I'm having problems trying to get the unobtrusive jquery validation to work with a partial view that is loaded dynamically through an AJAX call. I've been spending days trying to get this code to work with no luck. Here's the View: @model MvcApplication2.Models.test @using (Html.BeginForm()) { @Html.ValidationSummary(true); <div id="res"></div> <input id="submit" type="submit" value="submit" /> } The Partial View: @model MvcApplication2.Models.test @Html.TextAreaFor(m => m.MyProperty); @Html.ValidationMessageFor(m => m.MyProperty); <script type="text/javascript" > $.validator.unobtrusive.parse

RequiredAttribute with AllowEmptyString=true in ASP.NET MVC 3 unobtrusive validation

阅读更多关于 RequiredAttribute with AllowEmptyString=true in ASP.NET MVC 3 unobtrusive validation

问题 If i have [Required(AllowEmptyStrings = true)] declaration in my view model the validation is always triggered on empty inputs. I found the article which explains why it happens. Do you know if there is a fix available? If not, how do you handle it? 回答1: Note: I'm assuming you have AllowEmptyStrings = true because you're also using your view model outside of a web scenario; otherwise it doesn't seem like there's much of a point to having a Required attribute that allows empty strings in a web

问题 Ok, here is the deal, I have seen a few posts on SO relating to this issue, but nothing is working for me. Basically, I have select drop downs that are being loaded from partial views, I am trying to filter contents of each subsequent drop down, based on the previously selected drop down. If I just put the call to the partial view in the div containers, and load the page, the validation from data annotations works fine, primarily Required attribute . However, if I try to load the same partial

Unobtrusive validation in Chrome won't validate with dd/mm/yyyy

阅读更多关于 Unobtrusive validation in Chrome won't validate with dd/mm/yyyy

I'm trying to use the simplest possible scenario using a date picker in different browsers. I suspect I'm doing something very simple the wrong way but after lots of searching around I still haven't found a solution. Below is some sample code that represents what I'm attempting. If I use Chrome (v12.0.742.122) and pick a date from the picker like 13/08/2011 the jQuery validation logic will not allow the page to submit even though I've explicitly specified the format as 'dd/mm/yy'. If I change the format to 'dd/M/yy' and choose a date like 13/Aug/2011 it works in Chrome but then won't submit

Adding jQuery validator rules to dynamically created elements in ASP

阅读更多关于 Adding jQuery validator rules to dynamically created elements in ASP

问题 I've got some dynamically inserted form fields on a page in an MVC3 project. Normally we would add the jQuery validation server-side, but in this case we can't (multiple fields in the UI generate the value for one hidden field - and this is what is submitted. We can't validate against a hidden field, so we must instead add UI-only validation for the fields the user can see) Once the fields are dynamically added to the page, I run the following code over the container: $container.find(".date")

Best Practices ViewModel Validation in ASP.NET MVC

阅读更多关于 Best Practices ViewModel Validation in ASP.NET MVC

问题 I am using DataAnnotations to validate my ViewModel on client side with jquery.validate.unobtrusive and on server side in ASP.NET MVC application. Not so long time ago, I figured out that I can write validation like this: [Required(ErrorMessage = "{0} is required")] public string Name { get; set; } That way I can easily define some general strings in config or in resources and always use it in DataAnnotations . So it will be easier to change validation messages in my whole application in

Manually set unobtrusive validation error on a textbox

阅读更多关于 Manually set unobtrusive validation error on a textbox

问题 I'm doing something similar to the remote validation, except that I already make my calls manually via jquery and setup whatever I had to setup. Now my problem is, if I want to tell the validator that a particular textbox is not valid (and prevents the page from submitting, highlight the textbox, etc). How would I do this from code? @Html.LabelFor(m => Model.Slug) @Html.TextBoxFor(m => Model.Slug) <span id="UrlMsg" class="field-validation-error" style="display: none;"></span> if (error) { $('
