<div id="newslistdiv"> 
<asp:DataList ID="NewsList" runat="server" Width="820px"> 
<HeaderTemplate> 
<div> 
<img src="../loginimages/newslisthead.gif" alt="" /></div>

·<a rel="nofollow noopener noreferrer" href="#" class="rlk" onclick='window.location.rel="nofollow noopener noreferrer" 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"

//绑定DataList的数据源

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)
