Executive Summary:

How do I dynamically/programmatically change the .ParentRelationship property on an ASPX codebehind page as it loads?

Details:

I thought I would be able to populate the ParentRelationship property dynamically using the string that appears after using the builder … unfortunately though, as my accounting teacher stated, “Ignorance is bliss … but only for a time”.

MailAddr.ParentRelationship = "Person, (iID) <--> (iPersonFK)"

MailAddr = "Company Location, (iID) <--> (iCompanyLocationFK)"

MailAddr.ParentRelationship = "Courthouse, (iID) <--> (iCourthouseFK)"

MailAddr.ParentRelationship = "Employee, (iID) <--> (iEmployeeFK)"

MailAddr.ParentRelationship = "Investigator, (iID) <--> (iInvestigatorFK)"

Further testing simply served to illustrate the level of my ignorance … not to mention short lived blissfulness.  I soon

discovered that this property is really a reference to an object of the following nature:

MicroFour.StrataFrame.Business.BusinessParentRelationship

A short hunt through the code brought me to this Public Interface:

Namespace Business

Public Interface IBusinessParentRelationship

#Region " Properties "

        Property ParentBusinessObjectType() As String

        Property ParentPrimaryKeyField() As String()

        Property ForeignKeyField() As String()

#End Region

#Region " Methods "

        Function Clone() As IBusinessParentRelationship

#End Region

End Interface

End Namespace

At this point, my ignorance kicked in again and I was hopeful that I could simply assign a string to these properties and

then assign that object to the .ParentRelationship property of the MailingAddress business object.  Silly boy … as

“value of type string cannot be converted to a one dimensional array of string”.  Sigh

oMailingAddress.ParentBusinessObject = oPerson

Dim oPersonMARel As New MicroFour.StrataFrame.Business.BusinessParentRelationship

oPersonMARel.ForeignKeyField = "iPersonFK"

oPersonMARel.ParentPrimaryKeyField = "iID"

oPersonMARel.ParentBusinessObjectType = "IMA.BOLibrary.Person"

oMailingAddress.ParentRelationship = oPersonMARel

Ok, I says to myself … much less confident in my ability to do anything at this point other than poo in my shorts … let’s try this:

oMailingAddress.ParentBusinessObject = oPerson

Dim oPersonMARel As New MicroFour.StrataFrame.Business.BusinessParentRelationship

oPersonMARel.ForeignKeyField(0) = "iPersonFK"

oPersonMARel.ParentPrimaryKeyField(0) = "iID"

oPersonMARel.ParentBusinessObjectType = "IMA.BOLibrary.Person"

oMailingAddress.ParentRelationship = oPersonMARel

But, alas, no, as it is obvious I don’t know how to deal with one dimensional arrays of type string.

So, I fall back to your expertise.  How do I dynamically change the .ParentRelationship property on an ASPX page?

Should read:

You only need to change the strings to read like this:

New String() {"Value"}  '-- Creates a new string array with only one element

So, this:

oMailingAddress.ParentBusinessObject = oPerson

Dim oPersonMARel As New MicroFour.StrataFrame.Business.BusinessParentRelationship

oPersonMARel.ForeignKeyField(0) = "iPersonFK"

oPersonMARel.ParentPrimaryKeyField(0) = "iID"

oPersonMARel.ParentBusinessObjectType = "IMA.BOLibrary.Person"

oMailingAddress.ParentRelationship = oPersonMARel

Should be this:
