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 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.
View 1 RepliesI got a Category model and it looks like this
[Code]....
My problem is that when i do a tryupdatemodel it validate the ParentCategory aswell, is it really suppose to do that? How could i avoid this, I tried [Bind(Excluede = "ParentCategory)] in the ActionResult but with no luck. I have looked all over the place with no luck everybody just got the Id problem.
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 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.
I am having a problem with the Client Validation not firing when I have marked a nullable DateTime field as [Required] and the value of the field is null. (It is actually stopping ALL client validation on the page working - not just the DateTime field).
Interestingly enough, once a post back has been done and the error picked up on the server, the client validation starts working.
Also if you set the date to a none null value (see commented out line in the controller) it will also work
I have replicated this behaviour in a small test project (this is deliberately very Noddy - just enough to replicate the problem)
Am I doing something fundamentally wrong or am I looking at coding some sort of work around here? (I realise that a Required nullable field sounds like a bit of a oxymoron, but I wanted to present the user with a blank field which they must then fill, not one pre-populated with an arbitrary date value)

I am currently using the 3-tier Repository pattern in my application. Actually it's the first time for me to implement a design pattern at all! i used to put all my code in the so called now presentation layer.
i want to implement data validation, for example, password should not be more than 10 characters and have to contain special characters. Should i put this code in the data access layer? but my data access layer contains methods that take the DTO as a parameter for example
[Code]....
and the same is for other CRUD operations (DELETE and UPDATE), so implementing such validation on the DAL would make me duplicate the code in each and every method that accepts the DataObject as a paramter. Same holds for the business logic layer where i am using it as a proxy between the presentation and the data access layers.
Eventually it has to use the same Data Objects as parameters. This only leaves me with one option which is to do the validation on the Data Object part. But i think this is not the essence of the respository pattern which states that the Data object class should only be a "container" class with no behavior.
I'm not able to set errorMessage for DataType attribute.
Here is sample code :
[DataType(DataType.Currency, ErrorMessage = "Please enter a number")]
But in the ValidationSummary it is displayed:
The value 'sdf' is not valid for StartPrice. Other attributes like Required, StringLength or Range work fine.
I had to remove validationSummary and display messages with <%= Html.ValidationMessageFor() %> nearby input fileds but it is not the solution.
Is there a way to use DataAnnotations for validation, particulary in MVC, while relying on a custom resource provider ?

it works fine on the server-side but I'd like to make this work on the client side as well, so I created a PasswordAttributeAdapter class

My repositories throw exceptions (System.Exception) when some things go bad and I know this is bad practice.. so i will create a custom exception (DataException). My question is should this custom ex class be in the repository layer or the domain layer? Im thinking it should be in Domain layer where all business objects and repository interfaces live but just want to make sure.

I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck.

View 3 RepliesIs there a method in jQuery that I can customize an invalid validation myself instead of using jQuery plug-in validation?
For example, if the form is valid do this below.
$('form').validate();
if ($('form').valid()) {
//do something
};
But if I wanted to have a cutomize invalid method I could do this below.
$('form').validate();
if (!x == y) {
$('form').valid() = False; //[:(]
alert('Form is not valid.');
};
Just wondering, in an ASP.NET MVC3 environnement with entity framework. Should the Unit of Work point to the service layer or the repository (and then the repository point to the service layer) ?
Ive saw two example:
* One where the unit of work and repository both have an instance to the service layer..
Link: Entity Framework 4 CTP 4 / CTP 5 Generic Repository Pattern and Unit Testable
Doesn't use a service layer but its obvious that one could be use in that case.
* Second where the unit of work have an instance to the repository which have an instance to the service layer..

For validating login field (at register form) I use customValidator

function LoginValidate(oSrc, args) {
var login = $(".loginField").val();[code]....
For successfull validating I should setup args at ClientValidationFunction, but I get result validation only at callBack. So how can I setup args for validation work.

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.
protected void cusCustom_ServerValidate(object sender, ServerValidateEventArgs e)
{
if(e.Value.Length == 8)
.IsValid = true;
else
e.IsValid = false;

<asp:CustomValidator runat="server" id="cusCustom" controltovalidate="txtoedate" onservervalidate="cusCustom_ServerValidate" errormessage="The text must be exactly 8 characters long!" />
I am new to asp.net and I have a problem. When the users insert in a editor for a decimal field something other than numbers, they get an error "Field name" is not a number.

I am not refering necessarily to changing the culture just displaying another message.
