    One of my favorite features of ASP.NET MVC 2 is the support for client validation. I’ve covered a bit about validation in the following two posts: ASP.NET MVC 2 Custom Validation covers writing a custom client validator. Localizing ASP.NET MVC Validation covers localizing error messages. However, one topic I haven’t covered is how validation works with globalization. A common example of this is when validating a number, the client validation should understand that users in the US enter...

    It’s tiny tip time… Since all the fuss about [Required] validators in ASP.NET MVC 2, the validation behaviour was changed in Release Candidate 2. Previously, the framework only validated fields that were actually posted in the form, whereas now it validates all the fields on any model object that the model binder gives you.

Suppose you have the following simple model with two properties. public class Product { public int Id { get; set; } public string Name { get; set; } } And you are creating a view to create a new Product. In such a view, you obviously don’...

    One of the exciting feature of ASP.NET MVC is(?) auto generating the view of the model with DisplayForModel/EditorForModel statement, it gives a nice extension point for the application developers to customize the view. But in the latest release (MVC2 RC2), it looks like the feature is no longer available.
