data-annotations

I know this is probably not possible but let's say I have a model with two properties. I write a ValidationAttribute for one of the properties. Can that VA look at the other property and make a decision? So; public class QuickQuote { public String state { get; set; } [MyRequiredValidator(ErrorMessage = "Error msg")] public String familyType { get; set; } So in the above example, can the validator test to see what's in the "state" property and take that into consideration when validating "familyType"? I know I can probably save the object to the session but would like to avoid any saving of

[Table("LegalEntity")] [ModelMetadataType(typeof(LegalEntityMeta))] public class LegalEntity : Entity<long> { } public class LegalEntityMeta { [JsonProperty(PropertyName = "LegalEntityId")] public long Id { get; set; } [JsonProperty(PropertyName = "LegalEntityName")] public string Name { get; set; } } In the Startup.cs .... services .AddCors(options => { options.AddPolicy("CorsPolicy", builder => builder.AllowAnyOrigin() .AllowAnyMethod() .AllowAnyHeader() .AllowCredentials()); }) .AddAutoMapper(typeof(Startup)) .AddMvcCore() .AddJsonFormatters() .AddApiExplorer(); My expectation is to see

I've trying to validate a property on a model I have. This property is NOT required, and so if its invalid MVC seems to be ignoring it. I've even created a custom ValidationAttribute, but nothing works. public class NumberWang : ValidationAttribute { public override bool IsValid(object value) { if (value == null) return true; int g; if (int.TryParse(value.ToString(), out g)) { if (g >= 0) return true; } return false; } } public class MyModel { [Range(0, 999999, ErrorMessage = "category_id must be a valid number")] [NumberWang(ErrorMessage = "That's NumberWang!")] public int? category_id { get;

I need to upload a csv file and I want to restrict it's extension to .csv So I added the follow property to my ViewModel: [FileExtensions(ErrorMessage = "Must choose .csv file.",Extensions = "csv,txt")] public HttpPostedFileBase File { get; set; } In my view I have the following: @Html.TextBoxFor(m => m.File, new { type = "file"}) @Html.ValidationMessageFor(m => m.File) However as soon as it hits my "ModelState.IsValid" check it returns invalid with my error message of "Must choose .csv file." I assume I'm just missing a parameter, but I haven't found a sample of this in use any where yet.

ASP.NET MVC3 code first project. In my class definition how do I set the Identity seed value. public class Account { [Key] public int Id { get; set; } What would be the syntax to set the Identity seed to 1000000? Thank you Joe Thanks Craig, after looking at https://stackoverflow.com/a/5974656/968301 it was pretty simple. Create an intializer public class MyInitializer : DropCreateDatabaseIfModelChanges<MyContext> { protected override void Seed(MyContext context) { context.Database.ExecuteSqlCommand("DBCC CHECKIDENT ('Account', RESEED, 1000000)"); } } Then call from the Application_Start

Two of the class properties have the following annotations: [Key] [Column] [Required] [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } [MaxLength(25)] public string Name { get; set; } I understand that testing Key, Column and Required attributes is no longer a unit test, it's an integration test as it would depend on the underlying database, but how do you go about testing MaxLength(25) attribute? One of the alternatives that I can think of, is to add a code contract into the property. Update As suggested, I wrote the following helper: public class
