I have a web page coded in c# and asp.net. On that page I have a
datagrid with and edit button link. I can click the edit button and
it selects the corret record, and even cancels correctly. However
when I enter some new information and click the update link, it
returns the old information and not the newly entered information.
Could you please take a look at the following code and see if you
could help? Thanks, and here is the code:
