GridView自带的分页功能实现：

要实现GrdView分页的功能

操作如下：

1、更改GrdView控件的AllowPaging属性为true。

2、更改GrdView控件的PageSize属性为 任意数值（默认为10）

3、更改GrdView控件的PageSetting->Mode为Numeric等（默认为Numeric）该属性为分页样式。

GridView属性设置好了，从页面上也能看到分页样式。

现在开始实现分页的功能：

1、在<<asp:GridView ID=......>后添加，OnPageIndexChanging="GridView1_PageIndexChanging"

2、在对应的aspx.cs中添加：

    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)

    {

        GridView1.PageIndex = e.NewPageIndex;

        InitPage(); //重新绑定GridView数据的函数

    }

参考代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="gridview_zidaifenye.aspx.cs" Inherits="gridview_zidaifenye" %>
             
     
    
      
     
                   
                        
                         
                         
                     
                
               每页显示
                   
        
         5
                    
        
         10
                    
        
         15
                
               条记录             
           
      
    
     

后台代码：

using System;using System.Collections.Generic;using System.Data;using System.Data.SqlClient;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class gridview_zidaifenye : System.Web.UI.Page{    DBAccess db = new DBAccess();    protected void Page_Load(object sender, EventArgs e)    {        if (!IsPostBack)        {            // gvProduct.DataSource = getData();            // gvProduct.DataBind();            BindGrid();        }    }    public void BindGrid()    {        SqlCommand comm = db.CreateCommand("select * from product p,Uuser u where p.userid=u.id");        SqlDataAdapter sda = new SqlDataAdapter();        sda.SelectCommand = comm;        DataSet ds = new DataSet();        sda.Fill(ds,"Datatable");        DataView dv = ds.Tables[0].DefaultView;        GridView1.DataSource = dv;        GridView1.DataBind();    }    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)    {        GridView1.PageSize = int.Parse(DropDownList1.SelectedValue);        GridView1.PageIndex = 0;        BindGrid(); //GridView1.DataBind();    }    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)    {        lblMsg.Text = "当前页为第" + (GridView1.PageIndex + 1).ToString() + "页，共" + (GridView1.PageCount).ToString() + "页";    }    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)    {        GridView1.PageIndex = ((GridViewPageEventArgs)e).NewPageIndex;        BindGrid(); //重新绑定GridView数据的函数    }}

   总结下，方便以后用到。
