I know the unobtrusive client validation is required using Html.XXXFor to generate the input html. But in my project, I want to use Html.TextBox(), and also want to use unobtrusive client validation. I think you'd better expose a extension method like Html.TextBox(..., ModelMetadata,... ) allow me pass the ModelMetadata manually.

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
View 10 RepliesJust found out this problem. Upgraded by site to jQuery 1.5.1. I had some cascading dropdowns populating via some very simple code like this:
[Code]....
This code no longer runs with jQuery 1.5.1 AND unobtrusive validation active. Fails also with jquery 1.5.0. Works fine with jquery 1.4.4.
Why is it that client validation is getting triggered saying that my Default Theme field is required even if I didn't specify a [Required] attribute in my model?
public class Site
{
public int SiteId { get; set; }
Required(ErrorMessage = "*")]
[LocalizedDisplayName("Title")]
public string Title { get; set; }
[Required(ErrorMessage = "*")]
[LocalizedDisplayName("RootDirectory")]

I'm trying to implement client validation for my custom type, however i'm not sure how to do it for min/max validators.
[MultilanguagePropertyRequired(ErrorMessageResourceName = "fld_Description_val_Required", ErrorMessageResourceType = typeof(Resources.Service.Controllers.Firm))]
[MultilanguagePropertyStringLength(1000, MinimumLength = 150, ErrorMessageResourceName = "fld_Description_val_MinLength_lbl", ErrorMessageResourceType = typeof(Resources.Service.Controllers.Firm))]
[Display(Name = "fld_Description_lbl", ResourceType = typeof(Resources.Service.Controllers.Firm))]
public MultilanguageProperty<string> Description
[code]...
The default validation in MVC 3 is based on jQuery Validation, which I can usually customize with something like:
$.validator.setDefaults({
submitHandler: function() { alert('submitHandler'); },
errorPlacement: function(error, element) {
// do something important here
alert('errorPlacement');
},
errorClass: "error",
errorElement: "input",
onkeyup: false,
onclick: false
})
I'm using the latest RC with asp.net mvc 3, and have turned on unobtrusive javascript validation and added the necessary scripts to the page. All of the validation works perfectly, but when I try to submit the page, it simply doesn't post. If I turn unobtrusive javascript off in the web.config without making any other changes, everything works perfectly fine.
Here's my scripts I'm using:
<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
Is it possible to validate a form that has been loaded dynamically by Ajax? I have two forms that I load on a page with another form and niether of the Ajax forms can be validated.
View 14 RepliesFor some reason fields named with '.value' or .anything does not generate client validation. For example this code:
@Html.TextArea("ContentObjectFirm.Description")
generates this:
<textarea rows="2" name="ContentObjectFirm.Description" id="ContentObjectFirm_Description" data-val-required="Firm description is required" data-val="true" cols="20">
I am new to ASP.Net MVC 3, facing some issues while trying to implementing client side unobtrusive validation for a editor template I have created for showing date in

[Code]...
I have a form where one of the fields would allow entry of HTML tags.
<asp:TextBox ID="someID" runat="server" TextMode="MultiLine" />
In this field I have a RequiredFieldValidator validation only. Unfortunately, after any PostBack if the content of any of the fields includes HTML tags or any other potentially dangerous code - the entire ViewState is cleaned.Setting ValidateRequest to false does not help. I'm using IIS 7.5 and .NET 4.0.
My team members don's support the use of validation controls that are available in asp.net (for web application).
What are arguments in favor of validators instead of or in addition to javascript validation?
I make a partialView based "Detail-Edit" function as : 1 create two partial view : Details , Edit
2 in Details PartialView I render a link as "Ajax.ActionLink( .. "Edit" , AjaxOptions { get , updateTargetId="xx" , InsertMode="Replace" } )
3 in Edit PartialView I use "Ajax.BeginForm()" ...
As a result I can perfectly swith from Details view to Edit view in ajax manner ; however when I change to Edit mode in this approach, the "obtrusive js validation" loses its function that it can't prevent user from callback ajax even with invalid inputs. I think this is a common issue for MVC3 developers, could anyone help to give a standardized solution against this ? or any other valuable solutions ?In a word, just want to realize the traditional UpdatePanel-based "Edit,Details" effect on MVC mode with ajax .
I'm trying to add a validation support to DropDownList by creating a custom control inheriting from DropDownList:
public class MyDropDown: DropDownList, INamingContainer
{
private const string ValidatorID = "Validator";
private RequiredFieldValidator _validator;
[Code]....
My class implements INamingContainer because I wanted to avoid naming conflicts. Unfortunately when I try using this control I get the following exception:
Unable to find control id 'MDD' referenced by the 'ControlToValidate' property of 'MDD_Validator'
This is happening beause for INamingContainer FindControl(NamingContainerId) returns null.
When I remove INamingContainer implementation and set validator ID in the following way:
_validator.ID = String.Format("{0}_{1}", ID, ValidatorID);
Everything is working fine, and id given to Validator is the same as it would be inside Naming container.
But is there a way to accomplish this WITH INamingContainer ?
i'm working on a MVC3 webapp and my Model consist of many classes that use a custom type (TextRef) for textual properties. for example my Product entity looks like :
[Code]....
TextRef :

so in my views i'm using :
[Code]....
how could i add validation support to TextRef items ? for example making Product.Title required
Let's say that I have the following HTML for a text box on an ASP.NET page:
<div class="myClass">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
It is easy enough to add a required field validator to this page like this.
<asp:RequiredFieldValidator ID="valMyTextBox" runat="server" ControlToValidate="txtMyTextBox" ErrorMessage="My Text Box is required."></asp:RequiredFieldValidator>
But I need to modify the HTML slightly if this text box fails validation. I need to add a CSS class to the DIV. So if the user leaves this field blank I need the HTML to look like this:
<div class="myClass error">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
Is this possible? I can't figure out if there is a way to write code behind that only fires if this particular validator control fails validation or something. I know I can write code that runs when the entire page is not valid. But I just want this code to run when this validator returns invalid. Hope this makes sense.

View 1 RepliesI'm using 3 text boxes for allowing user selecting different ranges. I want to perform below validations on three text boxes.
1.User should enter a value (i.e. a valid number,doesn't allow to enter zero,decimal numbers and negative numbers) in 1st text box.
2. 2nd text box value should be greater than 1st text box.
3. 3rd text box value should be greater than 2nd text box.
I want to perform validations on client side only using JavaScript. If anything goes wrong I want to populate a message box.
I have TextBox1 (enabled = true) and TextBox2 (enabled = false) in my WebForm on loading. Both are validated by means of a RegularExpressionValidator.
How can I set TextBox2 enabled = true ONLY AFTER (!) the text inserted in TextBox1 has been validated and accepted as valid ?
Can this be done on client side exclusively or is some code behind absolutely necessary ?
