Formview buttons - Am i supposed to have to program them?

I have a form view without a gridview. I've searched relentlessly on the net to find an example that does not use a gridview..it seems like these two go hand in hand...

I have a dropdownlist with a list of customer names. However, index position 0 is "---New Customer---"

So depending on what is selected in this combo box, when one clicks a select button it displays the proper formview mode...Everything works fine..

When I select a customer and click select, it bring up edit mode.. this is fine.. I make a change and hit update and nothing happens.. however, the events do fire but as I understand it, these buttong are pre programmed to do their jobs... right?

I also have this problem inserting a new customer with formview... the insert button does nothing. however the cancel buttons do work..

So my question is, do I need to program these buttons to make them work, or do I have parameters wrong or something?
