// 在此处放置用户代码以初始化页面
XmlDocument xdoc=new XmlDocument();
xdoc.Load(Server.MapPath("db.xml"));

// 创建一个XslTransform对象并导入XSL文件
XslTransform xslt=new XslTransform();
xslt.Load(Server.MapPath("del.xsl"));

XsltArgumentList argsList = new XsltArgumentList();
//Retrieve the pageNumber from querystring
int pageNumber = Convert.ToInt32(Request.QueryString["pagenumber"]);
//Add the required parameters to the XsltArgumentList object
argsList.AddParam("recordsPerPage","",10);//每页显示参数
argsList.AddParam("pageNumber","",pageNumber);
argsList.AddParam("recordCount","",77);
//Invoke the transform method, passing in the XsltArgumentList object
xslt.Transform(xdoc,argsList,Response.Output);
上面是page_load
xsl这样写:
<?xml version="1.0" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" />
<!--Set the paging characteristics - number of records per page and the page number and record count-->
<!-- Set the number of records per page-->
<xsl:variable name="recordsPerPage" select="77" />
<!-- Page Number field -->
<xsl:variable name="pageNumber" select="0" />
<!--Record Count Field-->
<xsl:variable name="recordCount" select="77" />
<xsl:template match="/">
