Hello Radouane,
I noticed that in your stackoverflow thread, you mentioned that you are using the TreeView widget in an Angular 2 app. Can you confirm this?
If this is the case, keep in mind that the
Kendo UI Professional (or Kendo UI for jQuery) integration with Angular 2 is not officially supported as stated in the following article:
There is a separate
Kendo UI suite for Angular 2, which is build on top of the Angular 2 Framework and provides a fresh native implementation of the widgets.
Currently, the TreeView component is not yet implemented, but it is considered as a long-term goal which is yet to be explored. You can find more information in the
Roadmap for Kendo UI for Angular.
In case you are using the jQuery suite in a non Angular 2 scenario, may I ask you to provide an isolated working example in the
Dojo sandbox, so that we can pin down the issue and provide you with further assistance?
I am looking forward to hearing from you.
Regards,
Dimitar
