Passing parameters from a dataset

[User]

I have a problem with wanting to pass parameters in a dataset from one page to another. For example, I have a stored procedure which returns a dataset. Some of these items are bound to web controls on page1. If I wanted to pass one of the bound items from page1 to page2 I could use "request.querystring" on page2. But I also want to send a data item from the dataset which is NOT bound on page1. Request.querystring will not see it. In old ASP I would create a Hidden field on page1 and bind it there. So what is the best way to accomplish this in asp.net
