The treeview events demo has event handlers such as the following:
function onCheck(e) {
kendoConsole.log("Checkbox changed :: " + this.text(e.node));
//??????? do something useful ?????
}
But how would I do something useful, like get ID, checked status (checked or unchecked), or other fields of the item checked?
If the data source has model with fields "Id", "name", "something", how would I get those values?

Hello Scott,
In order to get the data item associated with the node DOM element you can use the dataItem method of the Kendo UI TreeView. Once you have access to the data item object you can access the model fields and etc.
Also checked field of the data item returns the state of the check box element for the node.

Something like this?
function onPrivilegeCheck(e) {
var treeView = $("#myTreeView").data("kendoTreeView"); // how to get treeview object, if named "myTreeView"
var nodeData = treeView.dataItem(e.node); // get an object representing the data of the node that was checked(triggering this event)
var checkedStatus = nodeData.checked; // get the checked status of that node
//do something useful here
}
Hello Scott,
Yes indeed and the onPrivilegeCheck function should be handler for the check event of the Kendo UI TreeView.
