title: Do I Need to Call .AcceptChanges() before .Update() After a delete Operation
body: <p>Hello I'm making a small database application with MS Access database. I add to database from a textbox and delete from a database using a combobox and showing the database in datagridview adding seems to work fine except for autoincrement not showing before a restart and i cant delete because when i call update after deletion it gives me a DBConcurrencyException i tried to add acceptchanges before update and that is not gave any error but the changes didn't saved to database.</p>
  
  <p>Here is my two questions</p>
  
  <ul>
  <li><p>How to make autoincrement show without restarting application.(this is not so important i can hide ID column)</p></li>
  <li><p>And most importantly how to make deletes work.</p></li>
  </ul>
  
  <p>additionally i use OleDbCommandBuilder for update methods</p>
