Eek.. June already.. I’ve been on my hols, come back and realised that I’ve been somewhat remiss in posting to my blog.<\/p>\n
So without further ado, I’ll talk about my current expedition into the realm of SharePoint code. Todays task is EventHandlers from code.<\/p>\n
Attaching Event Handlers from code is pretty easy, the SDK shows various methods all of which seem to do the trick. However, I want my Event Handler to have a specific GUID as it’s ID. The idea behind this is that my management application knows what the different event handler ID’s are in all the environments.<\/p>\n
And this is where my plan has currently fallen apart.<\/p>\n
I’m using the following code to add the event handler (after correctly checking that an event handler of the same name and assembly doesn’t already exist of course..)<\/p>\n
\r\nif (!itemDeletingExists)\r\n{\r\nSPEventReceiverDefinition deletingReceiver = erdc.Add(new Guid(\"F649A610-2C83-4f11-B73F-A7D1656DEACB\"));\r\ndeletingReceiver.Name = \"ResourceEventsItemDeleted\";\r\ndeletingReceiver.Type = SPEventReceiverType.ItemDeleting;\r\ndeletingReceiver.SequenceNumber = 10000;\r\ndeletingReceiver.Assembly = assm;\r\ndeletingReceiver.Class = nsp;\r\ndeletingReceiver.Update();\r\nreceiverAdded = true;\r\n}\r\n<\/pre>\nWhen you step through the code above, the event handler is added quite happily and the deletingReceiver.ID = the guid used in the constructor.<\/p>\n
So further down my code we grab the collection of event handlers currently held by the content type and sure enough, there is our (in this case 3 of them) event handlers, sitting happily in the collection.<\/p>\n
However, if you grab the EventReceiverDefinition for each of them, the .ID is all zeroes… Is this a bug or intended behaviour? Further investigations ongoing..<\/p>\n
