Remote event reciever to allow renaming a files but prevent deleting them

Question

We have a requirement inside our SharePoint online site, is that we need to allow renaming files inside document libraries but prevent deleting the files. now in SharePoint Permissions; rename & delete are treated the same. So if we define a custom permission level to allow users to add, edit but not to delete >> then this permission level will also not allow renaming files.

So any advice how we can allow users to rename files but without allowing them to delete the files using remote event receivers?

Hi @john john,

The following code snippet will prevent item deletion and also notify the user of what happened

public override void ItemDeleting(SPItemEventProperties properties)
{
    base.ItemDeleting(properties);
    properties.Status = SPEventReceiverStatus.CancelWithError;
    properties.ErrorMessage = "This item cannot be deleted; Contact your administrator";

}
