I have a Parent,Son,Grandson which I am trying to display. The Parent is on a Miantemence Form and works fine. I have the Son and Grandson in two ListvIews , side by side. The Son is dispaying fine. When I land on each record of the Son, I want the Grandson records to show, just for the relevant son. Nothing is being displayed on the Grandson list. I have set up as follows: The Foreign  Key for the Grandson is got from the Primary Key on the Son

SonBo.Navigated... This.ListView2.Requery();    //to requery the Grandson ListView

Grandson.ListView.Populating...  e.Parameters[0].value  = this.SonBO["Son_PK"];  //to get Primary key from the Son

Grandson ListView.Properties... PopulateOnFormLoad=Manual  MethodToExecute=FillByParentPrimaryKey(Int32)  (primary key is Numeric)

What am I missing ?

Hi Gerard,



Sorry I don't have time now to explain in detail, but I changed the logic of your sample (see attached projects). Look at the listviews population method and at the BOs Navigated events.



Your BO relation definitions are OK. You will see data from record 2.



Have a nice weekend!
