loadOnDemand Boolean
(default: true)
Indicates whether the child DataSources should be fetched lazily when parent groups get expanded. Setting this to false causes all child DataSources to be loaded at initialization time.
Note: when initializing the widget from an array (rather than from a HierarchicalDataSource instance), this option defaults to false, rather than true.
Example - force lazy loading of sublevels
<div id="treeview"></div>
<script>
$("#treeview").kendoTreeView({
loadOnDemand: true,
dataSource: [
{ text: "foo", items: [
{ text: "bar" }
] }
]
});
</script>
