Hi

I'm new to LLBLGEN and I was wondering if there is a way to check if an entity or one of its related entries has changed since last save.

Or even better an event that would fire if an entity or one of its its related entries has changed.

I realize that I can do a recursivly search for all entities and then subscripe to the EntityContentsChanged event.

But is there an easier way?

Thanks,

Try using the IsDirty flag.

But isn't the IsDirty flag only reflecting the changes in entity itself? I am looking for something that will tell if the entity or one of its related entities has changed.

Yes it is. I ment doing a recursive search for a IsDirty == true, same way you would have done to subscribe for the EntityContentsChanged event.

Anyway I don't think there are any other way than these.

I found the ProduceTopologyOrderedList method in SD.LLBLGen.Pro.ORMSupportClasses that makes the job pretty simple

    public bool HasChanges()
    {
      ObjectGraphUtils ogu = new ObjectGraphUtils();
      List<IEntity2> list = ogu.ProduceTopologyOrderedList(myRootEntity);

      foreach(IEntity2 entity in list)
      {
        if(entity.IsDirty || entity.IsNew) return true;
      }

      return false;
    }

Thanks for the replies
