I am trying to make some sense of this validation stuff in MVC2. I followed various walkthroughs, all them for betas/rcs... and I cant' get anythign to happen. Note: THIS JQUERY - NOT THE MS AJAX STUFF!I have referenced MicrosoftMvcJQueryValidation.js which i got got the mvc2 futures lib.
My model is:
[Code]....
The form bit of my ViewPage<User>:
[Code]....
As far as I can see the only additional thing that is being rendered is this:
[Code]....
Which is interesting/annoying for a few reasons. Firstly all of my annotations appear to have been ignored.Secondly FormId isn't even marked as required, and as this rendered text was taken from a page loaded with a null Model (add mode) the FormId field isn't in the form. Finally, this doesn't even result in any actual validation occuring (on the client side). All the server side validation is working fine.See I am using PasswordFor instead of EditorFor. Because someone at MS testing dropped the ball there. Yes EditorFor renders a password field, but it behaves differently to PasswordFor.. the value of the Password field is sent to the client (set in the value
attribute of the field). Fail.
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?
I would like to know if it's possible to bypass the validation of one property which is using Data Annotations. Since I use the model across multiple pages, there's a check I need in some, but not in others, so I would like it to be ignored.
I make use of validation with data annotations in my model classes. How do I make sure this annotations are not violated when I validate data in my business layer, before sending it to the DAL? I guess I don't want to define the validation rules in two places (model classes and in my BLL-classes)?
If I have a search object with a list of fields, can I, using the System.ComponentModel.DataAnnotations namespace, set it up to validate that at least one of the fields in the search is not null or empty? i.e All the fields are optional but at least one should always be entered.
I'm creating a Asp.Net MVC application and I need help on whether I should chose Data Annotations or Service Layer Validation (e.g. if(Model.Name.Trim().Length == 0)?
I have all the properties of the class Person as required using Data Annotations.
[Code]....
In the View I loop the List like this:
[Code]....
Generated HTML:
[Code]....
Result:
Does not work at all.
Other things I've tried:
Tried using these HTML Helper methods instead:
[Code]....
Generated output:
[Code]....
Result:
Interestingly, when I trigger a validation on the first textbox, it fires simultaneously for all of the textboxes. The rest of the textboxes do not trigger validation at all.
Looking at the generated id and names for the textboxes and their corresponding error text span element, they areall identical.
Anyone figure out how to use Client Validation with Data Annotations with a List in the view data, supporting Model Binding?
Get function as on call of save function and delete function the annotation's entry would be updated in the database.But, The Get function is not drawing the marked annotations on the image.How it would work.?
//[Validator(typeof(MandateValidator))] [MetadataType(typeof(Mandate_Metadata))] public partial class Mandate { public class Mandate_Metadata {.........
I am using MVC 2 with Entity Framework 4 models and MetadataType classes to create annotations that do not vanish everytime my model is generated... I followed Scott's article to create that.It worked fine for simple classes, but when I got to a more complex one, with regular expression and range validations on doubles, it seemed to simply ignore the validation annotations altogether.
Whilst my validation is successful/fine with this control (ValidationMessageFor works) I have been unable to find how to highlight the control when validation fails (e.g. with a TextBoxFor the textbox border goes red if validation fails)
Does anyone know how I can add this behaviour with a custom editor template?
I'm attempting to write a unit tests for an ASP.NET MVC 2 post action that takes a view model as its sole parameter. The view model is decorated with validation attributes such as [Required]. I'd like to test two scenarios. The first scenario is when a valid set of data is passed in (ie, all required properties have values) and a redirect to the list page is returned. The second scenario involves passing in invalid data (eg, when one or more of the Required properties are not set). In this case the same view is returned with error messages.The action signature is as follows:
[HttpPost] public virtual ActionResult Create(NewsViewModel model)
The NewsViewModel class is as follows:
public class NewsViewModel { public Guid Id { get; set; }
i'm using microsoftMvcJqueryValidation and I want to call my own client-side validation function for a particular field with the system so that it fires with the other auto generated client-side validation.
I am using VS2010 RC and i created a buddy class. My problem is that i cant seem to see the option to change the Display name of a column.i only see "displaycolumn" and "displayformat".
I have dropdown values like this : credit card, cheque, cash..etc. here i am showing "div" when iam click on cheque or hiding "div" when iam click on credit card,cash..etc.
i wrote Jquery validations for all controls in my page like this ...
[Code]....
if i select cheque in dropdown the validations should be fire other wise not, but now my page all validations fired when click on submit button?
I've looked all over the web for the best way to organize an ASP.NET MVC2 project. I've only seen examples of people using the default template for MVC2 projects. But is this the best way to organize your project if it is going to contain a large number of files?
We're in the process of building an application that is heavily built around jQuery for UI and ajax using JSON. So, as you can imagine, we will have many custom .js support scripts.
In our solution, we have placed all our support libraries (3rd party and custom) into respective projects. The MVC2 project that is also in the solution is using the default MVC2 template.
In the MVC2 project, the "starting" structure is still pretty much unchanged. Under the Controllers directory, we have each controller AccountController.cs and HomeController.cs (for example). Under the Views directory, we have three subdirectories named Account, Home, and Shared. In the Scripts, directory we have also divided that up with three directories, Account, Home, and Shared. And finally we have the Models directory, that is also divided into Account, Home, and Shared subdirectories.
As you can see we haven't deviated from the basic template that much. But, as we start adding stuff to this, we're realizing how cumbersome this might become when we get upwards to 20 or 30 views and 100 support .js files.
I have a table of products on my page, each product has zero or more colors, the colors are shown as a list beneath the product. After the colors I have a button to add a color. The button will do an ajax call with the parent product id to a controller which will return a JSON object with color information. My problem is where to store the product id in the DOM, should I put it in a hidden field and use jquery in the click event of the "add color" to get to it? What is the best way to do this?
EDIT: The page is initially rendered on the server so I don't want to use jquery to add the id's to the page.
I have various questions about validation using data annotations. I am using the following setup
asp.net mvc 2 entity framework 4 data annotations
Basically, I'm trying to get unique validation working and i'm a little confused. My models are as follows:
public class Buyer { public int Id { get; set; } [Required(ErrorMessage = "The email is required")] public string Email { get; set; } [Required(ErrorMessage= "The name is required")] public string Name { get; set; } } public class Seller { public int Id { get; set; } [Required(ErrorMessage = "The email is required")] public string Email { get; set; } [Required(ErrorMessage= "The name is required")] public string Name { get; set; } }...............................................
