One step xsl:fo transformation / pdf render

May 20, 2009 at 8:55 AM

C# .net 2.0


I'm struggling to get my code working and would appreciate any help you can give me.

I have a .fo file which I can render to pdf no problem when I use the actual file from the file system and change the content type to 'Application/pdf', however, when I use the output from an xsl transformation within the code, and use that to generate an in-memory .fo, I get a .net error: "System.SystemException: Unknown formatting object^root".

The thing is, when I write the in-memory .fo to the screen, and compare with the .fo from the file system, they're identical, so really stumped how to fix this.


Many thanks for any tips,

I realised that I had two xmlns for fo in the xsl stylesheet.  Once I removed that, I moved on a step.

My issue now is that whilst the pdf data is written to the screen, I've changed the content type to pdf so it should be opening _as_ a pdf, but it isn't.  If I save the page asa .pdf and open in a pdf reader, it's a perfectly valid pdf document, so I'm obviously missing something fundamental...

Okay, after a bit of googling, I've found the correct syntax to write it to the screen...:


Response.BinaryWrite([memorystream of pdf].ToArray());
