关于AspNetPager的用法（用于个人学习笔记）

 <div class="ArticleWrapPage">
            <asppager:AspNetPager ID="AspNetPager2" runat="server" HorizontalAlign="Center" PageSize="20"
                FirstPageText="首页" UrlPaging="true" LastPageText="末页" NextPageText="下页" PrevPageText="上页"
                ShowCustomInfoSection="Left" CustomInfoHTML="当前页：<font color='red'><b>%currentPageIndex%</b></font>&nbsp;&nbsp;共 <font color='red'><b>%PageCount%</b></font> 页 当前记录数：%RecordCount%"
                AlwaysShow="True" CloneFrom="AspNetPager1">
            </asppager:AspNetPager>
        </div>
        <div class="ArticleSear">
            <asp:Repeater runat="server" ID="repArticleShow">
             
                <ItemTemplate>

                        <%#TiHuangString(Eval("ARTICLE_CONTENT_PURE"))%>

    </div>

        <pages>
            <controls>
                <add tagPrefix="asppager" namespace="Wuqi.Webdiyer" assembly="AspNetPager"/>
            </controls>
        </pages>

       

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                BindCount();
            }
        }

                if (WebSite == 5)

                }
                AspNetPager1.RecordCount = SearchBLL.IndexSearchNewCount(KeyWord, WebSite);
                //repArticleShow.DataSource = SearchBLL.IndexSearch(KeyWord, WebSite, AspNetPager1.StartRecordIndex - 1, AspNetPager1.PageSize);
                //repArticleShow.DataBind();
            }
            else
            {
                   AspNetPager1.PageSize = PageSize;
                AspNetPager1.RecordCount = SearchBLL.AdvSearchCount(MainTitle, FitTitle, Content, KeyWord, SortGroup, Term, DateGroup, SelectDate, StartTime, EndTime, WebSite, Server.UrlDecode(STR_CHANNEL_WEB_CLASS), columnids);            }
        }

        protected void AspNetPager1_PageChanged(object sender, EventArgs e)
        {
            Bind();
        }

这里要注意的是UrlPaging的设置，当你设置为true的时候是通过url来传递参数的，那么后台页面每次都会执行PostBack。

如果设置为false，那么是用表单提交的方式，viewstate里面有保存表单的视图，是属于回发的。

另外页面每一次重新加载都会触发 OnPageChanged      事件
