准备工作

当一个列表加载数据过多时，比如datagridview，如果数据过多，则可能超出内存，相应慢等问题，此时需要用到翻页控件。

设计思路，对翻页控件定义接口，基类实现，如果所列的翻页控件样式或功能无法满足你的需求的话，你只需要基类翻页控件基类或者实现接口即可。

定义接口是因为后面的一些列表控件内置了翻页控件，为了达到兼容扩展，所有使用了接口定义约束。

开始

首先需要一个分页事件用到的委托，偷懒，只写了一个

[Serializable]
    [ComVisible(true)]
    public delegate void PageControlEventHandler(object currentSource);

我们先定义一个接口IPageControl

  public interface IPageControl
     {
         /// <summary>
         /// 数据源改变时发生
         /// </summary>
         event PageControlEventHandler ShowSourceChanged;
         /// <summary>
         /// 数据源
         /// </summary>
         List<object> DataSource { get; set; }
         /// <summary>
         /// 显示数量
         /// </summary>
         int PageSize { get; set; }
         /// <summary>
         /// 开始下标
         /// </summary>
         int StartIndex { get; set; }
         /// <summary>
         /// 第一页
         /// </summary>
         void FirstPage();
         /// <summary>
         /// 前一页
         /// </summary>
         void PreviousPage();
         /// <summary>
         /// 下一页
         /// </summary>
         void NextPage();
         /// <summary>
         /// 最后一页
         /// </summary>
         void EndPage();
         /// <summary>
         /// 重新加载
         /// </summary>
         void Reload();
         /// <summary>
         /// 获取当前页数据
         /// </summary>
         /// <returns></returns>
         List<object> GetCurrentSource();
         /// <summary>
         /// 总页数
         /// </summary>
         int PageCount { get; set; }
         /// <summary>
         /// 当前页
         /// </summary>
         int PageIndex { get; set; }
     }

然后定义一个分页基类控件，添加一个用户控件，命名UCPagerControlBase，并实现接口IPageControl

看下属性

 /// <summary>
         /// 总页数
         /// </summary>
         public virtual int PageCount
         {
             get;
             set;
         }
         private int m_pageIndex = ;
         /// <summary>
         /// 当前页码
         /// </summary>
         public virtual int PageIndex
         {
             get { return m_pageIndex; }
             set { m_pageIndex = value; }
         }
         /// <summary>
         /// 关联的数据源
         /// </summary>
         public virtual List<object> DataSource { get; set; }
         public virtual event PageControlEventHandler ShowSourceChanged;
         private int m_pageSize = ;
         /// <summary>
         /// 每页显示数量
         /// </summary>
         [Description("每页显示数量"), Category("自定义")]
         public virtual int PageSize
         {
             get { return m_pageSize; }
             set { m_pageSize = value; }
         }
         private int startIndex = ;
         /// <summary>
         /// 开始的下标
         /// </summary>
         [Description("开始的下标"), Category("自定义")]
         public virtual int StartIndex
         {
             get { return startIndex; }
             set
             {
                 startIndex = value;
                 if (startIndex <= )
                     startIndex = ;
             }
         }

然后定义虚函数，并做一些默认实现

/// <summary>
        /// 第一页
        /// </summary>
        public virtual void FirstPage()
        {
            if (DataSource == null)
                return;
            startIndex = ;
            var s = GetCurrentSource();

            if (ShowSourceChanged != null)
            {
                ShowSourceChanged(s);
            }
        }
        /// <summary>
        /// 上一页
        /// </summary>
        public virtual void PreviousPage()
        {
            if (DataSource == null)
                return;
            if (startIndex == )
                return;
            startIndex -= m_pageSize;
            if (startIndex < )
                startIndex = ;
            var s = GetCurrentSource();

            if (ShowSourceChanged != null)
            {
                ShowSourceChanged(s);
            }
        }
        /// <summary>
        /// 下一页
        /// </summary>
        public virtual void NextPage()
        {
            if (DataSource == null)
                return;
            if (startIndex + m_pageSize >= DataSource.Count)
            {
                return;
            }
            startIndex += m_pageSize;
            if (startIndex < )
                startIndex = ;
            var s = GetCurrentSource();

            if (ShowSourceChanged != null)
            {
                ShowSourceChanged(s);
            }
        }
        /// <summary>
        /// 最后一页
        /// </summary>
        public virtual void EndPage()
        {
            if (DataSource == null)
                return;
            startIndex = DataSource.Count - m_pageSize;
            if (startIndex < )
                startIndex = ;
            var s = GetCurrentSource();

            if (ShowSourceChanged != null)
            {
                ShowSourceChanged(s);
            }
        }
        /// <summary>
        /// 刷新数据
        /// </summary>
        public virtual void Reload()
        {
            var s = GetCurrentSource();
            if (ShowSourceChanged != null)
            {
                ShowSourceChanged(s);
            }
        }
        /// <summary>
        /// 获取当前页数据
        /// </summary>
        /// <returns></returns>
        public virtual List<object> GetCurrentSource()
        {
            if (DataSource == null)
                return null;
            int intShowCount = m_pageSize;
            if (intShowCount + startIndex > DataSource.Count)
                intShowCount = DataSource.Count - startIndex;
            object[] objs = new object[intShowCount];
            DataSource.CopyTo(startIndex, objs, , intShowCount);
            var lst = objs.ToList();

            bool blnLeft = false;
            bool blnRight = false;
            if (lst.Count > )
            {
                if (DataSource.IndexOf(lst[]) > )
                {
                    blnLeft = true;
                }
                else
                {
                    blnLeft = false;
                }
                if (DataSource.IndexOf(lst[lst.Count - ]) >= DataSource.Count - )
                {
                    blnRight = false;
                }
                else
                {
                    blnRight = true;
                }
            }
            ShowBtn(blnLeft, blnRight);
            return lst;
        }

