.Net - Best practice for element id's in repeating page sections

[Johnnie]

I'm not sure how to boil this question down into a sensible single-line title. I'm also new to .Net.I want to build a web-page version of an invoice, but I want each page of the invoice to flow down the page, not be paginated. The header of each section will be the same, but the line items and the footer will be different.I've done this before by writing html to a stringbuilder and then outputting it to a literal control, but I think there must be a better way. I'm just having a hard time conceptualizing how to do something like this with server controls because of the fact that the ID's need to be unique. Can someone point me in the right direction here?Thanks!
