We need your feedback, because we are considering changes in the release approach for Telerik UI for ASP.NET MVC. Please provide your feedback in the comments section below:


1. Is it hard to understand the version numbers of our releases? If yes, what makes them hard to understand them?

2. Would semantic versioning (SemVer) of our releases make it easier to understand our version numbers and what's behind them?

3. If we go with SemVer, we might need to start with version 3000.0.0 as we currently use 2022.x.x. Please share your thoughts about this approach and ideas for what number versioning would work best for you.

I know, it's a big leap but I was assigned this old application. Obviously, a lot of things have changed.

currently we are using:

bundles.Add(new ScriptBundle("~/bundles/kendo").Include(
string.Format("~/Scripts/kendo/{0}/jszip.min.js", KendoVersion),
string.Format("~/Scripts/kendo/{0}/kendo.all.min.js", KendoVersion),
string.Format("~/Scripts/kendo/{0}/kendo.aspnetmvc.min.js", KendoVersion)));

and

bundles.Add(new StyleBundle(string.Format("~/Content/kendo/{0}/css", KendoVersion)).Include(
string.Format("~/Content/kendo/{0}/kendo.common-bootstrap.min.css", KendoVersion),
string.Format("~/Content/kendo/{0}/kendo.custom.css", KendoVersion)))

 

I noticed none of the Content files are around anymore, or the jszip.min.js

Are there new files to replace these with?

I assume, even if there are, there will be code changes involved. correct?

I started out trying to update Bootstrap to the latest, but I don't think the 2017 version of kendo was playing well with it.

Thanks in advance.

As the title states, I have a legacy monolith that must be revived.

I need a few features, especially on the grid, and decided to upgrade Telerik. After a bit of struggle, I managed to run the application but the Telerik controls are by default very small compared to before and the new Size property doesn't seem to be doing much:

Before:

Now:

As it can be seen, the grid shrunk. I do not have a lot of custom CSS on this site but the baseline theme was Start Bootstrap v2 (Start Bootstrap - SB Admin 2 Bootstrap Admin Theme (http://startbootstrap.com)). Not sure if the original theme can still be found.

Hello,

We developed a widget in an empty ASP.NET MVC project with the last Kendo UI for ASP.NET MVC trial version. It works !

Now, we would like to use this widget in a Sitefinity 14.4 project version but we have an error saying that the assembly Kendo.Mvc 2024.4.1112.462 is using System.Web.Mvc 5.3.0.0 but the referenced assembly is 5.2.7.0 version in Sitefinity project.

Is there any way to download an older Kendo UI for ASP.NET MVC version using System.Web.Mvc 5.2.7.0 ?
How can we use a trial version before buying the component bundle ?

We tried with the nuget server but the trial version is only available in the last version.

 

Thank you for your help.

Dear Forum,

please help me. So i want to upgrade an old Kendo MVC application, Kendo version 2016.2.504 MVC. I downloaded the newest 2024.4.1112.Trial before i pay the new. I want to see what is working and what is not working. After the updating (Kendo.Mvc.dll) and the static JS and CSS comes this error, when i started the software the error comes the CSHTML side:

System.NullReferenceException: 'Object reference not set to an instance of an object.'

at Kendo.Mvc.Licensing.GetLicenseMessage()
   at Kendo.Mvc.UI.WidgetBase.WriteTrialMessage(HtmlTextWriter writer)
   at Kendo.Mvc.UI.WidgetBase.ToHtmlString()
   at System.Web.WebPages.WebPageBase.Write(Object value)

Why? What can I do with this error? How to find the right solution. I tested this newest version of Kendo.MVC.dll and JS and CSS with a new empty ASP MVC 4.8 project and working.

I am trying to upgrade a .NET 4.5 project using the Upgrade Wizard.  However, when I attempt to use the wizard I am getting a message saying "No distribution available for your project" and there aren't any versions listed in the dropdown.  

I downloaded the ASP.NET MCV 2024.4.1112.  Am I missing something?

I have attached a photo of the message I am receiving.

Hi!
I am upgrading my .NET 4.8.1 MVC project from 2013 to 2024.
However, I am struggling to do  the following:
1) In old setup (2013), there were .css files which were referenced in the Layout file.
Example: "https://da7xgjtj801h2.cloudfront.net/2014.3.1119/styles/kendo.silver.min.css"

After upgrading to 2024 (via Telerik extension), I cannot find a theme with the same name locally and I cannot use the same CDN link (with modified package version of course).

I found the following info: CDN Info but was not able to follow through and my styles are still not applied.

Here are my original CDN links that need to be updated to 2024.3.1015
https://da7xgjtj801h2.cloudfront.net/2014.3.1119/styles/kendo.common.min.css - Edit: I have managed to find a link for this (or similar version) on Kendo Dojo repo

https://da7xgjtj801h2.cloudfront.net/2014.3.1119/styles/kendo.rtl.min.css - Edit: I have managed to find a link for this (or similar version) on Kendo Dojo repo

https://da7xgjtj801h2.cloudfront.net/2014.3.1119/styles/kendo.silver.min.css - Have not managed to find this (please help)

https://da7xgjtj801h2.cloudfront.net/2014.3.1119/styles/kendo.dataviz.silver.min.css - Have not managed to find this (please help)

Above those, I included the licence snippet:

   <script src="@Html.Raw("https://unpkg.com/@progress/kendo-licensing/dist/index.js")"></script>
   <script>KendoLicensing.setScriptKey('myLicence');</script>

 

How do I fix my links? Any help is greatly appreciated.

Thanks!
