[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] client side paging using XML, XSLT, and script from w
 Hi All,
I am in need of some desperate help here. I am attempting to use the article
found on http://www.bayes.co.uk with respect to client side paging using XML
and XSLT. I have searched high and low on the web and have not managed to
find an answer/solution to my problem. Hoping someone can help.
Basically, I am using ASP.Net and SQL Server to return to me a randomised
result set. I then manually build up a XML document and use the stylesheet
example and javascript function from the bayes website to do the client side
paging. It filters nicely, i.e. displaying only 5 records, but when I click
the next 'button' and it executes the javascript it gives me an "object
error".
It seems to be at this point: "navigator.XSLDocument.xml" - undefined.
Remember my XML is created manually and dynamically.
I have found an article on the list that has the same problem, but there
does not seem to be a solution. Can someone please help. Below are code
extracts to help explain....
Thanx in advance
--------------------- ASP.Net C# code extract Start
------------------------------------------
System.IO.StringReader strReader = new System.IO.StringReader(xmlData);
xpathDoc = new XPathDocument(strReader); XslTransform transform = new
XslTransform(); transform.Load(Server.MapPath("results_page.xslt"));
transform.Transform(xpathDoc,null,Response.Output,new XmlUrlResolver());
--------------------- ASP.Net C# code extract End
------------------------------------------
-------------------------------- XML Start
---------------------------------------------------
