Passing only 'selected' records to next page

I have a web page that pulls all of the expense records that have NOT yet been invoiced for a given project and lists them in a table. The table contains a checkbox which, when selected, I would like to pass all of the data to the next page for that particular expense entry. I need to pass Expense_ID, and Expense_Date, Quantity, Description and Unit Cost (these 2 from a related table) for each record with a check box. I'm using .asp Can I ( should I ) do it like that (even if it's possible) or should I create an array on the following page and zoom through the expense table again?

You could just load all the data into a DataSet or DataTable and then store it in a session object. The session object will be accessible on the next page, just cast it back into the proper object type when you need it. Example in C#: CODE //DataSet contains data to be passed to another page DataSet ds = New DataSet(); //store the DataSet in a Session object Session["myDataSet"] = ds; //to get the data back on the next page, just cast it DataSet ds1 = (DataSet)Session["myDataSet"];

I tried this code simply as a test: DataSet ds = New DataSet(); but got an error: Compiler Error Message: BC30451: Name 'DataSet' is not declared. Care to give me a bit more guidance? Thanks
