This is sort of an ASP/HTML-ish question, but all help is gladly accepted.
We're building some pretty complex reports that have 20-30 parameters (most of them dates with min/max values). When using the HTML report viewer to view the report, we get a page that prompts for parameters (I'll call it the "Parameter Prompt Page"), which is fine. When we use this viewer to look at simple reports that only have 2 to 5 parameters, everything works perfectly. We press the "OK" button after filling out the Parameter Prompt Page, and the report shows up fine.
However, when we have 20 or 30 parameters, we start getting problems. After filling out the Parameter Prompt Page and pressing "OK", we get a web server error message that says "The data being processed is over the allowed limit". I looked this up and Microsoft has a document saying that the IIS server can only process around 110k worth of data before you need to do some special parsing to get it to work. This is documented here:
So I was thinking - well WHAT is so big that it's passing over 110k worth of data? So I loaded up the Parameter Prompt Page and went to View Source in Internet Explorer, and there's an <INPUT> field that is HUUUUGE! The data is some sort of encoded XML data.
Does anyone know what to do in this situation?
It seems like there are other problems, too. When trying to print or export a working report, I get errors that say "webReport.dll error 8000ffff Catastrophic failure".
When I'm on page 1 of a report, and I click on Next page, it skips to page 3. It's all really weird.
