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.

Example - force lazy loading of sublevels

<ul id="panelbar"></ul> <script> $("#panelbar").kendoPanelBar({ loadOnDemand: true, dataSource: [ { text: "foo", items: [ { text: "bar" } ] } ] }); </script>
