data-annotations

问题 Let's assume that I have two simple classes: public class CustomerDetails { [Required] public string Address { get; set; } } public class Customer { public Customer() { Details = new CustomerDetails(); } [Required] public string Name { get; set; } public CustomerDetails Details { get; private set; } } When I try to manually validate Customer class in a Console application in this way: var customer = new Customer() { Name = "Conrad" }; var context = new ValidationContext(customer, null, null);

问题 In my ViewModels I use several DataAnnotations to validate the form data, there are usually 2-3 annotations per field. For example a field for an email address might look like this: [Required(ErrorMessage = "Please enter an email address.")] [Email(ErrorMessage = "That is not a valid email address.")] // Custom public string Email { get; set; } Now if someone were to submit the form, both errors would show up in the validation summary. Is there any easy way to specify an order to run the

问题 I have this Enum (Notebook.cs): public enum Notebook : byte { [Display(Name = "Notebook HP")] NotebookHP, [Display(Name = "Notebook Dell")] NotebookDell } Also this property in my class (TIDepartment.cs): public Notebook Notebook { get; set; } It's working perfectly, I just have one "problem": I created an EnumDDLFor and it's showing the name I setted in DisplayAttribute, with spaces, but the object doesn't receive that name in DisplayAttribute, receives the Enum name (what is correct), so my

问题 I am working on an MVC2 appication. I use data annotations to validate data (both client side and server side). I have several fields in my model that only allows decimal values. As soon as a user types a decimal values I want it to be converted to comma seperated more readable format. For instance 1200 should be formatted to 1,200 while 500 should stay as it is. Here is my model: public virtual GrossFee? Fee { get; set; } And here is how it is on the view: %: Html.TextBoxFor(model => model

问题 I would like to intercept the "<" character in the form field by a regex validator. I will describe the problem in 3 steps: Step 1 : When I try to submit a form with a field containing the "<" character, I get the "Potentially dangerous request..." - as expected in ASP.NET. Step 2 : To avoid ASP.NET's RequestValidation, I decorate my Update method in the controller with "[ValidateInput(false)]". It works as expected - now I can post "<" character without error. Step 3 : I use xVal with

问题 Maybe it's just the way my mind works, but I have a very hard time understanding how you're supposed to do custom unobtrusive validators. The C# part is easy enough, but the jqueryui adapters are where i get lost. I've been trying to make a validator that requires a date to be a certain amount of time in the past. I use this for age validation, to make sure someone has entered a date that is 18 years in the past. I finally decided to just make it a remote validator, that way the validation

问题 I have a class with [Display(Name ="name")] set in the properties, and [Table("tableName"] in the top of the class. Now I'm using reflection to get some information of this class and I'm wondering if somehow I can add a [Display(Name ="name")] to the class itself. It will be something like [Table("MyObjectTable")] [Display(Name ="My Class Name")] <-------------- New Annotation public class MyObject { [Required] public int Id { get; set; } [Display(Name="My Property Name")] public string

问题 I have the following code working [Required(ErrorMessage = "Price is required.")] [Range(typeof(Decimal), "1", "9999", ErrorMessage = "Price xx.xx")] public decimal? productPrice { get; set; } When the page is submitted with Price = EMPTY Field error message is "Price is required.". Price = over 9999 error message is "Price xx.xx". However, when I type 'aaaa' the error message is "The field productPrice must be a number." How can I change the message if type in not correct? Like : "Price must

问题 I have been using mvc2 for a while now, and when i need to set the template i use the DataType Attribute [DataType("DropDown")] public int Field { get; set; } I see others using UiHint to achieve the same results [UiHint("DropDown")] public int Field { get; set; } What is the difference between using these two attributes? Which attribute should I be normally using, or are they for different tasks? 回答1: DataType is generally used to make it known that this is a very specific version of a

问题 I have ASP.NET MVC (4) project which localization is supported by the framework. Should I change browser settings to another language, framework automatically picks up the right resource file. However, because I am using knockoutjs I fall back to jQuery validation at those views. Unfortunately there's no automatic support for localization there. My question is - what are the best practices and ways to customize and localize jQuery validation messages so they will be picked automatically
