asp.net 通过aspnetpager为DataList分页

<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>

 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(); 
}
