Please note the second I try to modify Property B the error provider disappears. ![]() When blanking property A, the error provider goes away from txtBoxA and stays around txtBoxB even though I triggered the validation of property B after property A is set. When Property A has a value and property gets updated, the error provider appears around the two boxes, which is perfectly fine. The problem is that error provider is not updating. To solve this issue I called the Validator.ValidateProperty in the property setter to validate property A when B is set and vise versa. Upon Blanking property B, property A should become valid and vise versa. ![]() In other words: If Property A is set to something and property B already has a value, then property A and B becomes invalid. The requirements is to have at least one property null. I have a CSLA object with two managed properties and a custom Attribute.
