If you want to disable the event from firing in an list item updated event receiver, please use the method EventFiringEnabled
as follows.
public class EventFiring : SPItemEventReceiver
{
public void DisableEventFiring()
{
this.EventFiringEnabled =false;
}
public void EnableEventFiring()
{
this.EventFiringEnabled =true;
}}
Create an instance of the class and call the method wherever appropriate :)
Happy Share Pointing :-)
