unobtrusive-validation

I have followed some articles and tutorials over the internet in order to create a custom validation attribute that also supports client-side validation in an asp.net mvc 4 website. This is what i have until now: RequiredIfAttribute.cs [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)] //Added public class RequiredIfAttribute : ValidationAttribute, IClientValidatable { private readonly string condition; private string propertyName; //Added public RequiredIfAttribute(string condition) { this.condition = condition; this.propertyName = propertyName; //Added } protected override

I am currently facing a problem with validation after dynamically adding content. I have a view strongly typed to a model ( Order ). This Order can have many items.

I'm validating a form using the new unobtrusive validation features in ASP.NET MVC 3. So there is no code that I have written to setup jQuery validate to start validating my form. Its all done by loading the jQuery.validate.unobtrusive.js library. Unfortunately I need to whack in a 'are you sure?' message box when the form is valid but before submitting. With jQuery validate you would add the option handleSubmit when initialising like so: $("#my_form").validate({ rules: { field1: "required", field1: {email: true }, field2: "required" }, submitHandler: function(form) { if(confirm('Are you sure?
