    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]
