private class MyCustomFilterAction : ICustomFilterAction
{
  public bool IsItemPassFilter( object item, string filterText )
  {
    return (string)item == filterText;
  }
}

autoCompleteTextBox.FilterType = StringFilterType.Custom;
autoCompleteTextBox.CustomFilterAction = new MyCustomFilterAction();
