前两天有一个简单的C/S项目用到分页，因为是Winform下,没有现成的，自己也懒得写，就找了下，看到了ycmoon的一个控件
http://www.cnblogs.com/ycmoon/archive/2010/01/07/1640689.html
参考后，做了简化，只保留了分页的部分，主要是点击事件的Delegate，未做过多测试，有兴趣的朋友可以下载源码自行修改，如有好的建议，也可以给我反馈。3w@live.cn,效果如下：

附带一个取分页数据的存储过程：

在WinForm项目中，需要设置控件的总记录数RecordCount（由分页存储过程计算得出），和翻页事件winFormPager1_PageIndexChanged。
测试源码如下：

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
namespace DemoPager
{
public partial class frmMain : Form
{
public frmMain()
{
InitializeComponent();
}
#region Members
//总记录数
public int RecordCount = 0;
private string strConn = @"Data Source=ap2\vegnet;Initial Catalog=Db_TonyPaging;Integrated Security=SSPI;";
//"Server=localhost;database=Db_TonyPaging;uid=sa;pwd=sa;";
private string strProcedure = "ZJF_CPP_GetPagedRecordFor2005_2008";

//获取并设置总记录数
winFormPager1.RecordCount = RecordCount;
