定分页的数据
this.datalist4.databind();

aspx文件：

分页部分：

<div align="center"> <asp:hyperlink id="linkfirstpage" runat="server" font-underline="false">首页 </asp:hyperlink><<
<asp:hyperlink id="linkpre" runat="server" font-underline="false">上一页 </asp:hyperlink>
<asp:literal id="yemsl" runat="server"> </asp:literal>
<asp:hyperlink id="linknext" runat="server" font-underline="false">下一页 </asp:hyperlink>   
  >> <asp:hyperlink
  id="linkendpage" runat="server" font-underline="false">尾页 </asp:hyperlink>| <asp:literal
    id="tjixx" runat="server"> </asp:literal> </div>
