MVC :: How To Disable ModelState Validation Messages (The Value '' Is Invalid.)
Mar 9, 2010
I'd like to disable ModelState validation messages and keep my data annotation error messages.
When I update model, message "The value '' is invalid." apears in ModelState. I know that I'm trying to assign null to not nullable property, but I have my own validation and message.
I use something like this
[Required(ErrorMessage="Blahblah some error")]
I want user to see my message "Blahblah some error", but not stupid message: The value '' is invalid.

I have used IValidateObject successfully using a strongly typed view using HTML Helpers. When I hand code a view, still using a strongly type view, but no HTML/AJAX helpers, e.g.
[Code]....
Note: I am also handcoding the ajax and validation js.
When I post back to the Controller, even though the model data is correct, the ModelState is always invalid, having delved into the ModelState and found the error, it is always on the Model property where the IValidateObject.Validate is used. If I stop implementing the IValidObject on my model it all works fine, but I lose my IValidObject.Validate validation rules. Is there something I can do about this, what determines and at what point does .NET check validity of the ModelState? Presumably I am missing something that needs to be set on the ModelState and is not happening as I am hand coding the views/js.

I've been working with MVC 2 for awhile and ive done ReturnToAction as well as ValidationSummary - but this is a little different in that my "submit" buttons are controls by javascript/JQuery - i debug the action and it does go into the correct Controller Action but once it passes over RedirecToAction, nothing happens....
My second problem is that my ValidationSummary fails to show - i run a test and when it returns a View when ModelState is invalid - nothing shows up
Is it a problem with my buttons/forms/submit/JQuery?
[Code]....
And the Controller looks like this:
[Code]....
My Services handle things like validation, I pass it the ModelState and a ModelStateDictionary wrapper and add errors - am i adding errors incorrectly?
[Code]....

Got a nullable datetime member on my viewmodel.the moment it hit my controller action, the viewmodel's modelstate allready are invalid (because the member is null).Forgot...how that works? (using MVC2)Basically my viewmodel have a social security number, passport number and passport expiracy date.If the ssn is entered, I want to ignore the two passport related fields, so I made the expiracy date member nullable.
Like all other viewmodels in this app, each model have it's own validation function that will do validation, and in there I add an error that the date is required or not valid (if using passport number). mvc itself should not care about the date at all.I dont want to give the date a default value, because then the date will show when the form loads, and it must be an empty field (unless I already got a date of course.

After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.

I am creating a custom 'control' which is simply made of two html inputs [type=text] but can't figure out how the validation will work on the view end.
I want to treat these 2 inner controls as asingle control so when a error is added to modelstate both of these inputs are highlighted in the view and a single validation message is shown.

I have the following code:
[Code]....
The file is validated using FluentValidation. So if the file is valid (Is CSV and less than 400 KB) then the ModelState is valid.
The problem is that if the ModelState is valid then I need to parse the file and here some errors can occur:
[Code]....
Can this be done?
I mean the ModelState was valid but sudenly it is not valid anymore.

I've implemented a validation through:
foreach (var issue in data.GetRuleViolation())
{
ModelState.AddModelError(issue.PropertyName, issue.ErrorMessage);
}
But at the client side I am not able to take the benefit of ValidationSummary as the call is being made by AJAX. What is the right approach on validation.

This is probably going to end up as a stupid question, but countless research has offered me no results. I know there are different types of errors I want to check for, and when I should be throwing an exception for "exceptional" errors, and that I should create validating functions for input and other checks. My problem is, how do I send an error back to a page when the data entered fails in a separate class?
For Example:
User input entered in Page1.aspx, click calls Submit() in Class.vb Class.vb finds that input is invalid How do I update Page1.aspx label to say "Hey, that is not right".

