Substitute for old DocumentEvents.Copy.Before / After in XbyK?

Aren't you looking for the global event handlers?
https://docs.kentico.com/documentation/developers-and-admins/customization/handle-global-events

It should be pretty much the same as in Kx13.

Hi Chyde,

We have an alternative option if you are using a specific object type, reference to this https://docs.kentico.com/documentation/developers-and-admins/customization/handle-global-events/handle-object-events

public class CustomObjectBeforeUpdateHandler : IInfoObjectEventHandler<InfoObjectBeforeUpdateEvent<CustomObjectTypeInfo>>

Agree with you Sean, Thanks for correcting me, here we have an reference to the handler https://api-reference.kentico.com/api/CMS.ContentEngine.ContentItemEventHandler-1.html and

Nikhila,

If you want to check what public APIs are available to developers you can use https://api-reference.kentico.com/api/CMS.html and perform a simple search.

General purpose AI chat experiences provided by frontier models, like ChatGPT or Gemini, might provide incorrect information when asking about Xperience by Kentico because they confuse Xperience by Kentico's API surface with Kentico Xperience 13 (and previous versions) or because they have some connection between APIs common in the ASP.NET Core space and Xperience.

If you check in the Xperience by Kentico API reference you can see that IContentItemEventsHandler and IWebhookHandler are not part of the public API (they aren't even private or internal APIs 😅).

Additionally, you can ask the AI in our docs - https://docs.kentico.com/ - because it has up-to-date vector embeddings of the docs content and will be a lot more accurate with responses.

Thank you for the responses! Unfortunately, I'm still a little confused - here is the old K13 code I'm trying to transition:

DocumentEvents.Insert.Before += Document_Update_Before;
DocumentEvents.Update.Before += Document_Update_Before;

DocumentEvents.Copy.Before += Document_Copy_Before;
DocumentEvents.Copy.After += Document_Copy_After;

The first two lines I've (in XbyK) handled with this (I have a base handler so both are ultimately calling the same thing):

parameters.Services.AddInfoObjectEventHandler<InfoObjectBeforeUpdateEvent<ContentItemInfo>, UniqueIdentifierOnProductBeforeUpdateHandler>();
parameters.Services.AddInfoObjectEventHandler<InfoObjectBeforeInsertEvent<ContentItemInfo>, UniqueIdentifierOnProductBeforeInsertHandler>();

It's the last 2 lines above that I am unsure of - I see no Copy-related events exposed in the API. It seems in K13 there was a distinction between Insert/Update/Copy that I can't find in XbyK.

I've looked here: https://api-reference.kentico.com/api/CMS.ContentEngine.ContentItemEvents.html, and there is no Copy event listed, nor anything that seems to resemble it.

So, how do I implement what used to be a valid event in K13 that seems to no longer exist? Or - and this is 100% possible - am I missing something?

There is a specific string field in K13 that is in a custom table that before and after being copied, the field is manipulated to ensure it remains unique throughout the copy process (a suffix is added to the string before the copy, and them removed after the copy).

The field doesn't contain a GUID - it's just an underlying nvarchar(200) field that must remain unique. So, in translating to XbyK I'm just trying to make sure the business rule is still in place. When I couldn't find a copy event API, I reached out to make sure I wasn't missing anything.

Thank you all for your responses! We will figure something out!
