DataSource
configurationThe data source of the widget which is used render ListBox items. Can be a JavaScript object which represents a valid data source configuration, a JavaScript array, or an existing kendo.data.DataSource instance.
If the dataSource option is set to a JavaScript object or array, the widget initializes a new kendo.data.DataSource instance by using that value as the data source configuration.
If the dataSource option is an existing kendo.data.DataSource instance, the widget uses that instance and does not initialize a new one.
