Access parent attributes while on an 'Add' form

[PhilP]

I have a mental block.

Imagine a tab under Accounts which has an 'Add' button. After clicking the 'Add' button, the Add form is displayed for this one-to-many entity off Accounts..

How can I access the parent account at this point, in a code snippet (eg, retrieve the parent Account ID), before the record has been saved?

Thanks

Try (IAccount)GetParentEntity()... This works as long as you are invoking the add dialog using the regular "Insert Child" options.

Typically, you will be creating the child from a parent screen anyway.  In some cases, I like to put the following code into the OnCreate event to make sure the parent is populated (this assumes we're creating a child of opportunity):

                Sage.Platform.Application.IEntityHistoryService svc = Sage.Platform.Application.ApplicationContext.Current.Services.Get<Sage.Platform.Application.IEntityHistoryService>();
                if (svc != null)
                {
                    foreach (Sage.Platform.Application.EntityHistory history in svc)
                    {
                        string str;
                        if ((!string.IsNullOrEmpty(history.EntityId.ToString()) && (history.EntityId.ToString() != Sage.Platform.Orm.Entities.EntityViewMode.Insert.ToString())) && ((str = history.EntityType.Name.ToUpper()) != null))
                        {
                            if (str == "IOPPORTUNITY")
                            {
                                IOpportunity opp = Sage.Platform.EntityFactory.GetRepository<IOpportunity>().FindFirstByProperty("Id", history.EntityId);
                                MyEntity.Opportunity = opp;
                                break;
                            }
                        }
                    }
                }

Mike, this is just what I needed, thank you very much for posting the code.
