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

For 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

I'm using a CustomValidator control to validate some controls in a GridView. I have the validation working perfectly on the client and the server, but would ideally like to pass the GridView ID into the client function so I can move it out into a separate
.js file. The signature for my client function is:
function valOrder_ClientValidate(source, args) { // Code here}
And my CustomValidator control looks like:

Is there a way I can pass an additional parameter into this function?
Just 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

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 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.
View 5 RepliesI'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 RepliesI'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.
View 2 RepliesI write a class inherited from ValidationAttribute such as
[//...]
public class MyValidation:ValidationAttribute
{
//...
}
but when I use MyValidation,and EnableClientValidation,I found that it would not create client script automatically .
Defined RegisterModel class - with some validation rules for creating new users, and this works fine.
Then I get this class, strip few properties and wanted to reuse it as UserInfo_Form_Model, for editing user properites.
No changes, just deleted few items, renamed and reused in strongly typed View for editing.
And result of validation is: -
[DisplayName("Name")] works fine, showing correct
[StringLength(20, ErrorMessage = "xxxx...")] - not working, no message showed when suppose to be one
[Required(ErrorMessage = "xxxx.")] - not working, not showing messages when delete required values?
but (ModelState.IsValid) is false when I checked it in controller (it had to be because required value is missing)?
Is it this only partially correct and how this can be?
Well this is a bit frustrating because it cant be simpler than this and I cant make this simple code reuse.

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?
View 1 RepliesI'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires:
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
This is how I've manipulated some of the page contents (this just prevents submission):
mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2;
string html = doc.body.innerHTML;
html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true");
doc.body.innerHTML = html.ToString();
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
I want my Start Time and End TIme should not be equal to each other and I want the End TIme should not go beyond the Start TIme. For example:
Start Time = 8:30 AM
End Time = 8:00 AM
The above example should have an error because the End Time go beyond the Start Time.
My HTML code:
Time In:
<cc1:MaskedEditValidator ID="mevStartTime" runat="server" ControlExtender="meeStartTime"
ControlToValidate="txtStartTime" IsValidEmpty="False" EmptyValueMessage="Time is required "
InvalidValueMessage="Time is invalid" Display="Dynamic" EmptyValueBlurredText="Time is required "
InvalidValueBlurredMessage="Invalid Time" ValidationGroup="MKE" ForeColor="Red" />
<asp:TextBox ID="txtStartTime" runat="server" Text='<%# Bind("StartTime", "{0:t}") %>'
[Code] ...
Time Out:
<cc1:MaskedEditValidator ID="MaskedEditValidator1" runat="server" ControlExtender="meeStartTime"
ControlToValidate="txtEndTime" IsValidEmpty="False" EmptyValueMessage="Time is required "
InvalidValueMessage="Time is invalid" Display="Dynamic" EmptyValueBlurredText="Time is required "
InvalidValueBlurredMessage="Invalid Time" ValidationGroup="MKE" ForeColor="Red" />
<asp:TextBox ID="txtEndTime" runat="server" Text='<%# Bind("StartTime", "{0:t}") %>'
[Code] .....
If I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
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?
