MVC :: Client Validation Not Working For Invalid Data The First Time In 3 With Razor
Mar 2, 2011
I've run across with client-side validation. Firstly I'm assuming that everything is set up properly because client validation is working fine other than this specific scenario. The scenario is that if I have a field with a validation attribute on it then I can clear th field value and client validation won't flag it as an error even though the validation should fail. If, however, I type in something that is invalid then from then on it works correctly. It seems like client validation is missing the clearing of the field if it has not yet generated a validation error. Here's a simple model to demo the issue:
[Code]....
Now assume that I have this as my model instance: new SimpleModel() { Id = 1, Name = "One1", EventTime = DateTime.Now } The model is valid. Now I drop in an edit form generated by the Add View dialog. Again I'm assuming client validation is properly set up because it works except for the very specific scenario given earlier.........................
The client side validation will work sometimes, and other times it will put out a JS error.Webpage error details

The date range validates perfectly during model binding. However, . Looking at the client validation code in MicrosoftMvcValidation.js, it appears that the Sys_Mvc_RangeValidator can only handle numeric ranges
I have in the fact copied the code of Login page in the ASP.NET MVC application template (provided with VS). In the original template, client side validation is working but when I copy all the connected code I get only server side validation (no red fields, post back even if data are incorrect).
public class LogOnModel { [Required] [Display(Name = "User name")] public string UserName { get; set; } [Required] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [code]...
there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully?
My model goes like this
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace PitchPortal.Core { public class DocumentMetadata { //[Required] // public bool visibility { get; set; } [Required,StringLength(10, ErrorMessage = "title is too long")] public string title { get; set; } [Required, StringLength(10, ErrorMessage = "description is too long")] public string description { get; set; } [Required, StringLength(10, ErrorMessage = "summary is too long")] public string summary { get; set; }
Have some problems with client side validation (using RequiredFieldValidator, RegularExpressionValidator, CustomValidator with client side validation logic). It seems that WebForm_DoPostBackWithOptions is not fired or causes unhandled exception that makes the form to do the postback regardless it's valid or not.
I tried using a ValidationSummary, hiding it if javascript is supported:
Every thing works fine on Chrome with disabled javascript on my laptop, but not on my Android phone. The problem is that on the phone Javascript is not disabled, it's enabled, and correctly hides the ValidationSummary, but does not perform client side validation for some reason that i can't understand (no developers tools on Android browser :(( ).This is very frustrating! :(
I'm trying to get a very simple client side validation example to work in ASP.NET MVC 2. I'm using data annotations to set a required property "Surname". When I use the Html.ValidationMessageFor(x => x.Surname) the correct client side validation script is written to the page. But when I use Html.ValidationMessage("Surname") the client side validation is not rendered out until after the page has been posted. Client side validation only starts working after a form post! I can see that the script is updated in the page after a form post. There appears to be a bug in Html.ValidationMessage()?
I have applied some asp validation controls on a page ,but on clicking Save button data is getting saved without throwing any validation . But as I am entering data for the next time and then click save button then it's working.

Is it possible to do client side validation on a detailsview (insert or edit) without using validation controls? I.E. somehow capture the onClientClick event of the autogenerated Insert/Update link buttons to call my javascript function?
I am migrating my application to MVC3 and getting this error message Validation parameter names in unobtrusive client validation rules must start with a lowercase letter and consist of only lowercase letters or digits.How can I ovoid it without going and modifying all my ViewModels
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?
I'd like to implement ajax message box that will gather information from validators on a page when client-side validation fires. Like: I have left some text fields blank then press submit button and appropriate RequiredFieldValidators show messages. I would like my message box shows those messages too. I am looking for appropriate way to hook on validators JS event or something.
I'm using Telerik's RadScheduler Control with WebService Binding.
I've used RadScheduler with Server Side Binding which has an event called "OnTimeSlotCreated" which fires every time when a particular time slot creates so that i can access the time slot and get the control (HtmlTableCell Control) to modify it according to the requirement.
But now i'm binding it from client side through WebService which has no such "onClientTimeSlotCreated" event, also these time slots are not having any identity at client side to access.
I use the oob client side validation from mvc 2 RC. The input field validation errors are working fine. But the validation summary is missing. How to get the validation summary on client side validation?
When i use Validator callout extender and as well both client side java script validation , both are not working at a same time.I use java script code for dynamic checkboxes to be atleast one checkbox must be checked.When i use onclient click only javascript validations are fired, when use onclick function javascript code is not working.
The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test).I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.
The problem is that when I submit a blank form back to the controller, I get redirected to the "its valid" page, meaning that the form passed validation.
