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;

115 private system.windows.forms.panel panel1;
116 }
117 }
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();
