Greetings.

I have a database table of products. A record can be either a parent or a child. I retrieve a parent record and then get the children based on if a record has the  Parent Column that matches the  ID of the parent record  I just retrieved.

I have a grid in my view.ascx below. How do I do the databind for this grid? Say I have 2 parent products and 10 child products for each parent.

Thanks!

Chris
