Without seeing the rest of the code I can’t say, but in the example I have shown the calculator values are properties in the ViewModel itself.

Your Example:

My Example:

How do you call AddErrorForProperty?
AddErrorForProperty(“Datacontract.FirstValue”
or AddErrorForProperty(“FirstValue”

Because both of them doesn’t work.

What about clearing all errors when a Surname changes and then validate it?

Cheers,

In the Dictionary object _currentErrors how do you remove a specific error that was added before. For instance a Surname is invalidated as being empty and then the user types numbers. My example shows the non-numeric error message but keeps the empty message when the field is obviously no longer empty.

Have you tried adding the dll using

Add Reference > Browse

instead of adding the project via

Add Reference > Projects

as suggested on stackoverflow?

I had many common chunks of functionality in a Silverlight Class Library (Common) after following a solution by Microsoft’s John Papa in the recent Silverlight Firestarte event. The EntityBase class seemed to belong in there but I couldn’t reference it in my Unit Testing project because “it targeted a different framework family”.
