DataGridView Design alternatives

I have many tables that are 'lookup' tables and want to provide a way
for users to Add/Update rows to them.

I will present the data in a datagridview, using a collection of objects
connected to a binding source. The logic for validating and saving is
contained within the object.

I am struggling with trying to decide which way to allow users to
Add/Edit data:

1) directly in the datagridview.

2) in a panel on the same form as the DGV. DGV will be read only. as a
row is entered, the data will be displayed in textboxes, comboboxs, etc
in a panel below the datagridview

3) in a separate form. As a row is selected for editing, it will be
passed to a separate modal form.

thoughts on any of these?

thanx

Jay,

You can better ask your customers. They often have their own ideas about
this related from the background as the are used to it.

That all what you ask is possible is probably because of that.

Just my opinion.
