To handle list and list item events, you create remote event receivers (RERs), which are web services that run externally to the Share Point farm or Share Point Online.The URL of the RER service is registered for the events it handles.And Item Added: So, when use class SPField Lookup Value, in Item Adding event Lookup Value equal to null (in . Category is not required field, what if we leave it blank?
The add-in doesn't even have to have an add-in web.
To change the events that the remote event receiver handles, open Solution Explorer, open the Properties window for the remote event receiver, expand the Share Point Events node, and then set only the events that you want to handle to True.
Add-in events are also handled by remote web services, but they are configured differently in the add-in package from list and list item RERs, so they are treated as a separate category of component.
For more information, see Workflows in Share Point.
Workflows cannot be triggered by add-in events, so add-in events cannot be handled with a Share Point-hosted add-in.
Second, a user must remove the add-in from the second stage recycle bin.
