dataSourcekendo.data.DataSource
The data source of the widget. Configured via the dataSource option.
Changes of the data source will be reflected in the widget.
Important: Assigning a new data source would have no effect. Use the setDataSource method instead.
Example - add a data item to the data source
<select id="multiselect" multiple="multiple"></select>
<script>
$("#multiselect").kendoMultiSelect({
  dataSource: [
    { name: "Apples" },
    { name: "Oranges" }
  ],
  dataTextField: "name",
  dataValueField: "name"
});
var multiselect = $("#multiselect").data("kendoMultiSelect");
multiselect.dataSource.add({ name: "Appricot" });
multiselect.search("A");
