Remote Event receiver ItemAdded and ItemUpdated issue

Question

I have added itemUpdated functionality to my receiver but i notice that it overide my itemAdded function. whenever i add a new item, my RER is not triggered. But on editing RER is triggered.

EventReceiverDefinitionCreationInformation receiver = new EventReceiverDefinitionCreationInformation();
                receiver.EventType = EventReceiverType.ItemAdded;
                receiver.EventType=EventReceiverType.ItemUpdated;


                //Get WCF URL where this message was handled
                OperationContext op = OperationContext.Current;
                Message msg = op.RequestContext.RequestMessage;
                receiver.ReceiverUrl = msg.Headers.To.ToString();

                receiver.ReceiverName = RECEIVER_NAME;
                receiver.Synchronization = EventReceiverSynchronization.Synchronous;

                //Add the new event receiver to a list in the host web
                jobsList.EventReceivers.Add(receiver);
                clientContext.ExecuteQuery();

Answer 1

Attch both ItemAdded & ItemUpdated seperately.

var lstJob = clientContext.Web.Lists.GetByTitle("LISTNAME");
clientContext.Load(clientContext.Web);
clientContext.ExecuteQuery();

OperationContext op = OperationContext.Current;
Message msg = op.RequestContext.RequestMessage;

EventReceiverDefinitionCreationInformation addEventReceiver = new EventReceiverDefinitionCreationInformation()
{
    EventType = EventReceiverType.ItemAdded, /* ITEM ADDED*/
    ReceiverName = "RECEIVER_NAME",
    ReceiverUrl = msg.Headers.To.ToString()
};

lstJob.EventReceivers.Add(addEventReceiver);
clientContext.ExecuteQuery();

EventReceiverDefinitionCreationInformation updateEventReceiver = new EventReceiverDefinitionCreationInformation()
{
    EventType = EventReceiverType.ItemUpdated, /* ITEM UPDATE*/
    ReceiverName = "RECEIVER_NAME",
    ReceiverUrl = msg.Headers.To.ToString()
};

lstJob.EventReceivers.Add(updateEventReceiver);
clientContext.ExecuteQuery();

Answer 2

It's a normal behavior, where

You have set EventType to ItemAdded

receiver.EventType = EventReceiverType.ItemAdded;

Then in the next line, the EventType is set (overwrite) to ItemUpdated again!

receiver.EventType=EventReceiverType.ItemUpdated;

So the On ItemUpdated event only will work!

---

To overcome this issue, you should add each EventType to list independently as the following

public static void ApplyEventReceiver(ClientContext context, List list)
{
// First Event ItemAdded
EventReceiverDefinitionCreationInformation eventReceiver = Helpers.BuildGenericEventRecieverWithoutEventType();
eventReceiver.EventType = EventReceiverType.ItemAdded;
if (!DoesEventReceiverDefintionExistBasedOnCreationInfo(eventReceiver, list))
{
list.EventReceivers.Add(eventReceiver);
}

// Second Event ItemUpdated
eventReceiver = BuildGenericEventRecieverWithoutEventType();
eventReceiver.EventType = EventReceiverType.ItemUpdated;
if (!DoesEventReceiverDefintionExistBasedOnCreationInfo(eventReceiver, list))
{
list.EventReceivers.Add(eventReceiver);
}

context.ExecuteQuery();
}

I have no idea why but only this work for me compare to the other answers.

 EventReceiverDefinitionCreationInformation receiver = new EventReceiverDefinitionCreationInformation();
            receiver.EventType = EventReceiverType.ItemAdded;



            //Get WCF URL where this message was handled
            OperationContext op = OperationContext.Current;
            Message msg = op.RequestContext.RequestMessage;
            receiver.ReceiverUrl = msg.Headers.To.ToString();

            receiver.ReceiverName = RECEIVER_NAME;
            receiver.Synchronization = EventReceiverSynchronization.Synchronous;

            //Add the new event receiver to a list in the host web
            jobsList.EventReceivers.Add(receiver);
            clientContext.ExecuteQuery();

            System.Diagnostics.Trace.WriteLine("Added ItemAdded receiver at " + receiver.ReceiverUrl);


            //add a second event receiver for item updated
            EventReceiverDefinitionCreationInformation receiverupdate = new EventReceiverDefinitionCreationInformation();
            receiverupdate.EventType = EventReceiverType.ItemUpdated;


            //Get WCF URL where this message was handled
            OperationContext opupdate = OperationContext.Current;
            Message msgupdate = opupdate.RequestContext.RequestMessage;
            receiverupdate.ReceiverUrl = msg.Headers.To.ToString();

            receiverupdate.ReceiverName = "Item Updated";
            receiverupdate.Synchronization = EventReceiverSynchronization.Synchronous;

            //Add the new event receiver to a list in the host web
            jobsList.EventReceivers.Add(receiverupdate);
            clientContext.ExecuteQuery();

            System.Diagnostics.Trace.WriteLine("Added ItemAdded receiver at " + receiver.ReceiverUrl);
