Acessing reports services 2005 using url with parameters can be tricky sometimes because we have to construct the URL to the page with the parameters we want, my advice is to make step by step,
Ok what i did here
i call the reports and use some parameter to make the filter with the name:
this fields will be defined in the report by @ "where [field]=@id and [field]=@type and [field]=@typename
and if you want to export directly to a PDF file you will need to add the tag in the url
Ok is done easy and fast way to export reports to pdf, and you dont need to preeview report...
