上面是aspx代码

下面是对应的cs代码

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using DAL;

public partial class Default3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            //执行sql语句获得数据总数A
            string sql = "select count(*) from testst";
            int A = (int)SqlHelper.ExecuteScalar(sql);
            AspNetPager1.RecordCount = A;
            bindData();//执行绑定数据
        }
    }

    void bindData()
    {
        //StartRecordIndex 当前数据记录的起始索引
        //EndRecordIndex  当前页最后一条记录的索引
        //
        //NumericButtonCount = "4"  
        int PageSize = AspNetPager1.PageSize;
        int NOPageSize = PageSize * (AspNetPager1.CurrentPageIndex - 1);
        string sql = "select top "+PageSize+" * from testst where sno not in(select top "+NOPageSize +" sno from testst )";
        DataTable dt = SqlHelper.ExecuteDatatable(sql);
        rpt1.DataSource = dt;
        rpt1.DataBind();
    }
    protected void AspNetPager1_PageChanged(object src, EventArgs e)
    {
        bindData(); //连续点击 反映速度太慢  不知道为啥
    }





}

使用需要sqlhelp 类库对应的命名空间 using DAL;

看了好多大神的代码好复杂自己结合repeater控件的学习研究了一翻

AlwayShow=true 总显示分页控件

CurrentPageIndex =1 当前页的索引

FirstPageText = 首页第一页按钮上显示的文本

LastPageText = 末页最后一页按钮上显示的文本

PrevPageText =上一页上一页按钮上显示的文本

NextPageText =下一页下一页按钮上显示的文本

PageChanged = AspNetPager1_PageChanged

页面已更改事件

NumericButtonCount = 4 要显示的页索引值的按钮的数目

PageSize =5 每页显示的记录数

CustomInfoHTML 要显示在用户自定义信息区的[用户自定义HTML信息文本]