        /// <summary>
        /// 控制按钮显示
        /// </summary>
        /// <param name="blnLeftBtn">是否显示上一页，第一页</param>
        /// <param name="blnRightBtn">是否显示下一页，最后一页</param>
        protected virtual void ShowBtn(bool blnLeftBtn, bool blnRightBtn)
        { }

如此基类就完成了，看下完整代码

         protected virtual void ShowBtn(bool blnLeftBtn, bool blnRightBtn)
         { }
     }
 }

接下来就是具体的实现分页控件了，我们将实现2种不同样式的分页控件以适应不通的场景，

第一种

添加用户控件UCPagerControl，继承UCPagerControlBase

重新基类的部分函数

 private void panel1_MouseDown(object sender, MouseEventArgs e)
         {
             PreviousPage();
         }

         private void panel2_MouseDown(object sender, MouseEventArgs e)
         {
             NextPage();
         }

         private void panel3_MouseDown(object sender, MouseEventArgs e)
         {
             FirstPage();
         }

         private void panel4_MouseDown(object sender, MouseEventArgs e)
         {
             EndPage();
         }

         protected override void ShowBtn(bool blnLeftBtn, bool blnRightBtn)
         {
             panel1.Visible = panel3.Visible = blnLeftBtn;
             panel2.Visible = panel4.Visible = blnRightBtn;
         }

完成，是不是很简单，看下全部代码

     }
 }

第二种

这种和第一种的唯一区别就是页面计算生成的部分了

添加一个用户控件UCPagerControl2，继承UCPagerControlBase

属性如下

  public override event PageControlEventHandler ShowSourceChanged;

         private List<object> m_dataSource;
         public override List<object> DataSource
         {
             get
             {
                 return m_dataSource;
             }
             set
             {
                 m_dataSource = value;
                 if (m_dataSource == null)
                     m_dataSource = new List<object>();
                 ResetPageCount();
             }
         }
         private int m_intPageSize = ;
         public override int PageSize
         {
             get
             {
                 return m_intPageSize;
             }
             set
             {
                 m_intPageSize = value;
                 ResetPageCount();
             }
         }

其他更多的属性直接用基类的就可以

重写基类函数

         public override void FirstPage()
         {
             if (PageIndex == )
                 return;
             PageIndex = ;
             StartIndex = (PageIndex - ) * PageSize;
             ReloadPage();
             var s = GetCurrentSource();
             if (ShowSourceChanged != null)
             {
                 ShowSourceChanged(s);
             }
         }

         public override void PreviousPage()
         {
             if (PageIndex <= )
             {
                 return;
             }
             PageIndex--;

             StartIndex = (PageIndex - ) * PageSize;
             ReloadPage();
             var s = GetCurrentSource();
             if (ShowSourceChanged != null)
             {
                 ShowSourceChanged(s);
             }
         }

         public override void NextPage()
         {
             if (PageIndex >= PageCount)
             {
                 return;
             }
             PageIndex++;
             StartIndex = (PageIndex - ) * PageSize;
             ReloadPage();
             var s = GetCurrentSource();
             if (ShowSourceChanged != null)
             {
                 ShowSourceChanged(s);
             }
         }

         public override void EndPage()
         {
             if (PageIndex == PageCount)
                 return;
             PageIndex = PageCount;
             StartIndex = (PageIndex - ) * PageSize;
             ReloadPage();
             var s = GetCurrentSource();
             if (ShowSourceChanged != null)
             {
                 ShowSourceChanged(s);
             }
         }

        protected override void ShowBtn(bool blnLeftBtn, bool blnRightBtn)
         {
             btnFirst.Enabled = btnPrevious.Enabled = blnLeftBtn;
             btnNext.Enabled = btnEnd.Enabled = blnRightBtn;
         }

一个重置总页数的函数

  private void ResetPageCount()
         {
             if (PageSize > )
             {
                 PageCount = m_dataSource.Count / m_intPageSize + (m_dataSource.Count % m_intPageSize >  ?  : );
             }
             txtPage.MaxValue = PageCount;
             txtPage.MinValue = ;
             ReloadPage();
         }

一个重置计算当前页码列表的函数

  private void ReloadPage()
        {
            try
            {
                ControlHelper.FreezeControl(tableLayoutPanel1, true);
                List<int> lst = new List<int>();

                if (PageCount <= )
                {
                    for (var i = ; i <= PageCount; i++)
                    {
                        lst.Add(i);
                    }
                }
                else
                {
                    if (this.PageIndex <= )
                    {
                        for (var i = ; i <= ; i++)
                        {
                            lst.Add(i);
                        }
                        lst.Add(-);
