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

252         { }
253     }
254 }

 

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

(十二)c#Winform自定义控件-分页控件

 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

(十二)c#Winform自定义控件-分页控件

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;
