MVC :: Can DataAnnotations Persist Through Serialization
May 24, 2010
I am using business objects that are accessed via webservices. These objects can be loaded via the webservice and serialized to my mvc app. The mvc app can get a web reference to the objects and they can be utilized in the mvc app. However, the business objects are where the classes are defined, and where the annotations are applied.
The mvc validation seems to have no idea that there are System.ComponentModel.DataAnnotations attributes applied to this business object class.
1) Are DataAnnotations lost when objects are serialized / deserialized?
2) If in mvc I use a view model approach, and have nested objects (which themselves have public properties - decorated with DataAnnotations) can/will the mvc validation system traverse the entire object model, the model being used for my view? (so it can see DataAnnotations attributes of the nested object)?

I'm building an MVC 2 application with a MySQL database behind it. I've imported the model by adding an ADO.NET Entety Datamodel. Now I want to use DataAnnotations to validate the user input. So I have added the line
[Code]....
[code]....
However, It just doesn't do anything. The Model.IsValid() returns true no matter how long a string I submit.

I am using Entity Framework with partial classes added on so I can use DataAnnotation attributes. Does anyone know how to add a data annotatin which will verify that a field is a whole number (or a DataType of int or long)? I'm surprised there is no [DataType(DataType.Integer)] attribute. I tried to create a custom attribute, but it doesn't work because the value it receives is always null:
[code]....
Obviously I'm missing the point, but I don't know enough to know what I'm missing.

I have a DateTime property in my model and I would like to validate it using DataAnnotations.In my view I want to get that DateTime as a number of days (e.g. "3"), instead of a DateTime (e.g. "7/14/2010"). If user enters "3" in the view, then DataAnnotation finds it invalid -and that is the issue.What are my options in this scenario?

I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great.If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.

I have a few field in my entity that i wish to be non-editable. Looking in the docs it seems like "EditableAttribute" would do the trick. However this is only 4.0Just wondering if there are other attributes that would have the desire effect. So be clear, i have a field called "DateRegistered" i wish to display this as string not text field using "Html.EditorFor"

I have a problem with server-side validation in xVal. I'm using the RequiredAttribute from DataAnnotations.
I would like to change error message from:
The field is required.
to:
Polje je obvezno.
My current solution is this: [Required(ErrorMessage = "Polje je obvezno.")]
But I was wondering if it's possible just to write [Required] and to override error message in one place? (like there is a localization file for client-side validation in xVal)

Is it possible to add a CSS class from DataAnnotations (metadata) when I use Html.EditorForModel() - without a custom template...
Something like this [DataType(CssClass = "DateTime")]
public class TestInput
{
[Required(ErrorMessage = "Name is required.")]
public string Name { get; set; }
[Required, StringLength(500)]
[DataType(DataType.MultilineText)]
public string Description { get; set; }
[Required]
[DataType(CssClass = "DateTime")]
public DateTime Date { get; set; }
[HiddenInput(DisplayValue = false)]
public int Id { get; set; }
}
Here is a link to what I am referring to: [URL]

I'm having problems with getting my custom dataannotations to work, I'm trying to add a validation-attribute that validates that the UsergroupName for a Customer (CustomerID) is unique.
[Code]....
the IsValid should return false if the "count >0". How do I fix this one so it works. GetUsergroups() returns IQueryable<Usergroup>.

I have tried everything to get client-side validation to work in MVC2 RC, but have been completely unsuccessful. Server-side validation works just fine, but client-side never fires. I have grabbed
[Code]....
from the futures source, since it wasn't included in RC. Unfortunately, that's the only script that people agree is necessary for everything to work. Besides that, nobody seems to know which other specific js scripts are needed. The candidates are (jquery-1.3.2.js, jquery.validate.js, MicrosoftMvcAjax.js, MicrosoftMvcJQueryValidation.js). I've tried every permutation of these and other scripts to no avail.
Html.EnableClientValidation() has been included before BeginForm, and the JSON validation data appears to be correctly written into the source of the page. But, again, client-side validation never fires.

I'm using DataAnnotations in my viewmodel class:
[Code]....
In my view I enabled client-side validation.
[Code]....
So, is this the way it's supposed to work? Shouldn't enabling client-side validation highlight non-validating elements by default, without an needing to create an associated Html.ValidationMessageFor(), if it has a DataAnnotation validation attribute?

