A DataSource is a stateful object, which means that it saves data processing settings and applies them each time data is loaded. All underlying data access logic of a DataSource is isolated in a Store. A Store provides an API for reading and modifying data. Unlike the DataSource, a Store is a stateless object.

, ,
, :
, [
, and ]
. Their presence may cause issues in the widget's operation.If the data source is specified using the dataSource option, use the items option only for reading. Updating data items using the items option may cause unexpected results.
