I am trying to add paging to the data that I am displaying on screen, but it doesn't work. Whenever data is returned it is always the complete dataset (over 100 records, which should produce a page for every 10 records), and it always starts on page number 0. Here is my code :

XSL :

<?xml version="1.0" encoding="UTF-8" ?>

<xsl:stylesheet version="1.0" xmlns:xsl=" xmlns:asp="Remove">

<xsl:eek:utput method="html" />

<xsl:param name="discount" select="0.5" />

<xsl:template match="/">

<!--Set the paging characteristics - number of records per page, page number and record count-->

<!--Set the number of records per page-->

<xsl:param name="recordsPerPage" select="504" />

<!--Page number field-->

<xsl:param name="pageNumber" select="0" />

<!--Record count field-->

<xsl:param name="recordCount" select="504" />

Stored procedure :

CREATE procedure dbo.ViewUserListForXml

as

SELECT u.userKey as 'UserKey',
t.teammanager as 'TeamManager',
l.teamtype as 'TeamType',
l.teamtypeid as 'TeamTypeID',
t.teamkey as 'TeamKey',
u.territorycode as 'TerritoryCode',
u.userName as 'UserName',
u.userLogin as 'UserLogin',
u.userPassword as 'Password',
u.userEmail as 'Email',
u.region as 'Region',
u.businessunit as 'BusinessUnit',
u.lastLoginDate as 'LastLogin',
u.active as 'Active',
'100' as 'NumericExample'
FROM UserLogin u INNER JOIN
Teams t ON t.TeamKey = u.ClientSiteKey inner join
lookup_TeamTypes l on l.teamtypeid = t.TeamTypeID
ORDER BY u.UserName
For Xml raw
GO

C# :

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.Xml;

using System.Xml.Xsl;

using System.IO;

using System.Xml.XPath;

using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

SqlConnection objConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["XeroxConnectionString"].ConnectionString);

objConnection.Open();

SqlCommand cmd = new SqlCommand();

cmd.CommandText = "ViewUserListForXml";

cmd.CommandType = CommandType.StoredProcedure;

cmd.Connection = objConnection;

XmlReader reader = cmd.ExecuteXmlReader();

XPathDocument xpathDoc = new XPathDocument(reader);

objConnection.Close();

XslCompiledTransform transform = new XslCompiledTransform();

string xslPath = Request.PhysicalApplicationPath + "xslViewUserList.xslt";

transform.Load(xslPath);

XsltArgumentList argsList = new XsltArgumentList();

int pageNumber = Convert.ToInt32(Request.QueryString["pagenumber"]);

argsList.AddParam("recordsPerPage", "", 10);

argsList.AddParam("pageNumber", "", pageNumber);

argsList.AddParam("recordCount", "", 504);

transform.Transform(xpathDoc, argsList, Response.Output);

}

}



Any assistance would be much appreciated, this is the first time I am using XSL so the more advanced stuff in this is proving difficult!
