attach programmatically an event receiver to an list

Question

Hey,

i have to attach programmatically an event receiver to an list. For this I found a good tutorial under:

http://bramnuyts.be/2011/04/01/add-an-event-receiver-to-a-specific-list-programmatically/

In this tutorial is this code:

const string _listName = "test";
const SPEventReceiverType _eventType = SPEventReceiverType.ItemAdded;

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    SPWeb oWeb = (SPWeb)properties.Feature.Parent;       
    oWeb.Lists[_listName].EventReceivers.Add(_eventType, Assembly.GetExecutingAssembly().FullName, 
"EventReceiverProject1.EventReceiver1.EventReceiver1");
}

So it works with fine for one event receiver type. But how I has to change the code when I like to ad more than one event receiver type (like ItemAdded and ItemUpdated)?

Thanks for your help

Stefan

Answer 1

It is a collection, you can just update your code to add more (using the same code snippets above).  Is that what you are asking?

Here. I am assuming Your EventReceiver1 class have both ItemAdded and ItemUpdated defined.

 oWeb.Lists[_listName].EventReceivers.Add(SPEventReceiverType.ItemAdded, Assembly.GetExecutingAssembly().FullName,
        "EventReceiverProject1.EventReceiver1.EventReceiver1");

            oWeb.Lists[_listName].EventReceivers.Add(SPEventReceiverType.ItemUpdated, Assembly.GetExecutingAssembly().FullName,
        "EventReceiverProject1.EventReceiver1.EventReceiver1");


            oWeb.Lists[_listname].Update();

Credit to Chris. I have simply provided code for what he already mentioned. :)

Thanks for your help.

The code example helps me a lot.

In the eventreceiver1 class added und updated method is the same visual studio creates automatically when I add an event receiver to my solution.

When I activate the feature SharePoint hangs the method Itemupdated from the class as an event receiver on the list. Is this thing right? , then I thing I have understand it.

Sorry when I answers come a bit late. But I seat in the train and the internet connection is most of the time broken.
