We are using KendoUI library for jquery. We upgraded from 2021 to 2025.2.520 version.

After upgrading we are facing issue with multiselect dropdown. Control having change events, after selecting any new value or removing existing values- on-closing of list items popup we are triggering "SelectionChanged" event, so it's taking more time to close the popup and disabling all other controls click event. After closing the popup , we are able to click on other controls.
How to overcome this issue?

Hi Jyothsna, 

I have replied earlier to the support thread on the same topic. I would recommend continuing the conversation in a single thread. For convenience, below you will find my last reply copied:

In order to be able to help, I will need an isolated, runnable example where the issue is demonstrated. From the provided information, I am not sure how we can replicate the issue locally, so we could investigate further. If it is more convenient for you, you could use the Dojo linked here that contains cascading MultiSelects as a starting point - https://dojo.telerik.com/KSaIEVtq

Also, could you please provide more information about the forums where the change is discussed? I could not think of such a change applied to the Multiselect implementation released in the past years that affects the change event in such a manner. 

Looking forward to your reply.

Regards,

Neli
