Forms Data Controls :: Using DataBinding To Populate Data?

I have a GridView that I'm using DataBinding to populate data. I'm binding to a List<Widget> in the Click event of a button. Once clicked, I set the .DataSource to the List<Widget> and call DataBind(). It correctly binds the data. I also use ASP.NET's built-in function to have delete buttons on all rows.

Here's my issue. When I get the List<Widget> it actually gets the data from a database. At times, I want to delete just one or two Widgets FROM THE VIEW and not actually delete it from the database. For example, the user fills out the form, clicks the button, and the system returns a List<Widget>. Well, there are two widgets in the list that the user doesn't want to ship with the order, so they click the "delete" button for the first row and then would click the "delete" button for the next row. So if I had 5 Widgets returned, and I want to delete 2 of them, the GridView would have 3 remaining Widgets. How can I delete the rows without rebinding? Because if I rebind, it will get all the Widgets again. With my BLL, I can't just select the 3 Widgets, it will always return the 5 widgets, and the user will "delete" the Widgets that are not supposed to ship with the order. I suppose I'm asking if this is possible to delete the rows without having to store the information to the Session object or other way to save state. Can I do something like GridView1.Rows[<Index>].Delete()?
