Client Validation

Hi,

Just i started going through silverlight 3. I have couple questions to under stand the bsic programming/approches. Validation :

Q 1: I understand, write validation in server(one place). Validation happens in client and server. I have couple of data entry forms. I will update the server when user click on save button. In this case, Can we use validators in silverlight like we use validators in .Net?

Q 2: Let assume we are getting data from WCF/Webservice (hosted by third party). How do we use validation in silverlight? Because we can't force third party team to provide validation on entity / entity properties.

Thanks

Yes, you can use validator to apply validation manually,please check this article

One way is to modify auto-generating entities, however, it will get troubles on updating webservices. Another approach is to share entities libraries between silverlight and server. please check this thread,
