sql server reporting services : Extend CSV Rendering

Is there anyway to extend the existing CSV rending to change deviceinfo
settings that would be used when export is selected from the standard
ReportServer interface.

Example would be to have TXT rendering capability that used the CSV
rendering components, but changed the deviceinfo settings so that
Extension=txt, FieldDelimiter=|. I want to use the parameter selection
capability, and then allow the user to export to this TXT format instead of
CSV.

Logically I would think that you could added some DeviceInfo settings to the
config file in the Report Service directory where Render is defined. But I
am unable to find any sort of documentation.

Also the BOL talks about extending existing rendering formats, as opposed to
create custom rendering extensions. I have yet to find out how it is
possible to extend the CSV rendering extension to accomplish this. I really
want to be able to leverage the existing CSV rendering extension, to modify
a couple of settings.

I know that this can be done via URL and Hidden values in the calling web
page that shells the Report Services window. But when you click the Export
functionality and pick CSV none of the CSV deviceinfo settings are carried
forward to the Export window that is opened before prompting to Save or Open
the file.

Thanks,
Mike

Unfortunately, we do not support setting the device info through report
manager.

Regarding the BOL reference to extending rather than writing your own: I
think this might just be a case of terminology confusion. You cannot extend
a particular format. You can extend the report server by adding your own
formats. I'll see about getting the wording changed.

Thanks for the information. Maybe this could be a wishlist type item?

Yes, we plan (at some point :-)) to expose UI around device info settings.

Lukasz, Is there any complexity in rendering dynamically generated matrix
total columns in CSV format? I have been having this problem that when I
export my reports to CSV, if a matrix in the report has column groupings as
well as dynamic total columns, these total columns don't generate in CSV
version. I was thinking of writing my own CSV renderer but then I thought
there's probably a complexity into that, otherwise the Microsoft CSV renderer
would do it. Is that right? Or do you think CSV rendere just wasn't intended
to render dynamic columns in a matrix?
