Multiple document library event handlers on a library

Ever wanted to do this? ... Me too!

Unfortunately there is not a nice way to do this... however if you are able to modify the code there is a way to string a few of them together.

Take the first document library event handler, inherit from the second. Add your code to do what ever you need to. Call your base class.

E.g:

public class MyHandler : SecondHandler, IListEventSink
{

   .
.
.

   public void OnEvent(SPListEvent event)
{

               base.OnEvent(event);

        }
}

I mean this hack ... but it will allow you to have a few handlers with separate code etc...

  Why not write a generic handeler that has an internal collection of handlers.
  
  then...
  public void OnEvent(SPListEvent event) {
  foreach (Handler handler in collection) {
  handler.OnEvent(event);
  }
  }
  
  this way you dont have any dependancy between handlers, and you can dynamically add and re-order them.
