but... I need to access a value on the business object and at design time it's not there so I can't compile. I'm from the loosely typed dynamic world of VFP where this type of thing isn't an issue so I'm still confused with where/how to reference things at design time.



So, for instance, I want to do the following in my child CheckRulesOnCurrentRow:

If Me.ParentBusinessObject.InstrumentName = "Atlas" Then   ' <- Compile time error due to ParentBusinessObject doesn't exist at design time

         If Not CheckOnePortActive(Me.CurrentRowIndex) then

            Me.AddBrokenRule(PortSetupBoFieldNames.Activate,"Only one port can be active for this instrument.")

         End If

End If

Either of the samples given to you from Peter or Ben Hayat would work.  Since a child BO has to have the parent instance set, you can just access that property directly. 

How about:

ParentFormName.MyBO



Should give you access to it!

Hi,

I think that would be simply:

me.ParentBusinessObject....

Cheers, Peter

I have a related question... How do I access a parent business object from the child? In the instance of the child? I want to conditionally run some custom currentrowvalidation in the child business object based on a value in the parent.



Thanks.

We'll call it the same as the private field without the _, so probably ChildBusinessObjects.

Hi,

May I know the property name?

Thank you

No, but I will add a property to expose that collection for the next release.  In the meantime, you can add the property and rebuild the source code if you need it.

Hi,

How could I access childbusinessobject from parentbusinessobject? I checked SF source code and found that is a private variable _ChildBusinessObjects. However it is not exposed. Any other way to access it?

Thank you
