Setting default values in bound controls on a form

The fields are bound to a binding source which has an AddingNew event where you can do something like:

e.NewObject = <something>.  The something however needs something of the same type or else you get an error message of "Objects added to a BindingSource's list must all be of the same type".  I assume this is a DataRowView except I don't don't know how to create one in this context.

One way is to use code like this: DataRowView rowView = dsNorthwind.Customer.DefaultView[0] but this implies the row is already in the underlying dataset except it isn't because it's a new row in the process of being added.

What I wound up with is:

bool _AddingNew = false;
private void bsNotes_AddingNew(object sender, AddingNewEventArgs e)
{
  _AddingNew = true;
}

private void bsNotes_CurrentChanged(object sender, EventArgs e)
{
  if (_AddingNew)
  {
    _AddingNew = false;

    if (bsNotes.Count == 1)
    {
      ((DataRowView)bsNotes.Current).Row["NoteDate"] = DateTime.Now;
    }
    else
    {
      NoteDate.EditValue = DateTime.Now;
    }
  }
}
