I am trying to use a gridview for companies, edit the entries based on a list coming from a table in SQL Server.
in this example, I have a gridview interfacing a company table. I want the user to be able to select a service area from a uniform list (sql server again) and have those values update the EntityID in the Company Table.
If I use a simple text box which is the default when you add the editing functionality - it binds without any problem. When I change it to the dropdown list, it does not seem to bind.
I'm kind of new to asp pages so forgive the elementary nature of the question.
