Sorry to take so long to get back to you. The scenario is that the details view is the 'master' record (for example customer) and the grid view shows the detail records (e.g. customer orders). Like this:
Customer: My Customer
Address: 23 the street, Town, County.
Tel: 01234 567890
Order No Product Cost
1 prod1 Â£20
2 Prod2 Â£22
I have seen a fair few examples the other way around, where clicking on the order (shown in a gridview at top of form) would show all details of the order.
Thanks for your post. Hope you can follow-up.
