Recently upgraded from kendo 2016 to 2020, I no longer able to see the class k-invalid-msg in content/kendo. If its removed in latest kendo what is the alternate?

Hi, Sowjanya,
Thank you for your question.

The k-invalid-msg class is still around. However as referred in this article on backward compatibility, a breaking change concerning the Validator was implemented recently. If the  workaround suggested there doesn't help, I would ask you to share some more details about your issue. A runnable sample would be most appreciated.

Hi Sowjanya,
thank you for providing more information.

From the screenshot you shared I understand that the issue is with your IDE's IntelliSense, is that correct? You can try to host the CSS theme files locally as described in this forum thread: https://www.telerik.com/forums/css-intellisense-not-working

Let me know if this suggestion helps resolve the issue.

Surprisingly I don't find k-invalid-msg in any of the css files in latest kendo. This is the reason it shows the error message that unknown class. Can you help me what am i missing here? 

My upgraded version is Kendo UI v2020.2.513.

Hello, Sowjanya,
thank you for your follow up.

I investigated further and indeed the k-invalid-msg class has been removed. The reason for this is the previously mentioned changes in the Kendo Validator styling. That said, if you have used it as a selector, for example, you can continue using it, though no styling will be applied for it. In the updated Validator we have replaced k-invalid-msg with the more concrete k-form-error and k-form-hint, needed for the updated styling. Should you need further details about the current classes I can suggest inspecting the DOM for complete details on the HTML markup and classes applied after validation.

Hopefully, this clears up the issue.
