DataSource
configurationThe data source of the Grid holds the items that will be rendered inside the widget. An item 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 will initialize a new kendo.data.DataSource instance by using that value as a data source configuration.
If the dataSource option is an existing kendo.data.DataSource instance the widget will use that instance and will not initialize a new one.
For live demos and more complex configurations, refer to the article on binding the Grid to local data and binding the Grid to remote data.