In ASP.Net, how do I limit validation messages to only one?
Rule: User must put in a number between 0 and 1000.
Current [undesired] Behavior:
User types 1001: validator says "Please put in a non-negative number beneath 1000"
User types -1: validator says "Please put in a non-negative number beneath 1000"
Desired Behavior:
User types 1001: validator says "Please put in a number beneath 1000"
User types -1: validator says "Please put in a non-negative number"
In other words, how can I use two asp:RangeValidators whose disallowed values intersect but only turn on the desired one? I do not want to handle a ServerValidate event on the server.

For example, if you use this attribute in a view model object:
[Required(ErrorMessage = "MyErrorMessage")]
public virtual string Subject { get; set; }
Then the following javascript will become generated (but below I have only copied the relevant part below) into the generated "mvcClientValidationMetadata": "Subject_validationMessage","ValidationRules":[{"ErrorMessage":"MyErrorMessage"
I know how it is possible to localize the messages in server validation, by adding your own localized message value to the ModelState, i.e. with the method 'ModelStateDictionary.AddModelError(key, "MyLocalizedMessage");' where the key can be retrieved as illustrated in the "GetErrors" method in the blog tutorial abot xVal [URL]
However, I have not figured out how to be able to customize the generated javascript, which I want to provide with the same localized validation messages as those that will become displayed when the server validation is executing (e.g. for clients that have disabled javascript).

I have a form that has contact fields, billing address, and shipping address. So if i fill out my contact information ONLY and left billing and shipping address blank then hit submit, the validation for the billing address and shipping address appears. Ok no problem, there is a check in each billing and shipping fields that once click on it copies the address from contact to billing or shipping fields. Everything works except for the validation messages. They are still there. Is there a way to remove the validation message after the textboxes are populated with data?

i am currently working on an asp.net mvc (.net 3.5 sp1) web app, that uses data annotations and client side validation. I would like to have localization enabled, thus i have implemented a localization mechanism for enabling site visitors select the locale they prefer, by overriding the Execute() controller action and setting the CurrentCulture appropriately (i get the culture to change to from the URL route parameters).
I tried implementing my model validation messages localization with no success. What i did was adding two resource files undeer my model App_LocalResoorces folder (one for my locale greek language Validation.el.resx and one for the default english language Validation.el.resx) and set the appropriate file properties ("Access Modifier" to "Public", "Build Action" to "Embedded Resource","CustomTool" to "PublicResXFileCodeGenerator" and "Custom Tool Namespace" to "ModelLocalRes". Then i added a RequiredFieldPrompt" name-value to both the resource files.
Then i tried modify the required validation attribute on my model's name metadata like this:
[Code]....
The problem is that i cannot get the localization working, since the error message gets displayed always for the english default locale, no matter the locale selected from the site visitor.

i have a view model with a property like this one :
[RegularExpression(@"^d+$", ErrorMessageResourceType = typeof(Resources.Validation), ErrorMessageResourceName = "NumberValidationMsg" )]
public int? Number {get; set;}
NumberValidationMsg resource is set to "Only numbers allowed !".
but when I try to enter something like 'test' into Number field on form, ModelState displays the ErrorMessage with content similar to :
"The value 'test' is not valid for Number."
can this message be turned off, customized? (or maybe the best solution would be just to replace int? with string)

How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.

I'm having trouble with the implicit type validation for model properties. The validation/error messages (for numeric fields explicitly) are printed in English (I want them to be printed in Swedish). Does anyone know how to override those messages? Or can I turn of implicit type validation? The error message I'd like to translate/localize is "The field {0} must be a number."

I have the this current design. I use a web service/jquery perform client-side validation and to return 1 of 4 integers. At present I store it in a hidden field but it could be passed directly. I then deploy4 validators that when validated, validate the integer and trigger a custom error message. The ideal scenario I would like to be able to do this with one validator and switch the error message accordingly. On the server side the code could look like this:
[Code]....
As you can see my error messages are held as strings elsewhere which I reference for continuity throughout the project. unformtunately I don't know how to achieve this client-side by calling a javascript function. Sure I could hard code the messages in the javascript file as well, but this would mean that they were held in two places and suseptable to error. It may be an option to return an error message in the web service rather than an integer and trigger if it is blank.
