说是分页控件，其实只显示了页码显示和分页导航功能，具体的数据分页还需要另外写代码实现，因为具体应用中数据分页的实现方法比较多，也比较灵活，所以觉得不包含进来的好，后面我会给出我使用的分页存储过程以及该存储过程和这个分页控件结合起来使用的方法。

源代码如下：

using System;
using System.Collections.Specialized;
using System.Drawing;
using System.IO;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace Eadd.Controls.WebControls
{
/// <summary>
/// 分页控件
/// </summary>
[DefaultProperty("Text"),
ToolboxData("<{0}:PageIndex runat=server></{0}:PageIndex>")]
public class PageIndex : System.Web.UI.WebControls.WebControl
{
  private int _current_page;
  private int _max_page;
  private string _url;
  private string _page_arg_name;
  private string _other_query_string;
  private Color _forecolor2;

  public PageIndex()
   {
   this.CurrentPage = 1;
   this.MaxPage = 1;
   this.PageArgName = "page";
   this.ForeColor = Color.White;
   this.ForeColor2 = Color.Gray;
   this.URL = "";
   this.OtherQueryString = "";

   this.Init += new EventHandler(PageIndex_Init);
   }

  private string PagerID
   {
   get
    {
    return this.ID + "_pager";
    }
   }

  private void PageIndex_Init(object sender, System.EventArgs e)
   {
   this.CurrentPage = 1;

    HttpRequest request = this.Page.Request;

   this.URL = Path.GetFileName(request.Path);
   
   string[] keys = request.QueryString.AllKeys;
   foreach(string key in keys)
    {
    if(key == this.PageArgName)
     this.CurrentPage = Convert.ToInt32(request[key]);
     else
     this.OtherQueryString += "&" + key + "=" + request[key];
    }

   string script = "";

    script += "<script language='JavaScript'>\r\n";
    script += "function eaddpageindexgoto()\r\n";
    script += "{\r\n";
    script += "var p = document.getElementById('" + PagerID + "')\r\n";
    script += "if(p.value != '')\r\n";
    script += "{\r\n";
    script += "self.location.href='" + this.URL + "?" + this.PageArgName + "=' + p.value + '" + this.OtherQueryString + "'\r\n";
    script += "}\r\n";   
    script += "}\r\n";
    script += "</script>\r\n";

    this.Page.RegisterClientScriptBlock("PageIndexScript", script);
   }

    }
   set

    }
   }

  private string OtherQueryString
   {

    {
    return _other_query_string;
    }
   set
    {
     _other_query_string = value;
    }
   }

  public int CurrentPage
   {
   get
    {

    }
   set

   }
