Column PatientNo does not allow nulls - help

I am trying to add records to a table using a windows form created in vb with
a dataset object. I have dragged and dropped the fields I want onto my form.
A BindingNavigator is created and am trying to add a new record. I click the
add button, fill out the necessary fields and attempt to update the record.
get the above error.

The PatientNo field is a seeded identity field that is indexed in the table
and therefore can not be null. I understand that.......... When I add a new
record directly to the database no problem, not using my program, the
PatientNo field is incremented and seeded correctly.

However when I try to update the record using the program the first line
below generates the does not allow null error.

Private Sub PatientBindingNavigatorSaveItem_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles




End Sub

How do I stop the error from occuring and get my database updated?

A little frustrating to say the least.


Thanks, Jim
