After reading through Chapter 6, I don't see Vince used any standard ASP.NET controls (Gridview, drop-drown list). Is there a reason to use a custom girdview instead of a standard one?

If I would like to use a standard gridview control and drop-down list, how would I bind/submit data using Datacontext and entity objects?

Let's say I have a gridview. I want to put a checkbox for Approval and Reject for each entry. After several unsuccefull tries, I could not make the standard ASP.NET gridview working. How can I acomplish this task with using the custom grid view described in the textbook?

Please help me or give me some hints. Thank you very much!

page 104 of the book (The CustomGridView Control) gives a pretty good explanation for why he's doing it this way.
