All styling broken after upgrade to 2023.1.314

[Kevin F]

All the styling is broken, using bootstrap.  I noticed a massive change in the files in Content/kendo/2023.1.314 (i.e. none of the previous files I had linked to actually exist anymore).  I upgraded from 2023.1.117.  Do I use bootstrap-4.css or bootstrap-main.css or what?

I ran the upgrade wizard and there was nothing about such massive changes. 

Where's the documentation on these changes?  Happy to read up but I couldn't find anything?

This is disgraceful for a minor upgrade to break/change everything so drastically.

Appreciate the detailed info.  Unfortunately, I fall into the category of heavily modifying the material LESS theme so this release is a going to require a ton of work for me.  However, it looks like the new SASS themes do easily handle a good portion of the customization I have been doing in past years (size, rounded corners, etc.) so it "might" not be that bad.

Hi John,

Thank you for the kind words. I am glad to hear that the new changes are handling some of the customizations.

If further assistance or information is needed, do not hesitate to contact me and the team.

Best Regards,

Same issue here after upgrading from 2022.3.1109.  For years the CSS theme files were included in the source code but appear to have been removed as of this version.  My guess would be this is part of the move to the CDN. 

ASP.NET Core Using CDN - Telerik UI for ASP.NET Core

I need to include 2 styles, kendo.common-material.min.css and kendo.material.min.css.

As far as I could guess that lead me to this url but it's not a complete solution and my styles are completely broken.  Some upgraded documentation is needed for sure.

https://kendo.cdn.telerik.com/themes/6.2.0/material/material-main.css

Are they forcing CDN use? I like to avoid that whenever possible.

[John]

Me as well.  I don't think they are forcing it but they are encouraging it.

I want to know where all the old style sheets went, and where the docs are explaining why the huge difference between the last two releases!
