asp.net repeater手写分页实例代码

复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using BLL;
using Model;
using System.Data.SqlClient;
using System.Data;
public partial class Test_RepeaterFENYE : System.Web.UI.Page
{
private readonly static CategoryBLL cb = new CategoryBLL();
private readonly static Category_Info cgi = new Category_Info();
int Menu_ID = 0;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}
private void BindData()
{
IList li = cb.GetAllCategory();
if (li.Count > 0)
{
PagedDataSource pds = new PagedDataSource();
pds.DataSource = li;
pds.AllowPaging = true;
pds.PageSize =2;
int curPage;
if (Request.QueryString["page"] != null)
{
curPage = Convert.ToInt32(Request.QueryString["page"]);
}
else
{
curPage = 1;
}
pds.CurrentPageIndex = curPage - 1;
this.Repeater1.DataSource = pds;
this.Repeater1.DataBind();
this.Label4.Text = "";
this.Label4.Text += "共有" + li.Count.ToString() + "条记录 ";
this.Label4.Text += "每页显示" + pds.PageSize + "条 ";
this.Label4.Text += "共" + pds.PageCount.ToString() + "页 ";
this.Label4.Text += "当前第" + curPage.ToString() + "页  ";
if (curPage == 1)
{
this.Label4.Text += "首页 ";
this.Label4.Text += "上一页 ";
}
else
{
//this.Label4.Text += "首页 ";
//this.Label4.Text += "上一页  ";
this.Label4.Text += "首页 ";
this.Label4.Text += "上一页  ";
}
if (curPage == pds.PageCount)
{
this.Label4.Text += "下一页 ";
this.Label4.Text += "尾页 ";
}
else
{
this.Label4.Text += "下一页  ";
this.Label4.Text += "尾页  ";
//this.Label4.Text += "下一页 ";
//this.Label4.Text += "尾页 ";
}
string HtmlSelectString = "";
for (int i = 1; i <= pds.PageCount; i++)
{
if (i == curPage)
{
//HtmlSelectString += "第" + i + "页";
HtmlSelectString += "第" + i + "页";
}
else
{
//HtmlSelectString += "第" + i + "页";
HtmlSelectString += "第" + i + "页";
}
}
HtmlSelectString += "";
this.Label4.Text += "" + HtmlSelectString + "";
}
else
{
Label4.Text = "没有数据!";
}
}
}
注：//注释部分为url rewrite的效果。。。li返回的值为SQL查询后所得到表中所有的记录。。。
