Ok, Got it.

In a nutshell, my applications has 3 forms and my parent relationship call was not at the highest form.

This is what I had.

Mainform

Contains a datagridview with a mainBO. From the Mainform, I have a childdialog calling the sub Entryform with the mainBO.

Entryform

This form contains the mainBO and childbo.

I had the parentchild relationship established in the Entryform.

ChildEntryform

Contains the childbo

When I moved the childbo up to the Mainform and established the relationship there, all the relationships worked.

Yeah, you are missing something really basic as this is not a complicated implementation....instead of going through a hundred forum posts out here, do one of two things, or both.

Open one of the SF samples that shows how to use a relationship (CRM sample application, ChildFormDialog sample, etc).
Post a quick sample of your basic implementation on this thread and I will correct your problem (within the basic sample...not your application code) so you can see what you are missing....this is faster than going back and forth.

Did you include the instance of the child BO that is dropped on the form in the Form's add? I.e. set the appropriate IncludeInForm(Add/Delete/Edit/Save/Undo/Navigate) properties?

Yes,

Now, is the relationship code executing based off of the parentbo editing state? I have a listview on the parent form which is the child of a parent form.

And on your parent form, for your ChildBO, you have set the ParentBusinessObject property?

Hi Michael.

Just checking, but you have set the Primary and Foreign keys on the Child-Parent Relationship Editor of your Child BO, right?

Also, have you set the ChildBO ParentBusinessObject property on your Child form?

I cannot seem to get the relationship to work properly on add. When I add a record, the record does not receive the parent key value from the parent bo?

I think that I have covered everything

I have two tables

Parent Table

Child Table

I established the relationship in the DDT

Established to parentrelationship on the BO

Established the parent BO in the BO on the form.

Configured Childform.
