AspNetPager分页+URL重写

web.config配置文件中url重写规则：

 

 <RewriterRule>
        <LookFor>~/NewsList_([0-9]*).html</LookFor>
        <SendTo><![CDATA[~/NewsList.aspx?page=$1]]></SendTo>
</RewriterRule>

 

 

 NewsList.aspx：

 

  <webdiyer:AspNetPager ID="AspNetPager1" runat="server" OnPageChanged="AspNetPager1_PageChanged"
                            PageSize="10" AlwaysShow="true" CssClass="anpager" CurrentPageButtonClass="cpb" ShowPageIndexBox="never"
                            FirstPageText="首页" LastPageText="尾页" NextPageText="后页" PrevPageText="前页" EnableUrlRewriting="true" UrlRewritePattern="./NewsList_{0}.html">
                        </webdiyer:AspNetPager>

 

 

NewsList.aspx.cs：

 

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

   void BindPagedData()
    {      
        procAllTablesPage _patp = new procAllTablesPage();
        DataSet ds = _patp.Query("news", "*", "id", AspNetPager1.PageSize, 1, 0, 1, " and status<>0");
        AspNetPager1.RecordCount = int.Parse(ds.Tables[1].Rows[0][0].ToString());
        rptNewsList.DataSource = ds;
        rptNewsList.DataBind();
    }

 

 

分页存储过程：

 

CREATE  PROCEDURE [dbo].[procAllTablesPage]
@tblName varchar(255), -- 表名
@strGetFields nvarchar(1000) = "*", -- 需要返回的列
@fldName varchar(255)='', -- 排序的字段名
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@doCount bit = 0, -- 返回, 非0 值则返回记录总数
@OrderType bit = 0, -- 设置排序类型, 非0 值则降序
@strWhere varchar(1500) = '' -- 查询条件(注意: 不要加where)
AS
declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序类型

if @doCount != 0
begin
   if @strWhere !=''
    set @strSQL = 'select count(*) as Total from [' + @tblName + '] where 1=1 '+ @strWhere
   else
    set @strSQL = 'select count(*) as Total from [' + @tblName + ']'
end --以上代码的意思是如果@doCount传递过来的不是，就执行总数统计。以下的所有代码都是@doCount为0的情况：
else
begin
   if @OrderType != 0--降序
   begin
    set @strTmp = '<(select min'
    set @strOrder = ' order by [' + @fldName +'] desc'--如果@OrderType不是0，就执行降序，这句很重要！
   end
   else
   begin
    set @strTmp = '>(select max'
    set @strOrder = ' order by [' + @fldName +'] asc'
   end
   if @PageIndex = 1
   begin
    if @strWhere != ''
     set @strSQL = 'select top ' + str(@PageSize) +' ' + @strGetFields + ' from [' + @tblName + '] where 1=1 ' + @strWhere + ' ' + @strOrder
    else
     set @strSQL = 'select top ' + str(@PageSize) +' ' + @strGetFields + ' from [' + @tblName + '] ' + @strOrder--如果是第一页就执行以上代码，这样会加快执行速度
   end
   else
   begin--以下代码赋予了@strSQL以真正执行的SQL代码
    set @strSQL = 'select top ' + str(@PageSize) + ' ' + @strGetFields + ' from ['   + @tblName + '] where [' + @fldName + ']' + @strTmp + '(['+ @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' [' + @fldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)' + @strOrder
    if @strWhere != ''
     set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from [' + @tblName + '] where [' + @fldName + ']' + @strTmp + '([' + @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' [' + @fldName + '] from [' + @tblName + '] where 1=1 ' + @strWhere + ' ' + @strOrder + ') as tblTmp) and 1=1 ' + @strWhere + ' ' + @strOrder
   end
   if @strWhere !=''            --得到记录的总行数
    set @strSQL =@strSQL+ '; select count(*) as Total from [' + @tblName + '] where 1=1 '+ @strWhere
   else
    set @strSQL =@strSQL+ '; select count(*) as Total from [' + @tblName + ']'
end
exec (@strSQL)
RETURN
