Pass parameter from ASP.Net page to Cognos to create report

Hi Experts,

I have an ASP.NET webpage with a gridview in which I have placed a Hyperlink field whose value is my Order ID (the key to my SQL table). I have a Cognos report built with a prompt page where in you can choose the Order ID and it will give you details for that Order. The gridview shows cursory information for each unprocessed Order in the SQL table. My charge is this: to put an HTML Link in the GridView so that the person using that webpage can click on the Order ID link and produce a detailed report for that Order. I almost have it working except when I click on the HTML link it takes me to the Prompt page and I have to select the Order ID again from the Prompt page in order to produce the report for that Order. Is there any way to send a parameter with the Cognos report request so that it knows which Order I want to produce the report for, rather than having to re-select the Order ID on the Prompt page?

I have pasted my .aspx page code.

You can specify the prompt values on the URL to the report.  This document describes all the fun things you can do with URL's with Cognos:


This is from the section you're interested in:
Passing Prompt Answers
To ignore the prompt page, the parameter run.prompt must be set to false. Otherwise, the
prompt page will appear with your prompt answer as the highlighted selection.

The information you provided is helpful. I was able to suppress the prompt page; the only trouble I'm having now is getting it to recognize the gridview field, Order_ID as containing the prompt value. If I  hard-code the Order ID like  p_Order_ID=165 the report will successfully run, but I'm looking for a way for it to take the Order ID associated with the selected line on the Gridview as the prompt value and create the report from that. Whenever I do something like p_Order_ID=Order_ID I get an error saying "Invalid format for numeric prompt 'Order_ID'." i.e. Its not resolving to the value of Order_ID in the gridview. Any ideas on how to make it do this?
