Validating Child object based on Parent

cash_pat posted on Monday, September 14, 2009

Hi all,

How do i validate a child object based on its parent object's property.

   If Me.Parent.VoucherType = VoucherTypesEnum.Purchase Then

           ValidationRules.AddRule(AddressOf CommonRules.StringRequired, New RuleArgs(CompanyVoucherNoProperty), 0)

     End If

But the parent property has a value of nothing when the object is created.

Any ideas.

thanks

Hi,

I would suggest that you write your own custom rule and within the body of the rule you check the parent.VoucherType and determine whether field is required or not.
