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 ?

In the code that you provided, I don't see anywhere that you call the ListView2.Requery(). It is hard looking at an example like this as there is not much to go on since you did not provide a full sample. If you have a sample that illustrates this that you could share then please post that as it would be easier to work with.



The reason I am not sure exactly where to direct you as I don't exactly understand where your issue is. Setting up a parent->child->grandchild and event deeper relationship is something that we work with on a daily basis...including within ListViews. So at this point I know that it is just a matter of configuration. But I am not sure exactly at which point you are having the issue.



From just looking at your code, I see one issue here:







You never call the listview2.Requery(). Based on my assumption of your code, shouldn't the code read:
