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

 1  public interface IPageControl
 2     {
 3         /// <summary>
 4         /// 数据源改变时发生
 5         /// </summary>
 6         event PageControlEventHandler ShowSourceChanged;
 7         /// <summary>
 8         /// 数据源
 9         /// </summary>
10         List<object> DataSource { get; set; }
11         /// <summary>
12         /// 显示数量
13         /// </summary>
14         int PageSize { get; set; }
15         /// <summary>
16         /// 开始下标
17         /// </summary>
18         int StartIndex { get; set; }
19         /// <summary>
20         /// 第一页
21         /// </summary>
22         void FirstPage();
23         /// <summary>
24         /// 前一页
25         /// </summary>
26         void PreviousPage();
27         /// <summary>
28         /// 下一页
29         /// </summary>
30         void NextPage();
31         /// <summary>
32         /// 最后一页
33         /// </summary>
34         void EndPage();
35         /// <summary>
36         /// 重新加载
37         /// </summary>
38         void Reload();
39         /// <summary>
40         /// 获取当前页数据
41         /// </summary>
42         /// <returns></returns>
43         List<object> GetCurrentSource();
44         /// <summary>
45         /// 总页数
46         /// </summary>
47         int PageCount { get; set; }
48         /// <summary>
49         /// 当前页
50         /// </summary>
51         int PageIndex { get; set; }
52     }

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

 1 /// <summary>
 2         /// 总页数
 3         /// </summary>
 4         public virtual int PageCount
 5         {
 6             get;
 7             set;
 8         }
 9         private int m_pageIndex = 1;
10         /// <summary>
11         /// 当前页码
12         /// </summary>
13         public virtual int PageIndex
14         {
15             get { return m_pageIndex; }
16             set { m_pageIndex = value; }
17         }
18         /// <summary>
19         /// 关联的数据源
20         /// </summary>
21         public virtual List<object> DataSource { get; set; }
22         public virtual event PageControlEventHandler ShowSourceChanged;
23         private int m_pageSize = 1;
24         /// <summary>
25         /// 每页显示数量
26         /// </summary>
27         [Description("每页显示数量"), Category("自定义")]
28         public virtual int PageSize
29         {
30             get { return m_pageSize; }
31             set { m_pageSize = value; }
32         }
33         private int startIndex = 0;
34         /// <summary>
35         /// 开始的下标
36         /// </summary>
37         [Description("开始的下标"), Category("自定义")]
38         public virtual int StartIndex
39         {
40             get { return startIndex; }
41             set
42             {
43                 startIndex = value;
44                 if (startIndex <= 0)
45                     startIndex = 0;
46             }
47         }

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 = 0;
            var s = GetCurrentSource();

            if (ShowSourceChanged != null)
            {
                ShowSourceChanged(s);
            }
        }
        /// <summary>
        /// 上一页
        /// </summary>
        public virtual void PreviousPage()
        {
            if (DataSource == null)
                return;
            if (startIndex == 0)
                return;
            startIndex -= m_pageSize;
            if (startIndex < 0)
                startIndex = 0;
            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 < 0)
                startIndex = 0;
            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 < 0)
                startIndex = 0;
            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, 0, intShowCount);
            var lst = objs.ToList();

            bool blnLeft = false;
            bool blnRight = false;
            if (lst.Count > 0)
            {
                if (DataSource.IndexOf(lst[0]) > 0)
                {
                    blnLeft = true;
                }
                else
                {
                    blnLeft = false;
                }
                if (DataSource.IndexOf(lst[lst.Count - 1]) >= DataSource.Count - 1)
                {
                    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

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

 1 private void panel1_MouseDown(object sender, MouseEventArgs e)
 2         {
 3             PreviousPage();
 4         }
 5 
 6         private void panel2_MouseDown(object sender, MouseEventArgs e)
 7         {
 8             NextPage();
 9         }
10 
11         private void panel3_MouseDown(object sender, MouseEventArgs e)
12         {
13             FirstPage();
14         }
15 
16         private void panel4_MouseDown(object sender, MouseEventArgs e)
17         {
18             EndPage();
19         }
20 
21         protected override void ShowBtn(bool blnLeftBtn, bool blnRightBtn)
22         {
23             panel1.Visible = panel3.Visible = blnLeftBtn;
24             panel2.Visible = panel4.Visible = blnRightBtn;
25         }

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

 1  public override event PageControlEventHandler ShowSourceChanged;
 2 
 3         private List<object> m_dataSource;
 4         public override List<object> DataSource
 5         {
 6             get
 7             {
 8                 return m_dataSource;
 9             }
10             set
11             {
12                 m_dataSource = value;
13                 if (m_dataSource == null)
14                     m_dataSource = new List<object>();
15                 ResetPageCount();
16             }
17         }
18         private int m_intPageSize = 0;
19         public override int PageSize
20         {
21             get
22             {
23                 return m_intPageSize;
24             }
25             set
26             {
27                 m_intPageSize = value;
28                 ResetPageCount();
29             }
30         }

其他更多的属性直接用基类的就可以

重写基类函数

 1         public override void FirstPage()
 2         {
 3             if (PageIndex == 1)
 4                 return;
 5             PageIndex = 1;
 6             StartIndex = (PageIndex - 1) * PageSize;
 7             ReloadPage();
 8             var s = GetCurrentSource();
 9             if (ShowSourceChanged != null)
10             {
11                 ShowSourceChanged(s);
12             }
13         }
14 
15         public override void PreviousPage()
16         {
17             if (PageIndex <= 1)
18             {
19                 return;
20             }
21             PageIndex--;
22 
23             StartIndex = (PageIndex - 1) * PageSize;
24             ReloadPage();
25             var s = GetCurrentSource();
26             if (ShowSourceChanged != null)
27             {
28                 ShowSourceChanged(s);
29             }
30         }
31 
32         public override void NextPage()
33         {
34             if (PageIndex >= PageCount)
35             {
36                 return;
37             }
38             PageIndex++;
39             StartIndex = (PageIndex - 1) * PageSize;
40             ReloadPage();
41             var s = GetCurrentSource();
42             if (ShowSourceChanged != null)
43             {
44                 ShowSourceChanged(s);
45             }
46         }
47 
48         public override void EndPage()
49         {
50             if (PageIndex == PageCount)
51                 return;
52             PageIndex = PageCount;
53             StartIndex = (PageIndex - 1) * PageSize;
54             ReloadPage();
55             var s = GetCurrentSource();
56             if (ShowSourceChanged != null)
57             {
58                 ShowSourceChanged(s);
59             }
60         }
61  
62        protected override void ShowBtn(bool blnLeftBtn, bool blnRightBtn)
63         {
64             btnFirst.Enabled = btnPrevious.Enabled = blnLeftBtn;
65             btnNext.Enabled = btnEnd.Enabled = blnRightBtn;
66         }

一个重置总页数的函数

 1  private void ResetPageCount()
 2         {
 3             if (PageSize > 0)
 4             {
 5                 PageCount = m_dataSource.Count / m_intPageSize + (m_dataSource.Count % m_intPageSize > 0 ? 1 : 0);
 6             }
 7             txtPage.MaxValue = PageCount;
 8             txtPage.MinValue = 1;
 9             ReloadPage();
10         }

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 <= 9)
                {
                    for (var i = 1; i <= PageCount; i++)
                    {
