## Warning
2017-02-19 17:02:58 +08:00
According the [standard ](http://facebook.github.io/react/docs/lists-and-keys.html#keys ) of React, the key should always be supplied directly to the elements in the array. In Transfer, the keys should be set on the elements included in `dataSource` array. By default, `key` property is used as an unique identifier.
2016-08-03 10:10:13 +08:00
2016-08-04 09:33:04 +08:00
If there's no `key` in your data, you should use `rowKey` to specify the key that will be used for uniquely identify each element.
2017-10-25 10:25:44 +08:00
2016-08-03 10:10:13 +08:00
```jsx
// eg. your primary key is `uid`
return < Transfer rowKey = {record = > record.uid} />;
