                                            .Minimize()
                                            .Maximize()
                                            .Close()
                                            ).Visible(false)
                                            .Resizable()

Hi Monalisa,

Changing the product's version with one that is 3 years newer could result in the introduction of breaking changes inside the components and the way they interact with each other. 

To be able to help you with the current case, I will need more details about the scenario on which you are working. What was the previous correct behavior and what is the current one? Can you isolate the issue in a runnable example and send me this example so I can test it locally and provide more relevant feedback? 

Last but not least, after updating the DLL file, did you also upgrade the Kendo UI CSS and JS files?

Hi Petar,

Thank you for your reply,

Yes after changing new version of kendo ddl i updated JS and css files also.

It was working fine with v2015.9.390.545

Please go through attached file for more details. Sector tree view should displayed like location treeview.

I will be great to get a solution asap. Thanks

Hi Monalisa,

To be able to help you, we will need a runnable example in which the reported behavior can be replicated. Otherwise, we cannot identify the source of the issue. 

Create a runnable example in which we can reproduce the issue with the TreeView and send it to us.  Thus we can further investigate why TreeView is disabled. If you don't want to publicly share your code, you can submit a new support ticket and we will handle it according to the response time of your support plan.
