Hi all,

I am glad to announce that the PanelBar component now exposes 3 new preventable events in v6.6.0 of the Layout package:

• select
• expand
• collapse

The existing stateChange events behavior is unchanged and cannot be prevented.

Hi Daniel,

I understand your frustration from the missing desired functionality. In general we are monitoring the demand for each logged feature request and based on multiple factors such as votes, business value, resources and others we decide which feature to be prioritized.

In general Kendo UI for Angular was released during 2016 after the release of the Angular 2+ framework. Thus I am not sure which product you have used at this point. It could be the Kendo UI for jQuery PanelBar. If that is the case and you would like to use this widget inside an Angular 2+ project please see the following article which demonstrates how to integrate any Kendo UI for jQuery widget inside an Angular 2+ application:

Hi Charu,

At this point there isn't a built in feature that allows to achieve the requirement. What could be done as a workaround is to manually keep an array of items in sync with the state of the PanelBar. That will allow to check the value of the emitted (stateChange) event and re-render the PanelBar with the desired items array. Please see the following example where the expansion of the "foo" item is prevented using such approach:

We will further monitor the demand for this feature request and eventually add it as a built - in feature to our future development plans.

Hi,

Thank you for sharing your idea. Indeed, this would be a nice enhancement to the built-in functionality of the PanelBar component. We will track this thread to estimate the customer demand, and prioritize accordingly when updating our tasks list.
