This approach actually works (update the target for delete onvalidatedelete, and then prevent the delete onpredelete or onpostdelete)
it will updates the "entity to be deleted", and still gives the business process errors - preventing the delete
There are two drawbacks in the approach
1) The UI will no update immidiatly. You have to press F5 or similar to get the new values of fields
2) OnValidateDelete does not trigger on cascade delete. The result is, that if the reason for delete comes from a parent with cascade delete configured, the OnValidateDelete will not trigger, and the record will be left unchanged in this situation.
Otherwise it is a prettye good solution.
Wow. You don't have to do all that.
In the plug-in registration tool, you have it trigger on the "Delete" message. So you know context.MessageName equals "Delete", you don't have to check that. You don't have to check context.Stage either. Create a "preImage". Then instead of putting a condition on InputParameters you put a condition on PreEntityImages. The meat of the plug-in literally only needs to be 3 lines (inside your try/catch). if (context.PreEntityImages.Contains("preImage") && context.PreEntityImages["preImage"] is Entity) {
throw exception
}
Agree with Wei Jie Fun
This should be the first and only option - In fact, delete should be removed from everyone (all types records) except a select few high level users and even then it is questionable.
It should be a periodic review of deactivated records and only someone with System Admin role should delete (even then supervised) - because there is no recovery for erros
Even then, doesn't seem to work for activities but i'm working on that

@Alex : client didn't liked the plugin approach to stop user from deleting the record, instead we removed the rights for the user and it worked.
great!
Thank you every one for the help, very much appreciated.
Below is the code that worked for me, on the pre validation i deactivated the record and on post operation trigger exception with the message.

Shahbaaz,
My apologies ! Me too tried with different approach , seems this is not working as we can not set order in the workflow and second due to transaction, no matter we are creating two workflow ,its executing in same transaction. So its not working using OOB workflow as well.
Using plugin you will also face same issue , you can not pop out message in the same transaction saying Business Process Error.
There is two approach you can follow.
First show error using workflow while delete the record, saying that you can not delete the record , rather deactivate the record .
Second approach will be remove delete permission from the entity.
Hope this helps.
Hi
I have done a bit of testing on the solution i suggested above, the reason for it not working is that when it executes the Stop step with Cancel status, it also cancels the child workflow it initiated.
I know you can simply remove the delete privilege but you may want to prevent even Sys Admins deleting it.
If you create plugins on Pre Validation and post operation of Delete message and make the record inactive in pre-validation (any DB operation at pre-validation stage wont be rolled back)
and then in your post operation of delete throw an invalid plugin exception
@Goutam, but it will delete the record, please can u provide the screenshot ?
Wei Jie Fun, that is the last option
