I need to fetch data from the list (which I am getting in XML) and then I need to apply the XML data to my XSLT so that it can produce HTML output.

I tried using SPUtility.GetGenericSetupPath to get the XSLT which resides in 14 hive but SPUtility.GetGenericSetupPath doesn't supported in Sandbox web parts.

I got that I will be uploading my XSLT somewhere into SharePoint Library, but the real question is How will I consume it?

SPUtility.GetGenericSetupPath to get the XSLT isn't working in Sandbox.

How will I get the path of XSLT?

This is what I have done with Farm Web Part, now I'm converting it into Sandbox Web Part.

            //Transform XML To HTML using ContactList.XSLT
            XslCompiledTransform XMLTrnsfrm = new XslCompiledTransform();

Any other solution in mind guys?

In a sandboxed solution you'll not be able to read from the file system so you need to put the XSLT file into a SharePoint document library then read it like this:

var file = web.GetFile(pathToXslt);
var bytes = file.OpenBinary();
var stream = new MemoryStream(bytes);
var reader = new XmlTextReader(stream);
var XMLTransfrm = new XslCompiledTransform();
  • When you say pathToXslt, you mean the full path to the xslt? like "mysharepointsite.com/sites/doclib/myxslt.xslt" ??

  • Also, file.OpenBinaryStream() is not working, OpenBinaryStream is throwing an error because It's not Available in Sandboxed Solutions.

  • It can be either the full path http://mysharepointsite.com/sites/MySite/doclib/myxslt.xslt, server relative /sites/MySite/doclib/myxslt.xslt or site relative doclib/myxslt.xslt Commented Oct 8, 2012 at 8:02
  • It's throwing Request for the permission of type 'System.Net.WebPermission, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

  • What I did is just, XMLTrnsfrm.Load("mysharepointsite.com/sites/MySite/doclib/myxslt.xslt");
