I was just wondering why the Range validation attribute can take a Type and two strings as parameters? Is this for validating strings against an Enum or something like this? Also what I am trying to do is find an easy way to validate a 3 character string which must be present in an enum, any sugestions? Thanks, Alex. I did find the Range ctor you mentioned fishy. Couldn't help but investigate. (So I wrote this answer like a log while investigating.) From MSDN public RangeAttribute( Type type, string minimum, string maximum ) Note : MSDN says the Type should be IComparable . And, their example

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 question is: Is there a way to receive the name with spaces which one I configured in DisplayAttribute

The ReadOnly attribute does not seem to be in MVC 4. The Editable(false) attribute does not work the way I would want it to. Is there something similar that works? If not then how can I make my own ReadOnly attribute that would work like this: public class aModel { [ReadOnly(true)] or just [ReadOnly] string aProperty {get; set;} } so I can put this: @Html.TextBoxFor(x=> x.aProperty) instead of this ( which does work ): @Html.TextBoxFor(x=> x.aProperty , new { @readonly="readonly"}) or this ( which does work but values are not submitted ): @Html.TextBoxFor(x=> x.aProperty , new { disabled=

I had the following code: [Required(ErrorMessage = MessageModel.translateMessage("required")))] [Display(Name= MessageModel.translateMessage("id"))] public string user_id { get; set; } I am trying to make the error message dynamic but I get error when compiled.: "An attribute argument must be a constant expression , typeof expression or array creation expression of an attribute parameter type." Any solution for this issue? First you create a Resource .resx file this will contain your localised strings. When you declare the attribute you set the ResourceType argument. This causes the Name,

This question has to have been asked before, but I think the search terms are too generic for me to find the answer I'm looking for, so I'll ask it again. I have a model with an int property, and a range annotation. If the user enters something other than an int, the validation message responds with The value '<bad data>' is not valid for '<property name>' ... which is great, but I want to provide a bit more feedback, i.e., Expecting an integer value in this field. . Since this validation fails before the other validators take a look, I don't know how (or if it's possible) to override the

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.GrossFee)%> Any ideas regarding this will be highly appreciated. Thanks! Instead of the Html.TextBoxFor
