Delete record from Dataset - changes not pushed to dbase

Hi,

I have a WPF form bound to a DataSet.

I've added button to delete the active record and used the code below :

if (jobsViewSource.View.CurrentPosition >=0)          
{                
aPIntegrationDataSet.Jobs.Rows.RemoveAt(jobsViewSource.View.CurrentPosition);                
aPIntegrationDataSetJobsTableAdapter.Update(aPIntegrationDataSet.Jobs);                
aPIntegrationDataSet.Jobs.AcceptChanges();                
jobsViewSource.View.MoveCurrentToLast();          
}

The record does get removed from the dataset but when I close and reopen the form the record reappears.

I thought that running update on the table adapter would push this deletion back to the database.

Any ideas where I'm going wrong?
