TreeView React Wrapper doesn't re-render properly

• Bug report

The TreeView React wrapper works fine in the example shown in the docs.

But if the component is re-rendered (because of new props), it doesn't render the new dataSource as it should.

Here's a working example of the buggy behavior: https://stackblitz.com/edit/kendo-ui-treeview-bug

You can workaround it by wrapping the TreeView inside functional component:
https://stackblitz.com/edit/kendo-ui-treeview-bug-xzybve?file=app/main.js
This will ensure that the widget it will be removed and destroyed correctly, and new one will be instantiated.

Keep in mind we expect our pure KendoReact TreeView to be released in January, and we don't have plans to fix issues in the react wrapper of the jQuery TreeView widget.

Oh great, I'll wait for the proper React component then. Please provide an easy way to get the dataSource item in the onChange event.

@eparizzi The item can be retrieved using the select method to get the selected element, and them the dataItem method to get the data:

@simonssspirit Thanks. I couldn't find an easy way to do that.

Anyway to get the parent of the selected element?

UPDATE: Nevermind, I've found how.

I hope this gets clearer when the TreeView is ported as a pure React component. Please work on proper documentation.

Thanks
