Limitation of ModelState.IsValid in ASP.NET MVC 3

StackOverflow https://stackoverflow.com/questions/10494168

Question

I always use ModelState.IsValid for check all of my model validation validated correctly in Server Side, but I think there is a limitation to use this. For example I define a Remote Validation attribute, but if I disable javascript then ModelState.IsValid don't check Remote Validation and always return true, Where is the problem? this is a limitation for ModelState.IsValid or is my fault? If necessary I can Add all my implementation.

Was it helpful?

Solution

This question has come around a few times. The answer is: it doesn't validate on the server-side, you have to perform the validation action yourself. See also following SO posts:

Of course, it would be nice to be able to validate it anyway on the server-side. Luckily some nice guy made an implementation for it. You can find his short blog post: http://www.tugberkugurlu.com/archive/asp-net-mvc-server-side-remote-validation .
