dataSource kendo.data.HierarchicalDataSource

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

<input id="dropdowntree"/>
<script>
$("#dropdowntree").kendoDropDownTree({
  dataSource: [
    { name: "Apples" },
    { name: "Oranges" }
  ],
  dataTextField: "name",
  dataValueField: "name"
});
var dropdowntree = $("#dropdowntree").data("kendoDropDownTree");
dropdowntree.dataSource.add({ name: "Appricot" });
dropdowntree.search("A");
</script>
