17 Nov to 24 Nov 2025: highlights of the new online resources that we published last week.

Article: https://www.telerik.com/aspnet-mvc/documentation/knowledge-base/chat-ai-integration
Summary: This article shows you how to integrate the Telerik UI for ASP.NET MVC Chat component with an LLM (OpenAI or Azure OpenAI) by posting user messages to a server-side controller that proxies the Chat Completions API and returns AI replies in the Chat message format. You’ll set up the MVC wrapper and client-side transport, preserve conversation context, map system/user/assistant roles, secure API keys on the server, and handle errors so the AI responses render correctly in the Chat UI.

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 have multiple autocomplete boxes and they all filter through the same AJAX datasource.  I want to somehow pass the ID of the specific box to the AdditionalData javascript function so that I don't have to write like five different JavaScript functions with pretty much the same logic.  I didn't see anything in the documentation and passing "e" in the AdditionalData function just passes the filter.

<strong>To:</strong>  Html.Kendo().AutoComplete().Name("ToAddress")
                    .DataTextField("Email")
                    .Separator(";").MinLength(4).Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(r =>
                        {
                            r.Action("SearchAD", "Home").Data("AdditionalData");
                        })
                        .ServerFiltering(true);
                    }))

<strong>CC:</strong>  Html.Kendo().AutoComplete().Name("ccAddress")
                    .DataTextField("Email")
                    .Separator(";").MinLength(4).Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(r =>
                        {
                            r.Action("SearchAD", "Home").Data("AdditionalData");
                        })
                        .ServerFiltering(true);
                    }))

            
<strong>BCC:</strong>  Html.Kendo().AutoComplete().Name("bccAddress")
                    .DataTextField("Email")
                    .Separator(";").MinLength(4).Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(r =>
                        {
                            r.Action("SearchAD", "Home").Data("AdditionalData");
                        })
                        .ServerFiltering(true);
                    }))

    function AdditionalData() {
        var text = $("[the autocomplete id]").val();  //get the ID or any other identifier
        var i = text.indexOf(";");
        var value = text.substring(i + 1);
        return {
            text: value
        }
    }

Hi team,

We recently upgraded Telerik ASP.Net MVC to 2025.3.825, All the changes are good But when we try to create build the code through GIT-Hub CI/CD process getting below error.

Can you please help us to resolve the issue.

D:\actions-runner\_work\TestProject\Source\Test\packages\Telerik.Licensing.1.6.16\build\Telerik.Licensing.targets(29,3):
 error MSB4062: The "Telerik.Licensing.Tasks.ResolveTelerikProducts" task could not be loaded from the
 assembly D:\actions-runner\_work\TestProject\Source\Test\packages\Telerik.Licensing.1.6.16\build\..\tasks\netstandard2.0\Telerik.Licensing.Tasks.dll. 
 Could not load file or assembly 'Microsoft.Build.Utilities.Core, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or 
 one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, 
 that the assembly and all its dependencies are available, and that the task contains a public class that 
 implements Microsoft.Build.Framework.ITask. [D:\actions-runner\_work\TestProject\Source\Test\Test.Web\Test.Web.csproj]

I just upgraded my application and now I am getting a license runtime error.

Here is the exact error I am receiving: 

Could not load file or assembly 'Telerik.Licensing.Runtime, Version=1.6.5.0, Culture=neutral, PublicKeyToken=98bb5b04e55c09ef' or one of its dependencies. The system cannot find the file specified.

I went through the steps to download the key and I received a message stating that my key was successfully downloaded.  

Am I missing a step? 

Thanks for your help!

We have a column of type text, and want to change the default filter from 'equals' to 'contains'.

This doesn't seem to have any effect: 

.Filterable(f => f.Cell(c => c.Operator("contains")))

This does not seem to work in the context of the MVC Grid: jQuery Set the Default Filter Operator in the Grid - Kendo UI for jQuery
