Just wanted to stop by and say "thank you" yet again. Your clear explanation of custom validation attributes was extremely helpful and allowed me to move on to other things in my project today. Well done, sir!

Got a thumbs up for a very clear explanation and demo, this has helped me learn alot, but is there a way to validate a group of attributes at the same time? I.E. Build a search where you can search by memberID, firstname, lastname, hiredate. It should allow you to search any combination of these 4 EXCEPT if you enter nothing in all four. Basically a [required] but for a group of model attributes instead of individual(s) Thanks for the video and I will definitely be watching more.

[@bobbyrichmond5944]

I actually finished this, surprisingly easy with the new mvc. Only issue I ran into was with modelstate

[@skolker]

awesome tutorials! why you use Common folder? I know you can name it how ever you want, just want to learn the right design name/structure... does common mean custom code? if you know a good link where I can check names/structures developer use, pls share , hope to hear from you.. thanks!

I do everything as you say, but the client side validation is not working with the costum attributes. I referenced the three nececcery .js file, In the web.config the two option is true. The other buildt in validation messages(required) are appeared, but my custum message is'nt. On the server side the ModelState is false, and in my costum attribute i sent back false value. But nothing appeared and the post has sent. :( Can you give me some help?

[@RonanClancy]

[@ciscoinch1230]

TO start , always go back to DB table creation pay attention in first 2 min -- back to part 80 so as to create VS solution (begin here -- kzbin.info/www/bejne/qoTdc4GIdsujfbs )

[@thaeerthaeer77]

[@Squackles14]

very strange u cant put datetime.now in the constructor.

[@bobrbudside7547]

How do you do that validation is fired on the client-side ?? I'm using jquery.validate.js and jquery.unobtrusive-ajax.js but still method isValid is fired after posting form. Reqired attr is fine, it works.
