asp.net 通过aspnetpager为DataList分页

2019-06-26 12:44ASP.NET之家 ASP.NET教程

今天整了半天才把DataList的分页搞定，下面把我的设计过程给大家讲讲

前台代码：
代码

<div id="newslistdiv">

<asp:DataList ID="NewsList" runat="server" Width="820px">

<HeaderTemplate>

<div>

<img src="../loginimages/newslisthead.gif" alt="" /></div>

</HeaderTemplate>

<ItemTemplate>

<dl>

<dd>

·<a href="#" class="rlk" onclick='window.location.href="DetailNews.aspx?ID=<%#Eval("NewsID") %>"'><%#Eval("NewsTitle") %></a>

   <%#Eval("NewsTime", "{0:yyyy-MM-dd}")%><br />

</dd>

</dl>

</ItemTemplate>

</asp:DataList>

</div>

<div style="margin-bottom: 2px;" align="center">

<webdiyer:AspNetPager ID="AspNetPager1" runat="server" PageSize="15" FirstPageText=" 首页 "

LastPageText=" 尾页 " NextPageText=" 下一页 " OnPageChanged="AspNetPager1_PageChanged"

PrevPageText=" 上一页 " Width="100%" AlwaysShow="true" CssClass="anpager">

</webdiyer:AspNetPager>

</div>

后台代码：

代码

复制代码代码如下:

	
	protected void Page_Load(object sender, EventArgs e) 

	{ 

	if (!IsPostBack) 

	{ 

	BindNewsDatalist(); 

	} 

	} 

	//绑定DataList的数据源 

	private void BindNewsDatalist() 

	{ 

	FJDWS.BusinessLogic.LNewsManager lnewsmanager = new FJDWS.BusinessLogic.LNewsManager(); 

	this.AspNetPager1.RecordCount = lnewsmanager.FindAll().Count; 

	PagedDataSource pds = new PagedDataSource(); //定义一个PagedDataSource类来执行分页功能 

	pds.DataSource = lnewsmanager.FindAll(); 

	pds.AllowPaging = true; 

	pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1; 

	pds.PageSize = AspNetPager1.PageSize; 

	this.NewsList.DataSource = pds; 

	NewsList.DataBind(); 

	} 

	protected void AspNetPager1_PageChanged(object src, EventArgs e) 

	{ 

	//AspNetPager1.CurrentPageIndex = e.NewPageIndex; 

	BindNewsDatalist(); 

	}