I'm building an application using MVC 3 and Entity Framework 4. I've created my Entity Data Model and generated a database from it. Now I know the validation attributes such as [Required] or [StringLength(5)] can be used on the model properties to provide validation both clientside and serverside.
I would like to know if these attributes can also be generated dynamically instead of having to add them to the model explicitly? I saw that in EF 4.1 RC you can make use of the Fluent API to further configure your model in the OnModelCreating method by using the DbModelBuilder class. As shown here I'm working with a framework however that still uses ObjectContext instead of DbContext so I would like to know if the above solution can be used in combination with ObjectContext?
As a final note, since I've been trying to figure out how to generate and use data annotations it seems using view models would increase the complexity of validation. From what I read here it seems that just passing the models directly to the view would remove the need to add annotations to the models as well as the view models. However that means that you can no longer use strongly typed views when you do joins on the models and pass those to the view directly?

My case:I am developing an application that will run for multiple clients, each client has the ability to customize field displays and error messages.My issue:I created some custom attributes which inherit from DisplayNameAttribute, RequiredAttribute etc... and in them I am pulling out the resource needed.However it is only executed the once, so if my context changes it will be pulling the incorrectly cached value instead of pulling the new value need.Has anybody attempted to try something like this with the data annotations? Or any advice such as just don't use them for this scenario?

I'm trying some WCF ajax.net 3.5 out for the first time, and I'm having some difficulties. I have a WCF Service which I have connected to in my aspx page using <asp:ScriptManager>. I have a custom object which has been decorated as a [DataContract]. I'm calling the object from javascript successfully, I can see the JSON response in FireBug, but Sys.Serialization.JavaScriptSerializer.deserialize() chokes on it. I'm sure I'm making a noob mistake, but I used up all my patience getting the Web.Config values right for running the WCF service.
Here's a mockup of what I'm doing.

Why this WCF 3.5 method
[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Json
{
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public string Upper(string text)
{
return text.ToUpper();
}
}
returns {"d":"TEXT"} ?
It should returns {"TEXT"}
I'm calling using jQuery.
$("#upper").click(function() {
$.ajax({
type: "GET",
url: "/Json.svc/Upper?text="+$("#input1").val(),
success: function(data) {
$("#input1").val(data.d);
}
});

I'm using DataAnnotations to validate creation of a new Admin user. However on EDIT page I want to have password and confirm password fields blank. This way i know that password has not changed. However whenever I EDIT a user I get ModelState.IsValid = false because password and confirm password are blank even though I set these in my controller. how would i fix this so that on EDIT screen I can omit "Required" validation?

Summary: DataAnnotation's automatic handling of an "int?" is making me rethink using them at all.Maybe I'm missing something and an easy fix but I can't get DataAnnotations to cooperate. I have a public property with my own custom validation attribute:
[MustBeNumeric(ErrorMessage = "Must be a number")]
public int? Weight { get; set; }
The point of the custom validation attribute is do a quick check to see if the input is numeric and display an appropriate error message. The problem is that when DataAnnotations tries to bind a string to the int? is automatically doesn't validate and displays a "The value 'asdf' is not valid for Weight."For the life of me I can't get DataAnnotations to stop handling that so I can take care of it in my custom attribute.This seems like it would be a popular scenario (to validate that the input in numeric) and I'm guessing there's an easy solution but I didn't find it anywhere.

but if i add in this class System.ComponentModel.DataAnnotations then, Association could not be found.

I'm using DataAnnotations as well as server-side validation logic.
Is there a way to show DataAnnotation's client-side validation errors in the ValidationSummary, as it shows when returning from server validation?
I know I can use ValidateMessage and ValidateMessageFor next to elements, but the spacial design of the form I'm working with doesn't allow for anything other than highlighting the HTML element, however, I would still like to have a message saying what's wrong.
If I place ValidateFor's alongside ValidationSummary in order to mimic a ValidationSummary during client-side validation, they both appear when returning from a failed server side validation.

Split off from http://forums.asp.net/t/1654957.aspx/1?Validation+in+MVC+using+JQUERY+OR+JAVASCRIPT. Start new questions in a new thread.
Hey thanks a lot!!!
The following link worked fine http://geekswithblogs.net/stun/archive/2010/02/27/asp.net-mvc-client-side-validation-summary-with-jquery-validation-plugin.aspx
However, I am Having one other problem. There are four solutions in my project. All my controllers and Views are declared in the Presentation solution. There are auto-generated class files in the solution named DomainModel. So, my views inherits these auto-generated files from the DomainModel solution. The problem is that I can't modify these auto-generated files by using Data Annotations in there. Hence, cannot accomplish my validation. I tried by creating partial classes but no result. By creating a class file in my Presentation solution and then binding it with the view the validation works fine. But my views are binded with the class files (auto-generated) from the DomainModel.
Can you/anyone help me work it out so, that validation works with those classes without modifying it.
