Disable Sharepoint 2010 Event Handler

Question

I have two different event handler solutions in a list. One event handler runs on multiple lists if an Item is being Updated. Lets call that event handler (A). I have another event handler that runs on only one list. Lets call that event handler (B). Both
the event handlers (A) and (B) runs on the list that I am talking about. When an item is being updated, I have some scenarios when I want to disable event handler (B) but not (A). Event Handler (A) should run as usual. How do I disable just one event Handler?
I am using the code below to disable and enable the event handlers. This is disabling both the event handlers.
EventFiring eventFiring = new EventFiring();
eventFiring.DisableHandleEventFiring();
....some code
eventFiring.EnableHandleEventFiring();

Hi,
According to your description, you may want to manage the execution of the two Event Receivers for a specific list.
As a common practice, it is not recommended to control an Event Receiver from another Event Receiver, I would suggest you use the Event Receiver (A) only to capture the ItemUpdated event.
Since you might have different logic in the two Event Receivers, a possible workaround I can provide is that you can execute the two different logic accordingly by checking the name of the list which the item event occurs in, usually, an if…else… block would
do the trick.
