学习：WinForm分页控件（转）
分页用户控件，使用效果如上图，可以用在查询窗体，代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
namespace Kimbanx.SecurityDiskSystem.Controls
{
public partial class SelectPaging : UserControl
{/**//// <summary>
/// 每页显示记录数
/// </summary>
private int _pageSize = 20;
/**//// <summary>
/// 每页显示记录数
/// </summary>
public int PageSize
{
get { return _pageSize; }
set { _pageSize = value; }
}/**//// <summary>
/// 总记录数
/// </summary>
private int _nMax = 0;
/**//// <summary>
/// 总记录数
/// </summary>
public int NMax
{
get { return _nMax; }
set { _nMax = value; }
}/**//// <summary>
/// 页数=总记录数/每页显示记录数
/// </summary>
private int _pageCount = 0;
/**//// <summary>
/// 页数=总记录数/每页显示记录数
/// </summary>
public int PageCount
{
get { return _pageCount; }
set { _pageCount = value; }
}/**//// <summary>
/// 当前页号
/// </summary>
private int _pageCurrent = 0;
/**//// <summary>
/// 当前页号
/// </summary>
public int PageCurrent
{
get { return _pageCurrent; }
set { _pageCurrent = value; }
}/**//// <summary>
/// 当前记录行
/// </summary>
private int _nCurrent = 0;
/**//// <summary>
/// 当前记录行
/// </summary>
public int NCurrent
{
get { return _nCurrent; }
set { _nCurrent = value; }
}
/**//// <summary>
/// 设置数据源
/// </summary>
private DataTable dataSource = null;
/**//// <summary>

public DataTable DataSource
{
get { return dataSource; }
set { dataSource = value; }
}
//private DataSet ds = null;
public void InitDataSet(DataTable dt)
{
this.dataSource = dt;
this._nMax = this.dataSource.Rows.Count;
//计算总页数
this._pageCount = _nMax / _pageSize;
//
if ((_nMax % _pageSize) > 0)
_pageCount++;
_pageCurrent = 1;
_nCurrent = 0;
FillData();
}
/**//// <summary>
/// 默认构造函数
/// </summary>
public SelectPaging()
{
InitializeComponent();
lblMsg.Enabled = false;
}
/**//// <summary>
/// 填充数据
/// </summary>
private void FillData()
{
//当前页面开始记录行
int nStartPos = 0;
//当前页面结束记录行
int nEndPos = 0;
DataTable dtTemp = this.dataSource.Clone();
if (this._pageCurrent == this._pageCount)
nEndPos = _nMax;
else
nEndPos = this._pageCurrent * this._pageSize;
nStartPos = this._nCurrent;
lblMaxPage.Text = this._pageCount.ToString();
txtCurrentPage.Text = this._pageCurrent.ToString();
for (int i = nStartPos; i < nEndPos; i++)
{
dtTemp.ImportRow(this.dataSource.Rows[i]);
_nCurrent++;
}
bdSource.DataSource = dtTemp;
bdNav.BindingSource = bdSource;
dataGV.DataSource = bdSource;
}
private void bdNav_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
switch (e.ClickedItem.Text)
{
case "移到上一条记录":
//FillData();
break;
case "移到下一条记录":
//FillData();
break;
case "上一页":
if (this._pageCurrent == 1)
{
lblMsg.Text = "已经是第一页，请点击“下一页”查看！";
//btnPrePage.Enabled = false;
return;
}
else
{
_pageCurrent--;
this._nCurrent = this._pageSize * (_pageCurrent - 1);
FillData();
}
break;
case "下一页":
if (this._pageCurrent == _pageCount)
{
lblMsg.Text = "已经是最后一页，请点击“上一页”查看！";
return;
}
else
{
_pageCurrent++;
this._nCurrent = this._pageSize * (_pageCurrent - 1); FillData();
}
break;
}
}
}
}
dataGV是网格控件datagridview控件
bdsource是绑定源控件bandingsource
