Just checked that , and the Instance of the GrandChild BO does have the parentBisinessObject set to the Son
(By the way . in you last post , you had two lines, not separated by a Blank Line... how do you do that..all my lines have a blank line in between)
Verify that the relationship is setup between the Child -> GrandChild ........ Yes That is set up on the GrandChild BO
Make sure that the Navigated event of the Child is on the correct record when the Requery is called for the grandchild............The child records are displaying in List 1. I am expecting ,as I arrow down through this list, that the Grandchildren will appear automatically in List 2 (The Grandchild) ..... is there something else here perhaps I need to call ??
Make sure that you actually have records for the grandchild (I have done that before ).... Yes I have double checked that
I just have about 25 records on each table as a test so I can see whats happening a bit clearly
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 ?
