ReportViewer with fixed length text file

[Mic]

Hi,
I just started using Visual Web Developer Express 2005.

I need to print a dataset that is populated from a fixed length text
file. No problem with this part.

So I am trying to use a ReportViewer to do the printing.
I searched and searched and I only saw the ReportViewer used with an
ObjectDataSource bound to a "Website data source" defined at design
time for the report.

I cannot see how to use a text file data source to work in conjunction
with the ObjectDataSource (or anything that could print my dataset).

Thanks
