For the autogenerated template, our Project Templates include the pre-built editors out-of-the-box. If they were removed, these can be found at the default installation which is noted below.
C:\Program Files (x86)\Progress\Telerik UI for ASP.NET Core [VERSION]\wrappers\aspnetcore\EditorTemplates\razor
Alternatively, if the goal is to use a custom editor, it is correct that this will require adding a custom editor. For a full example of this, see the Creating Custom Editors for Bound Properties documentation.
Ultimately, the ASP.NET Core HTML and Tag Helpers are wrappers around the jQuery Widgets and the same functionality is available. However, it shouldn't be required to create a custom editor as described.
Although, I may be missing something. Can you let me know if you experiencing a different issue in this scenario?
In the meantime, please let me know if you need any additional information. Thank you and I look forward to your reply.
