Your code would work as it does in any other situation... but the trick is that you need to make sure that your XSLT file is included as part of the form template resources. Otherwise you will not be able to load it because the template will refuse to believe that it exists.

Hi,

I want to put my XSLT in my XSN. I want to make an xsl transformation
when I am in infopath:

XslTransform xslt = new XslTransform();
xslt.Load("myxslt.xslt");

That can be done?

How can I do for call my xslt in my code is it correct like this?

Thanks
