VAB Cross field validation

Topics: Validation Application Block
Jun 3, 2008 at 3:55 PM
Am I missing something - is it possible to do cross field validation with the Validation Application Block?

Field A
If Field A is not null then Field A is valid

Field B
If Field A is somevalue then Field B is valid

I do not want to do SelfValidation as I want the validation to occur through binding - so when Field B loses focus run it's rule.

This is a pretty standard requirement and could easily be done using IDataErrorInfo implementation.

Any help welcomed
