Hi,

Hi,

While waiting for response of one to one relationship thread, I tried to use IncludeInFormAdd, IncludeInFormDelete and etc property to achieve my goal (but I still hope someone can help on my previous posted issue). At first it works fine. But don't know why it just not working now.



I have the BO setting as below. After some debugging, I found that, BaseForm call child BO CompanyAddress.Add() before parent BO CompaniesBO.Add(). Even I set InitializationPriority.



Anyway ideas?



My topmost level BO - CompaniesBO is using PrimaryKeyIsAutoIncremented = true. My child BOs - CompanyAddress and CompanyContacts PK is composite key. Therefore, I set both PrimaryKeyIsAutoIncremented = false.



CompanyAddressBO - CompanyID, AddressTypeID

CompanyContactsBO - CompanyID, ContactTypeID



When I click on new button, I would get error



BusinessLayerException

   An error occurred while retrieving the primary key from the parent business object.

BusinessLayerException

   The CurrentRow could not be evaluated because the CurrentRowIndex is out of range. Business object record count: 0. CurrentRowIndex: -1.

Hi,

Are you using WinXP SP2?

I tried to create an user control in the same project with my linklabel subclass. VS prompted error, and mentioned it is WinXP SP2 problem.

I am running WinXP SP2 and not having any trouble.  Chan, create me another solution that has nothing in it but a subclassed LinkLabel and a form with it dropped on.  This should prove two things, one, it may have something to do with you other solution, and two, if you can reproduce it in a second solution then it is hard and I should be able to reproduce it on this side using your sample.

Hi,

Here is the project, which have problem mentioned.



If you still unable to reproduce it, I can arrange to let you to remotely access my laptop.



Thank you

OK...this definitely failed and I was able to reproduce it.  I see several things wrong with the solution, but I do not think this is the problem.  I will look into it some more and get back with you.

OK...here is the problem.  It is the designer attribute of the StrataFrame LinkLabel.  There is a designer that allows the localization of the control to be set through a form designer.  This designer is in the Extensibility assembly which you are not allowed to distribute.

To get around this problem, just overwrite the designer attribute on your inherited control.  This way you get all of the benefits of the inheritance, you just will not have access to the form designer, which is really no big deal.

Second, your application is not using a StrataFrame application.  This is going to cause all kinds of problems.  When you create a StrataFrame application, use the StrataFrame Application template.

Attached is a sample that has a working inherited LinkLabel and a StrataFrame application.

Finally, note that the System.Design reference must be added in order to access the ControlDesigner attribute.
