data-annotations

I'm building a MVC web application with C#. Since the site will be multilingual, I've implemented my own ResourceManager. This class is responsible for fetching the required resource strings from a database/cache depending on the currents thread culture and works fine so far. My problem is, I'd like to use the my custom ResourceManager solution to fetch validation error messages when for example using the Required Attribute on a property. Can this be done? The RequiredAttribute allows to use a custom resource manager : [Required( ErrorMessageResourceType = typeof(CustomResourceManager),

I created an EF4.1 code-first model (may or may not be important), and I'm trying to get default values for my Create scaffold template. My model looks like: class Person { [DefaultValue (18)] public int Age { get; set; } } And then my Create view looks like: <div class="editor-label"> @Html.LabelFor(model => model.Age) </div> <div class="editor-field"> @Html.EditorFor(model => model.Age) @Html.ValidationMessageFor(model => model.Age) </div> I would expect at runtime, that the EditorFor would pre-populate the textbox with "18", but it does no such thing. Am I misunderstanding what the

This is more of a theoretical question. I'm currently examining the MVC 3 validation by using ComponentModel.DataAnnotations, and everything works automagically, especially on client side. Somehow something checks for those attributes, and generates javascript for the validation (or html5 attributes, if using unobtrusive mode), and it works. My question is that what generates the client side javascript and how can I access and modify it? For example I want to handle the given dataannotation attributes a little differently, or handle custom attributes (I have found that I can derive them from

I'm running EF 4.2 CF and want to create indexes on certain columns in my POCO objects. As an example lets say we have this employee class: public class Employee { public int EmployeeID { get; set; } public string EmployeeCode { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public DateTime HireDate { get; set; } } We often do searches for employees by their EmployeeCode and since there are a lot of employees it would be nice to have that indexed for performance reasons. Can we do this with fluent api somehow? or perhaps data annotations? I know it is

I'm using the MetaDataType Attribute on my domain model class. It it supposed to move the attribute information from the referenced class into the class that the MetadataType attribute has been set. But it doesn't do as advertised. What is causing the issue here? [MetadataType(typeof(ComponentModelMetaData))] public partial class Component { public int Id { get; set; } public string Name { get; set; } public ICollection<Repo> Repos { get; set; } public string Description { get; set; } } public class ComponentModelMetaData { [Required(ErrorMessage = "Name is required.")] [StringLength(30,
