An old friend of mine, Joe Shook, laughingly said, you should read what other people write too once in a while. Of course, he was right and naturally I do. I read almost everything I can get in my hands including technical books, blogs, and articles because I am surprised by the number of things I haven't mastered or that I still don't have a best practices sort of solution for. Thankfully I am still willing to stay up to 11 or 12 o'clockused to be until the next morningworking out the details of what I don't know until I am happy with an answer.
The difference is that Bind is a two-way bind (read and write) and Eval is a one way bind (read-only) from the Data Source. Item Updating Dim control As Drop Down List = Form View1. If you use Eval then remember that the Drop Down List is in a template of the Form View, so you have to get the actual Drop Down List by calling Find Control and setting the updated value to the e.

The Form View is a binding control like the Grid View, except where the Grid View shows multiple rows of data and the Form View shows one record at a time in a form layout.The edit template contains a Drop Down List and the population, binding, and updating is all handled declaratively. After you complete the data source wizard the Form View will have controls added to it for the Item Template, Edit Item Template, and Insert Item Template.
