分页效果:
废话不多讲,直接上代码
1.建立一个用户控件
1 <%@ Control Language="C#" AutoEventWireup="true" CodeFile="pagination1.ascx.cs" Inherits="userControl_pagination1" %>
2 <style type="text/css">
3 .pagination{
4 overflow:hidden;
5 margin:0;
6 padding:10px 10px 6px 10px;
7 _zoom:1;
8 }
9 .pagination *{
10 display:inline;
11 float:left;
12 margin:0;
13 padding:0;
14 font-size:12px;
15 }
16 .currentPage b{
17 float:none;
18 color:#f00;
19 }
20 .pagination li{
21 list-style:none;
22 margin:0 5px;
23 }
24 .pagination li li{
25 position:relative;
26 margin:-2px 0 0;
27 font-family: Arial, Helvetica, sans-serif
28 }
29 .firstPage a,.previousPage a,.nextPage a,.lastPage a{
30 overflow:hidden;
31 height:0;
32 text-indent:-9999em;
33 border-top:8px solid #fff;
34 border-bottom:8px solid #fff;
35 }
36 .pagination li li a{
37 margin:0 1px;
38 padding:0 4px;
39 border:3px double #fff;
40 +border-color:#eee;
41 background:#eee;
42 color:#06f;
43 text-decoration:none;
44 }
45 .pagination li li a:hover{
46 background:#f60;
47 border-color:#fff;
48 +border-color:#f60;
49 color:#fff;
50 }
51 li.firstPage{
52 margin-left:40px;
53 border-left:3px solid #06f;
54 }
55 .firstPage a,.previousPage a{
56 border-right:12px solid #06f;
57 }
58 .firstPage a:hover,.previousPage a:hover{
59 border-right-color: #f60;
60 }
61 .nextPage a,.lastPage a{
62 border-left:12px solid #06f;
63 }
64 .nextPage a:hover,.lastPage a:hover{
65 border-left-color:#f60;
66 }
67 li.lastPage{
68 border-right:3px solid #06f;
69 }
70 li li.currentState a{
71 position:relative;
72 margin:-1px 3px;
73 padding:1px 4px;
74 border:3px double #fff;
75 +border-color:#f60;
76 background:#f60;
77 color:#fff;
78 }
79 li.currentState,.currentState a,.currentState a:hover{
80 border-color:#fff #ccc;
81 cursor:default;
82 }
83 </style>
84 <div class="pagination">
85 <ul>
86 <li>
87 <%=paginationStr%><br />
88 </li>
89 </ul>
90 </div>

3. 调用方法
建立一个aspx 页面,将上面的用户控件拖放到页面目标位置,相信这个大家都会
来看看后台是怎么使用的吧

11 public partial class userControl_Default2 : System.Web.UI.Page
12 {
13 public int page_index = 1;
14 protected void Page_Load(object sender, EventArgs e)
15 {
16 if (Request.QueryString["page"] != null) {
17 page_index = Convert.ToInt32(Request.QueryString["page"]);
18 }
19 table_bind2();
20 }
21

23 {
24 string SqlStr = "SELECT COUNT(1) FROM sys_user";
25 string data_count = string.Format("{0}", sqlHelper.ExecuteScalar(sqlHelper.sqlConnectonStr
26 , CommandType.Text, SqlStr, null));

28 + (2 * (page_index - 1)) + " usr_id FROM sys_user ORDER BY usr_id ) A )";
29 GridView1.DataSource = sqlHelper.ExecuteDataTable(sqlHelper.sqlConnectonStr, CommandType.Text, SqlStr, null);
30 GridView1.DataBind();
31 pagination11.Page_Count = data_count;
