data-annotations

I have 2 classes: Client and Survey. Each Client can have many surveys - but only one default survey. I have defined the classes like this: public class Client { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int ID { get; set; } public string ClientName { get; set; } public Nullable<int> DefaultSurveyID { get; set; } [ForeignKey("DefaultSurveyID")] public virtual Survey DefaultSurvey { get; set; } public virtual ICollection<Survey> Surveys { get; set; } } public class Survey { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int ID { get; set; } public string

I'd like to use the data validation attributes in a library assembly, so that any consumer of the data can validate it without using a ModelBinder (in a console application, for instance). How can I do it? TheCodeKing Actually this is pretty cool. I used it in a WFP validation implementation recently. Most people end up writing lots of code using reflection to iterate the attributes, but there's a built in function for this. var vc = new ValidationContext(myObject, null, null); return Validator.TryValidateObject(myObject, vc, null, true); You can also validate attributes on a single named

I am using DataAnnotations to validate my ViewModel on client side with jquery.validate.unobtrusive and on server side in ASP.NET MVC application. Not so long time ago, I figured out that I can write validation like this: [Required(ErrorMessage = "{0} is required")] public string Name { get; set; } That way I can easily define some general strings in config or in resources and always use it in DataAnnotations . So it will be easier to change validation messages in my whole application in future. Also I know that there is a FluentValidation library that allows to add validation rules to already

I am using DataAnnotations for my model validation i.e. [Required(ErrorMessage="Please enter a name")] public string Name { get; set; } In my controller I am checking the value of ModelState. This is correctly returning false for invalid model data posted from my view. However, when executing the unit test of my controller action, ModelState always returns true: [TestMethod] public void Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error() { // Arrange CartController controller = new CartController(null, null); Cart cart = new Cart(); cart.AddItem(new Product(), 1); // Act var

I'm using VS2008 SP1, WCF Ria Service July 2009 CTP. I found out that MetadataType does not work in partial class mode, really don't know what I have missed out: Work:- public partial class Person { private string _Name; [Required(AllowEmptyStrings=false, ErrorMessage="Name required entry")] [StringLength(3)] public string Name { set{_Name = value;} get{return _Name;} } } class Program { static void Main(string[] args) { Person p = new Person { Name="123432" }; List res = new List(); Validator.TryValidateObject(p,new ValidationContext(p,null,null), res,true); if (res.Count > 0) { Console

I'm working with the Code First feature of Entity Framework and I'm trying to figure out how I can specify the column data types that should be created when the database is auto-generated. I have a simple model: public class Article { public int ArticleID { get; set; } public string Title { get; set; } public string Author { get; set; } public string Summary { get; set; } public string SummaryHtml { get; set; } public string Body { get; set; } public string BodyHtml { get; set; } public string Slug { get; set; } public DateTime Published { get; set; } public DateTime Updated { get; set; }
