I'm supporting a classic app that still uses the Telerik.DataAccess.Fluent package 2020.0.428.1 (used in SiteFinity CMS) and there is an issue with the version of Mono.Cecil in the package (0.9.6.0) that fails to "enhance" when compiling under Visual Studio on Windows arm64

Unhandled Exception: System.NotSupportedException: Specified method is not supported.
   at Mono.Cecil.PE.ImageReader.ReadArchitecture()
   at Mono.Cecil.PE.ImageReader.ReadImage()
   at Mono.Cecil.PE.ImageReader.ReadImage(Disposable`1 stream, String file_name)
   at Mono.Cecil.ModuleDefinition.ReadModule(String fileName, ReaderParameters parameters)
   at ceciltest.Program.Main(String[] args)

The defect has been fixed in Cecil (https://github.com/jbevain/cecil/issues/337) so it would be good to get this resolved for future use, if not for those SiteFinity users, but for the 4000+ users who are still downloading the library

Your licensing mechanism (which is a nuisance at the best of times) seems to be now actively interfering with agentic AI coding.  The newer agents now generate and run scratchpad code and iterate off what they see in the UI.  But they get stuck because your "you need a license key" message overlays everything.  How do I get around this roadblock?

Hi Telerik Team,

I am using RadFileExplorer with a custom FileBrowserContentProvider. I noticed that ResolveDirectory() and GetFiles() are only called the first time a folder is opened. After that, navigating back to the same folder (either from the tree view or by opening folders in the file list) does not invoke these methods again, so the folder contents are not refreshed and changes are not displayed. If I click the Refresh button in RadFileExplorer, the folder contents are refreshed correctly and the latest files are shown. I tested this with both 2025.1.416.462 and the latest Telerik version, and the behavior is the same. Is this expected caching behavior? Is there a supported way to force RadFileExplorer to reload the current folder and call ResolveDirectory() and GetFiles() again?

Thank you.

Hi,
my annual perpetual DevCraft license expires in July.

After researching online, I learned that this product is no longer available for purchase online. Only those who already had it can continue to use it and maintain it.

Can you confirm that this is true?

I'm considering switching to a subscription: for projects I've already created (using Telerik Blazor, MAUI, ASP.NET MVC, ASP.NET CORE), could I run into any issues compiling and/or publishing Docker?

Can you explain the difference between the two licenses in detail (excluding products that are only available under a subscription)?

Thanks in advance

Marco

How can I resolve issues with integrating an age calculator into a Telerik-based application? Specifically, I'm facing problems with accurate age calculations and data synchronization between the calculator and Telerik components. Any advice or solutions would be appreciated.

We do have a Kendo Scheduler bound to a remote data source. 

The transport configuration of this scheduler's data source is done using remote urls (for CRUD), and this works perfectly,

On the server side, we make a lot of checks. So if some requirements are missing, Create, Update or event Destroy operations wouldn't pass and user will be shown the meaningful error.

The problem we're facing now is like the following :

For the Destroy action, what kind of response should we send back (from the server) to the scheduler component (in the browser on the client side ) to prevent removal of events in the UI.?

We've tried :

  • Sending back HTTP 500 status code
  • Putting an error field in the response and linking it to the schema.error configuration

But events are still removed from the UI, nevertheless the error event is fired. We even use this event to notify errors to end used.

Thank you.

Hi everyone!

I'm trying to place a NumericTextBox inside a FormItem because I need to apply some validations that are defined in another file, and also call a method that returns a calculated result. However, whenever I try to do this, my project fails to run.

Any advice or insights would be appreciated!
