Hi,
We generally don't intend to introduce API which will work without the DataSource. The latter is a very important part of Kendo UI and all data access and data operations are performed through it. Inserting records is supported via the insert/add/ methods of the datasource. You can use the data() method to replace all data.
grid.dataSource.data([object, object])
