CSS Issues After Upgrading to Version 2024.4.1112

[n/a]

Hello

I am currently using a purchased Kendo UI license. I plan to replace my existing Kendo UI with the latest jQuery version 2024.4.1112. Before making the change, I do not know the version I was previously using.

When I check the CSS file, I see the following comment: 

/**

Since someone else developed this project, I am not sure which version was used, and if I try to update to the latest version, there are issues with the CSS.

Currently, my license allows me to download the following versions:
2015.2.624
2022.2.510
2022.2.621
2022.2.802
2022.3.913
2022.3.1109
2023.1.117
2023.1.314
2023.1.425
2024.2.514
2024.3.806
2024.3.1015
2024.4.1112

If I need to upgrade step by step to use the latest version, I am unsure what to do since I cannot find version 2017.2.621. Can you help me figure out how to use the newest version?

Hello,

There are multiple changes in the Kendo suite introduced in the versions between 2017 and the latest 2024.4.1112. 

From the provided information I am not sure if you are using the SASS or LESS based themes. An important change related to the themes is that the LESS themes have been deprecated and are no longer available. You can read more about the decision behind the change and how to migrate to SASS themes in the links below:

- https://docs.telerik.com/kendo-ui/styles-and-layout/less-themes/less-themes-migration 

- https://www.telerik.com/blogs/future-plans-telerik-kendo-ui-less-themes

Another large change is the updated rendering of the components which was ongoing effort, thus there are changes introduced in multiple releases. I would reccomend taking a look at the article linked below regarding the changes:

- https://docs.telerik.com/kendo-ui/styles-and-layout/components-rendering-overview.

I would also suggest taking a look at the breaking changes section that describes the breaking or important changes introduced in the years. 

- https://docs.telerik.com/kendo-ui/backwards-compatibility 

To check which Kendo version is currently used in the project you can open the browser console and type kendo.version.

When you upgrade to the latest Kendo version in case you have any issues, please send us more information about the exact issue and the component you are using, as well as its configuration. This will help us to be aware of the exact scenario and provide you appropriate assistance to resolve the issue.

I remain at your disposal should you have any questions.
