用AspNetPager控件最详细的分页实现方法（亲自实践）
祝贺一下~好不容易把分页做出来了。之前都是用GridView自带的分页，版式难看不说，还极不优化，一次取出所有记录，然后进行假分页。
现在用AspNetPager控件做出的真分页，就好多了，不过还有改进的地方，SQL语句如果换成存储过程效率会更高。
首先在SqlHelper.cs（DAL层中的数据库助手类，用于写可以复用的基本增删查改方法）中加上以下代码：
Code
/**//// <summary>
/// 获取分页数据
/// </summary>
/// <param name="sql">sql语句</param>
/// <param name="currentPage">当前页</param>
/// <param name="pagesize">每页显示数</param>
/// <param name="recordcount"></param>
/// <returns></returns>
public static DataSet GetPage(string sql, int currentPage, int pagesize, out int recordcount)
{
openCon();
sqlDs.Clear();
sqlDa = new SqlDataAdapter(sql, sqlConn);
int startRow = (currentPage - 1) * pagesize;
sqlDa.Fill(sqlDs, startRow, pagesize, "table");
recordcount = GetPageRecord(sql);
closeCon();
return sqlDs;
}
//返回总的记录数
public static int GetPageRecord(string sql)
{
openCon();
sql = Regex.Replace(sql, "order by.*", "");
sql = "select count(*) from (" + sql + ") as temp";
sqlCmd = new SqlCommand(sql, sqlConn);
int recordcount = int.Parse(sqlCmd.ExecuteScalar().ToString());
closeCon();
return recordcount;
}
然后在BLL层新建一个PageManager.cs的分页操作类，封装一下DAL层方法：
Code
/**//// <summary>
/// 获取分页数据
/// </summary>
/// <param name="sql">sql语句</param>
/// <param name="currentPage">当前页</param>
/// <param name="pagesize">每页显示数</param>
/// <param name="recordcount"></param>
/// <returns></returns>
public static DataSet GetPage(string sql, int currentPage, int pagesize, out int recordcount)
{
return SQLHelper.GetPage(sql, currentPage, pagesize, out recordcount);
}
ASP.NET需分页的数据绑定处是这样的：
Code
<asp:Repeater ID="repNewsList" runat="server">
<ItemTemplate>
<tr>
<td align="center"><a href="list.aspx?caid=<%# Eval("caId") %>"><%# Eval("name") %></a></td>
<td align="center"><%# Eval("createTime") %></td>
</tr>
</ItemTemplate>
</asp:Repeater>
然后在绑定代码下方加上分页控件(当然这个可以随便放，怎么好看怎么放)：
Code
<!--分页控件-->
<div style="text-align:center; height:50px; line-height:50px;">
<webdiyer:AspNetPager ID="AspNetPager1" runat="server" AlwaysShow="True" UrlPaging="true"
FirstPageText="首页" LastPageText="末页" NextPageText="下一页" NumericButtonCount="5"
onpagechanged="AspNetPager1_PageChanged" PagingButtonSpacing="10px" NumericButtonTextFormatString="[{0}]"
PrevPageText="上一页" SubmitButtonText="Go" TextAfterPageIndexBox="页"
TextBeforePageIndexBox="转到" ShowCustomInfoSection="Left"
CustomInfoHTML="目前是第%CurrentPageIndex%页 / 总共%PageCount%页">
</webdiyer:AspNetPager>
</div>
最后在aspx.cs中加上数据的分页绑定方法（这里的SQL语句要根据列表显示的需要进行调整）：
Code
/**//// <summary>
/// 绑定带有分页的新闻列表
/// </summary>
public void BindRepeater()
{
int caid = int.Parse(Request.QueryString["caid"]);
string Sql = "select * from news where caId=" + caid + " order by createTime desc";
int CurrentPage = AspNetPager1.CurrentPageIndex;
int PageSize = AspNetPager1.PageSize;
int RecordCount;
DataSet ds = PageManager.GetPage(Sql, CurrentPage, PageSize, out RecordCount);
AspNetPager1.RecordCount = RecordCount;
AspNetPager1.CustomInfoHTML += " 共" + RecordCount + "条新闻</b>";
repNewsList.DataSource = ds;
repNewsList.DataBind();
}
别忘了，在page_load调用一下：
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindRepeater();
}
}
还有分页控件的PageChanged事件里也调用一下：
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
BindRepeater();
}
最后再补充一个非常漂亮的翻页样式，清爽超酷型~：
Code
<style>
.anpager
{}{
font-size:12px;
}
.anpager .cpb
{}{
background:#1F3A87 none repeat scroll 0 0;
border:1px solid #CCCCCC;
color:#FFFFFF;
font-weight:bold;
margin:5px 4px 0 0;
padding:4px 5px 0;
}
.anpager a
{}{
background:#FFFFFF none repeat scroll 0 0;
border:1px solid #CCCCCC;
color:#1F3A87;
margin:5px 4px 0 0;
padding:4px 5px 0;
text-decoration:none
}
.anpager a:hover
{}{
background:#1F3A87 none repeat scroll 0 0;
border:1px solid #1F3A87;
color:#FFFFFF;
}
</style>
然后在AspNetPager中加上以下四个属性，搞定！
CssClass="anpager"
CurrentPageButtonClass="cpb"
CustomInfoClass=""
CustomInfoTextAlign="Left"
OK，分页大功告成。 本人QQ:3053166 希望和.net爱好者交流~
