这几天闲来无事,所以写了个大文章分页代码,下面提供给大家。
实现思路是:后台管理员文章发布的时候自己手动添加分页符,后台我用的也是 FCKeditor,所以修改了他的source增加了自己的button。在button的事件里写上自己的代码,当然就是直接insert innerhtml自己的分页标志了,我目前用的是|,|,|,|,|,|当然可以自定义其他的。首先提供个类库。

asp.net分页代码2 调用部分:
在aspx中增加label等元素。
- < asp:label id="currentpage" runat="server" CssClass="gray">当前页< /asp:label>
- < asp:label id="totalpage" runat="server" CssClass="gray">Label< /asp:label>
- < asp:hyperlink id="lnkfist" runat="server" CssClass="gray">首页< /asp:hyperlink>|
- < asp:hyperlink id="lnkprev" runat="server" CssClass="gray">前页< /asp:hyperlink>|
- < asp:hyperlink id="lnknext" runat="server" CssClass="gray">下页< /asp:hyperlink>|
- < asp:hyperlink id="lnklast" runat="server" CssClass="gray">尾页< /asp:hyperlink>
在aspx.cs中增加调用代码。
- private ContentPager pager;
- protected void Page_Load(object sender, EventArgs e)
- {
- int id = Convert.ToInt32(Request.QueryString["id"]);//接收参数,例如访问这个页是xxx.aspx?id=1
- DataSet ds = new DataSet();
- //从数据库读内容部分就略掉了
- DataRow drow;
- drow = ds.Tables[0].Rows[0];
- string cont = drow["content"].ToString();//此部分可以把内容中的HTML代码转换一下,我也省略了
- //文章分页,关键部分
- pager = new ContentPager();
- pager.Lnknext = this.lnknext;
- pager.Lnkprev = this.lnkprev;
- pager.Lnklast = this.lnklast;
- pager.Lnkfist = this.lnkfist;
- pager.Pagenum = this.currentpage;
- pager.Pagecount = this.totalpage;
- pager.DisplayContent = this.content;
- string query = "&id=" + Request.QueryString["id"].ToString();
- pager.datapager(cont, query);
- }
