Currently I'm using following pattern to get verification errors out of CurrentItem<T>
 
public List<string> ValidationErrors
        {
            get
            {
                var validationErrors = new List<string>();
                if (this.CurrentItem != null)
                {
                    validationErrors.AddRange((from errors in this.CurrentItem.EntityAspect.ValidationErrors select errors.Message).ToList());
                }
                return validationErrors;
            }
        }
 
I want to make sure child items also covered, in case I do header/detail manipulation I want to see errors from "Order" and "OrderLine"
 
EDITED:
 
I know how to easily get all entities within manager but it might contain other records I don't care about. I really want to verify just "Graph" So, ideally I want to iterate only main item and it's childs/subchilds.

Hi katit,

You might want to get the entity graph. i.e.: 


  var rootEntities = new List<Entity>();

  rootEntities.Add(someEmployees);



  var spans = new List<EntitySpan>();



  EntitySpan span = new EntitySpan(typeof(Employee),

    EntityRelations.FK_Order_Employee,

    EntityRelations.FK_OrderDetail_Order,

    EntityRelations.FK_OrderDetail_Product);



  spans.Add(span);



  var entityGraph = manager.FindEntityGraph(rootEntities, spans, EntityState.AllButDetached);
