AspNetPager分页功能总结

下载AspNetPager.dll文件，放到项目bin文件夹中，并在项目中引用，然后添加到工具栏，可以实现拖拽控件了

拖拽AspNetPager到项目文件中，我的是用的repeater控件，拖拽到这个控件的底部，然后在aspx页面中，第二行代码中会多出

<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

这么一句，然后在repeater控件下边会有一个

<webdiyer:AspNetPager ID="AspNetPager1" runat="server">
</webdiyer:AspNetPager>

对AspNetPager控件编辑其属性

<webdiyer:AspNetPager ID="PageCtrl" runat="server" PageSize="5" 
                      HorizontalAlign="Center" Width="100%" 
                      meta:resourceKey="AspNetPager1" Style="font-size: 10px"
                    AlwaysShow="false" FirstPageText="首页" LastPageText="尾页" NextPageText="下一页" 
                      PrevPageText="上一页" SubmitButtonText="Go"  SubmitButtonClass="submitBtn"
                    CustomInfoStyle="font-size:14px;text-align:left;" 
                      InputBoxStyle="25px; border:1px solid #999999; text-align:center; " 
                      TextBeforeInputBox="转到第" TextAfterInputBox="页 " PageIndexBoxType="TextBox" 
                      ShowPageIndexBox="Always" TextAfterPageIndexBox="页" 
                      TextBeforePageIndexBox="转到" Font-Size="10px" CustomInfoHTML="共&lt;font color='#ff0000'&gt;%PageCount%&lt;/font&gt;页，第<font color='#ff0000'>%CurrentPageIndex%</font>页" 
                      ShowCustomInfoSection="Left" CustomInfoSectionWidth="19%" 
                      PagingButtonSpacing="3px" onpagechanged="AspNetPager1_PageChanged">
        </webdiyer:AspNetPager>

具体都是什么自己有时间去查吧我也不太了解

aspx页面文件基本搞定，后台代码中我把一些东西写到操作类中了

：取出每一页中的数据

/// <summary>
        /// 分页
        /// </summary>
        /// <returns>返回DataTable数据集</returns>
        public DataTable SelectAll(int startIndex,int size)
        {
            DataTable dt = new DataTable();
            string sql = @"select * from  
                            ( select *, ROW_NUMBER() OVER(Order by  id asc ) AS RowNumber from category)   b 
                            where RowNumber BETWEEN '" + startIndex + "' and '" + size + "' ";
            dt = sqlhelper.ExecuteQuery(sql,CommandType.Text);
            return dt;
        }

取出总的页数

/// <summary>
        /// 取出当前所有新闻分类总条数
        /// </summary>
        /// <returns>返回DataTable数据集</returns>
        public int SelectCaCount()
        {
            int MyCount;
            string sql = @"select count(0) from category    ";
            MyCount=new SQLHelper().GetRecordCount(sql);
            return MyCount;
        }

用到的sqlhelper类中的方法有：

/// <summary>
        /// ExecuteScalar--返回首行首列 
        /// </summary>
        /// <param name="XSqlString">sql语句</param>
        /// <returns>返回结果集的首行首列</returns>
        public int GetRecordCount(string XSqlString)
        {
            string SCount;

            SqlCommand Cmd = new SqlCommand(XSqlString, GetConn());
            SCount = Cmd.ExecuteScalar().ToString().Trim(); //返回结果集的首行首列,忽略其它
            if (SCount == "")
                SCount = "0";

            return Convert.ToInt32(SCount);
        }

/// <summary>
        /// 执行带参数的增删改SQL语句或存储过程
        /// </summary>
        /// <param name="sql">带参数的增删改SQL语句或存储过程</param>
        /// <param name="ct">命令类型</param>
        /// <returns></returns>
        public DataTable ExecuteQuery(string cmdText,CommandType ct)
        {
            DataTable dt = new DataTable();
            cmd = new SqlCommand(cmdText, GetConn());
            cmd.CommandType = ct;
            using (sdr = cmd.ExecuteReader(CommandBehavior.CloseConnection))
            {
                dt.Load(sdr);
            }
            return dt;
        }

public SQLHelper()
        {
            string connStr = ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
            conn = new SqlConnection(connStr);
        }

        private SqlConnection GetConn()
        {
            if (conn.State==ConnectionState.Closed)
            {
                conn.Open();
            }
            return conn;
        }
