I would like to call a JavaScript function when a nodes' checkbox is clicked so that I can update anther control on screen. There is not a "OnChecked" event, so is it possible ?

Any help appreciated,
John

Hello John,


Indeed there is no built in onChecked event. Since the checked state of the items is stored in the dataSource, you could bind to it's change event to handle the checking (unchecking) of the items.
E.g.
$(function () {
    var treeview = $("#treeview").data("kendoTreeView");
    treeview.dataSource.bind("change", function (e) {
        if (e.field == "checked") {
            //an item was checked/unchecked
        }
    });
});

I hope this information helps.
