通过aspnetpager为DataList分页

     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：

 

<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>
                        &nbsp;&nbsp;&nbsp;<%#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：

 

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();
        }
