I am working on an apps. that basically creates and maintains file system. User can create, update, delete, and print the file. When user creates a new file the back end creates new master record. I dont know how to deliver that new id back to the client in order to save details of the new file with new id. Can you tell me what approach should I take?

When the DataSource issues an "add" DSRequest, return the new record-as-saved. In your case (ASP backend returning XML responses), send back XML for the saved record that matches the format you use when fetching records, and containing the id of the new record.
