I found a way to copy the attachments of a list item from one to another, therefore I used this code: Sharepoint Online: Copy attachment of list item to a new item using Client object model
Now I have a new problem: I have an ItemUpdating
& ItemUpdated
event receiver, which listen both to my list, where the attachments are copied to. I want to prevent them from firing before all the attachments are copied. Actually the events are called when I save the list file (as I have to save before I'm able to copy the attachments!), but this should be avoided. Is there a possibility to "pause" the event receivers for this item until the attachments are copied? I need to realize it with the client object model.
