I want to do this: build a list of emails to be sent to customers based on a query on db by a cron job. I don´t want to send the emails automatically, I want a human confirmation step in between.
That means I want to show a grid or a repeating list of controls that, per line, show:
checkbox, name, date1, date2, etc
This list can be n long and when user has checked/unchecked boxes, a buttonclick will start sending emails.
So the question is: how do I build such a list when n is unknown beforehand (at design time of form).?
