storing array list in database.

Question

Hello,

I have a college project to do on billing system.

I have displayed dynamic data from texboxes in datagridview using arraylist.

 

All i wanted is to store datagridview values as a list in database or entire invoice details as one file in xml file as database.

 

if, i am working with xml file then i wanted to store invoice items dynamically with single id which will be easy to fetch and manupulate.

 

So can you help with any demo sample?.
