version 2023.1.314 missing css on cdn

[Chris]

I am getting an error "Sorry, the page you are looking for is currently unavailable." from your CDN loading css example:

https://kendo.cdn.telerik.com/2023.1.314/styles/kendo.bootstrap-v4.min.css

JavaScript works fine though:

https://kendo.cdn.telerik.com/2023.1.314/js/jquery.min.js

Is there a general rule of what cdn url to use?, I did put in a suggestion a while ago which got rejected would be handy if this was added:

    @{
        var version = typeof(Kendo.Mvc.KendoServices).Assembly.GetName().Version;
        string kendoCDN = $"//kendo.cdn.telerik.com/{version.Major}.{version.Minor}.{version.Build}";
    }
    <link href="@Url.Content(kendoCDN + "/styles/kendo.bootstrap-v4.min.css")" rel="stylesheet" type="text/css" />
    <link href="@Url.Content(kendoCDN + "/styles/kendo.common-material.min.css")" rel="stylesheet" />
    <link href="@Url.Content(kendoCDN + "/styles/kendo.rtl.min.css")" rel="stylesheet" />
    <link href="@Url.Content(kendoCDN + "/styles/kendo.material.min.css")" rel="stylesheet" />
    <link href="@Url.Content(kendoCDN + "/styles/kendo.material.mobile.min.css")" rel="stylesheet" />


    <script src="@Url.Content(kendoCDN + "/js/jquery.min.js")"></script>
    <script src="@Url.Content(kendoCDN + "/js/jszip.min.js")"></script>
    <script src="@Url.Content(kendoCDN + "/js/kendo.all.min.js")"></script>
    <script src="@Url.Content(kendoCDN + "/js/kendo.aspnetmvc.min.js")"></script>
    <script src="@Url.Content(kendoCDN + "/js/kendo.timezones.min.js")"></script>

Hi Chris,

As of v 2023.1.314 there has been a change in the structure of the CDN that serves the css files. 

The URLs of the Telerik CDN have the following structure:

• https://kendo.cdn.telerik.com/themes/[THEMEVERSION]/[THEME]/[FILENAME]—The themes folder contains the .css files of the SASS themes for Telerik UI for ASP.NET Core versions after R1 2023 SP1.
• https://kendo.cdn.telerik.com/[VERSION]/styles/[FILENAME]—The styles folder contains the minified .css files (SASS and LESS) for Telerik UI for ASP.NET Core versions before R1 2023 SP1.

The corresponding theme version can be found in the Compatibility section. So, for example, to load the bootstrap-main, bootstrap-4 or default theme the url would be:

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

//bootstrap-4 theme
https://kendo.cdn.telerik.com/themes/6.2.0/bootstrap/bootstrap-4.css

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

For further details refer to the documentation section.

Thanks for providing a response.

I use nuget to update the libraries so it would be really handy to have a quick way of getting the URL without having to now manually lookup the theme number:

@Kendo.Mvc.CDN_URL

Can you consider amending the project url in nuget to a page listing the changes and known issues, so people can make an informed decision and have visibility of breaking changes.

Without this forum I wouldnt know about known issues e.g. https://www.telerik.com/forums/urgent-listview-completely-broken-v2023-1-314#1601851 and unless you know where to look I wouldn't have found this in your help. The CDN 404 page could have linked to a developer help page..

[Aleksandar]

Form the example provided I see the version is obtained from the assembly properties, rather from the NuGet package metadata. As I'm no expert on the matter, I've raised the discussion internally with the corresponding team to investigate appropriate ways to provide additional information on the theme version used, if possible.

As for details on the changes we do provide such information. For example:

• Release History section - you can find details on changes per release version.
• Breaking Changes section - you can find further details, on the breaking changes, if any, for a particular year and release.
  
  
• We have a public Feedback portal that contains details on Feature Requests and Bug reports. If you prefer, you can review the issues in the public GitHub repository as well.

Are you able to update this status from unplanned on this item: https://feedback.telerik.com/aspnet-core-ui/1555011-add-version-number-or-cdn-url-to-assembly so it can be re-considered or should I re-post it?

[Aleksandar]

I'm glad to hear the information provided was helpful.

Unplanned is the correct status of the item - the status means that the item is a valid feature request or bug report, not scheduled for implementation yet. You can find more details on the meaning of the statuses used in the Feedback portal here: https://feedback.telerik.com/aspnet-core-ui/status-info
