`Kendo.Mvc.dll` is regularly updated to support the latest ASP.NET MVC 5 version. If you try to use the latest version of Telerik UI for ASP.NET MVC in an ASP.NET MVC 5 application that uses an older version of `System.Web.Mvc`, an exception is thrown saying that the versions of the `System.Web.Mvc` do not match.

## Description
24+
25+
I would like to know if there is a way to deep copy a TreeView node along with all of its children with loadOnDemand set to true?
26+
27+
## Solution
28+
29+
Asynchronously load child nodes in the child data source through [the Node's load() method](https://docs.telerik.com/kendo-ui/api/javascript/data/node/methods/load):
30+
31+
```html

var item = dataItem.toJSON();

Subscribe to the TreeView's dataBound event and [expand()](https://docs.telerik.com/kendo-ui/api/javascript/ui/treeview/methods/expand) all of the currently loaded nodes:
30+
31+
```html

46+
options.ProductID
47+

48+

78+

dataBound: function(e){
100+
if (e.node) {
101+
this.expand(e.node.find('.k-item'));
102+
