如何在TcxGrid (TcxGridDBTableView)中获取相邻记录的ID值

var
  GridTableView: TcxGridDBTableView;
  DataController: TcxCustomDataController;
  FocusedRecordIndex, RecordCount: Integer;
  PrevRecordID, NextRecordID: Integer;
begin
  GridTableView := TcxGridDBTableView(Grid1.FocusedView);
  DataController := GridTableView.DataController;

  FocusedRecordIndex := DataController.FocusedRecordIndex;
  RecordCount := DataController.RecordCount;

  if (FocusedRecordIndex >= 0) and (FocusedRecordIndex < RecordCount) then
  begin
    PrevRecordID := DataController.Values[FocusedRecordIndex - 1, 'ID'];
    NextRecordID := DataController.Values[FocusedRecordIndex + 1, 'ID'];

    // 使用获取到的相邻记录的ID值进行后续操作
    // ...
  end;
end;
