Attach EventReceiver to all sharepoint site listings

Question

Is it possible to write an eventreceiver that runs when any list is updated. The listtemplateid list that we must specify for the eventreceiver makes our code special for one list breed. What if we want the code to be executed for events in all the lists of the site?

Answer 1

I have the exact same requirement.

Perhaps you can connect the event receiver to System ContentType (all content types inherit one, with id 0x)

I will check to see if this is possible by creating a Feature with FeatureReceiver and programmatically adding it to the System Content Type. Some details here .

My way to finding a solution

Ok, I tested the console application a bit.

• I tried to add EventReceiver to the system (0x) . The ContentType.Update (true, false) method is called, which updates all child elements - and not the System ContentType , not the childs . Turns out you can't change those contentTypes using ReadOnly || Sealed set to TRUE
• Tried adding EventReceiver to Item (0x01) ContentType . As you can see from this, all ContentTypes are still inherited from this (see the ContentType hierarchy ). Custom content types may exist that inherit from the System, but not those made in the graphical interface. Updating this type of content has really updated all ContentTypes child elements (all content types except ReadOnly or Sealed )

How to connect global EventReceiver to all elements

So, the solution that will work will look like this:

• Iterate through all the lists, set ReadOnly or Sealed to false if you want these types of content to have EventReceivers with you.
• Add EventReceiver to existing content types in lists ( SPList.ContentTypes )
• Add EventReceiver to ContentType ( SPWeb.ContentTypes ) with id 0x01 so that new lists automatically add EventReceiver. New types of content also inherit EventReceivers . Also, all subweb ContentTypes inherit EventReceivers .

All three steps can be a console application or powershell script. Or a wide feature site with FeatureReceiver

Result

Sorry, my WSS is localized, but {,, ...} means that I added several types of events to the content types. As you can see, those with the ReadOnly or Sealed False attribute are not affected.
