Validation in child objects

neste posted on Thursday, October 29, 2009

Hello -
I've just started using the CSLA framework - and I need some guidance on how to tackle the following issue:
I have a Customer business object that has two address child objects: physical and mailing. The validation rules for the physical address are different from the mailing address. I created an Address class on which I set an AddressType field to differentiate between the two. How do I add business rules to the Address class that would differ between the two address types? Shared rules would not work.
Any help is much appreciated! Thank you.

Create a validation rule method in the address class that branches on the address type, like in the example below:

private static bool RequireZipCode(T target, Csla.Validation.RuleArgs e) where T : Address
{
if (target.ReadProperty(AddressTypeProperty) == "Mailing")
{
//Rule for mailing address
}
else
{
//Rule for physical address
}
return true;
}

Cheers

PS. How do I post formatted code?
