I recently spent two days on figuring out how to manage server- and client-side validation in a generic way and found a way to use xVal, DataAnnotationsModelbinder and jquery.validate so that I can implement any validation rule (even remote client-side validation) with C# code only.

Solution B works for client-side using the metadata type attribute but not for server-side, I must have got sidetracked and thought I did it when I didn't. And it looks like it's not an easy task to do as the castle validator itself will have to be edited (not really an option) or overloaded. Don't use my solution now unless I get a chance to get it working as it should be. I suggest you check out xVal, from what I understand it is meant to have support for metadataType Steve claims but I am yet to test. His approach is probably better as it's a more sophisticated framework http://blog.codeville.net/2009/02/27/xval-08-beta-now-released/. @rekna, sorry dude just downloaded the code sample and tested it, you’re right.

The ValidatorRunner doesn’t seem to handle the MetadataType…

As this gives you flexibility also to exclude validation from some pages if necessary. Thanks for the heads up regarding Castle, I will attempt to update the example when I get time, I will be testing out the new xVal library shortly, so I suggest you take a look at that and compare both implementations =) Take care.

I don't think this is intended? Can you perhaps check that back? I'm still searching for a convenient way to do the validation for our new project and your approach looks very reasonable so far, so I would greatly appreciate your review ;) Btw, Castle seems to have updates their dll. With the downloaded version your solution will not compile. Only in case you want to update ;) Hey Graham,
