SQL 2014 and VB 2015

I have a windows form that is connected to a SQL 2014 dataset. I just recently upsized the form from a  local access table to a SQL server table. OH BOY!

A left over issue that I'm having is that I have a PK set on field called 'Record_ID' that is seeded from the server. The update command is throwing an error that the value is null. (that's my problem I think) The identical code worked fine for Access by SQL is wielding amighty fist I think (which is why I did it)

I'm using this code.
Company_ContactsBindingSource.EndEdit()
Company_ContactsTableAdapter1.Update(Me.DB_104222_crmDataSet.Company_Contacts)

I'm left wondering if I can insert new and call an update to force the field to update and assign a value? The  continue to add any information and update again?

Ideas?

make the field identity, that should do it.

I set it to identity but...

When I call the update I get a message back saying that "the field doesn't allow nulls"; which is true because it is an identity.

When I call add new I'm thinking that I need to update that record to pull that value? I think that but I'm not sure how to do that.

Oh boy again!

I mentioned that I moved the database from Access to SQL . Everything went fairly well except for this problem.

It turns out that even though the message sent back from .net said that the 'identity value' cannot be null, that message had nothing to do with the problem. It turns out that 7 fields in this table had the allow null checkbox value turned off. Sql Server didn't like that values being null so it in turn pulled 'identity value' out of it's hat and gave me that message.

Epitome of the 'red herring'. In the end got it figured out and I'm adding this up to a gotcha and 'served me right' for not developing the app in SQL to begin with!
