MVC :: Validation Using RegularExpressionAttribute?


I have the following code

[RegularExpression(EmailValidator.Pattern, ErrorMessageResourceName = "Organisation_Email_Invalid", ErrorMessageResourceType = typeof(MyResources))]
public string Email { get; set; }

But the custom error message in the resource file is being ignored. and I get the following message.Email must match the expression ^[a-zA-Z][w.-]*[a-zA-Z0-9]@[a-zA-Z0-9][w.-]*[a-zA-Z0-9].[a-zA-Z][a-zA-Z.]*[a-zA-Z]$.If I set the ErrorMessage in the attribute it works fine but it then cannot use the ResourceFile.The RequiredAttribute Validators are working fine. Is this a known issueor I'm I missing something.

Serious Error Wrt RegularExpressionAttribute On MVC2 RC1?
If I decorate my model with a regular expression + localized string resource, and the ErrorMessageResourceName does not resolve to something on the object, the following things happen:

The regular expression is ignored altogether from a validation perspectiveNo error messages are raised in the MVC application.I would love it if the framework floated an exception in this instance because exclusion of this rule could have far reaching implications.The following is a modification to the ChangePasswordModel.NewPassword property in the stock MVC 2 RC1 project that exhibits the behavior. Note that while the MyResources does exist in my project, the EMResourceName does not exist on it.

[Code]....

[RegularExpression(@"^(?=.*d)(?=.*[a-z])(?=.*[A-Z]).{4,8}$", ErrorMessageResourceType = typeof(MyResources), ErrorMessageResourceName = "InvalidPasswordMessage2")]

MVC :: RegularExpressionAttribute Validator Always Returns False?
I'musing a model which receivessome input from a form and has some validation logic attached via attributes. In one case I'm validating personal names, which should include only letters, apostrophes, spaces and dashes, and be no more than 50 chars long. So I have a modelproperty like:

[Code]....

Everything works fine BUT the RegularExpression attribute: if I add it, I always get a validation error, even when what I type in my form is a valid name (e.g. "Foo"). No matter how I modify the regular expression or what I type, I always get an invalid name error.

(For some reason, I cannot see the regex posted correctly here: it is just ^ followed by the Unicode Letter class and []+ including a Unicode letter class, apostrophe, whitespace and dash, ended by dollar: i.e. start of string - any letter - any of the following: letter, apostrophe, whitespace, dash, 1 or more times; end of string).

What I'm doing wrong here?

How To Extend Server-side Validation Controls To Raise An Event If Validation Fails
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?

Jquery Validation Not Working Throwing Error $.validation Is Undefinedj?
jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.

Is It Possible To Use Validation Controls When I Need To Modify HTML When Validation Fails
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.

Web Forms :: Master Page Validation Effects Content Page Validation?

Then in the content page I have various controls with validation and a validation summary. I have few custom validators on the content page like below:

[Code]....

which uses the clientvalidationsfunctions which set thevalidityof the page.Now when I leave the search box in the header blank and I click the submit btn in the content page it posts me back to same (source) page and while debugging I find that the Page.IsValid is false. But if I write something in the search textbox in the master page and the fill the required fields in the content page and click the submit btn in content page it works fine. Why is that so? My validation groups are different on master page and content page.

How To By-pass Client-side Validation To Verify Server-side Validation
I'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");

JQuery :: Custom Invalid Validation / Using JQuery Plug-in Validation?
Is there a method in jQuery that I can customize an invalid validation myself instead of using jQuery plug-in validation?

For example, if the form is valid do this below.

$('form').validate();
if ($('form').valid()) {
//do something
};

But if I wanted to have a cutomize invalid method I could do this below.

$('form').validate();
if (!x == y) {
$('form').valid() = False; //[:(]
alert('Form is not valid.');
};

Making The Container Of A Validation Summary Visible When The Validation Summary Becomes Visible?
I have the following markup. The errorPanel was first only used to show server side exception messages, and works fine like that. Now I'd like to incorporate my validation summary into that same errorPanel.

[code]....

My problem now is that the required validation happens client side, and I want to keep that, so I have no server side opportunity to make errorPanel visible, in order to make the validation summary visible.

I see I have two options: Do validation server side, and use my code there to make the panel visible, or hook into the client side code somehow and catch an event there when the summary should be made visible, and then also make the errorPanel visible. How could I go about the latter?

with above code it displays the name correctly as "Hide & Seek", but the link generated reads as "Hide_%26_Seek".

First, the link is always shows %26 and not "&".

Second, Upon clicking the link it shows the following error.

MVC :: Are There Any Validation Alternatives
Im looking for some input on a validation problem i have. My demands for validation are:

1. Able to do database checks

2. Error messages are custom and imported from other localized source as stringvariables(NOT resource files).

3. DRY serverside and clientside validation.

As far as ive seen data annotations dont work well under these cirumstances, custom attributes are needed just to be able to output the strings(wonder why this wasnt thought of). This isnt a dealbreaker but as ive tested sofar custom attributes must be added in the global.asax wich i 1. cannot get to work in the CMS im building this on and 2. i dont want to have to edit the global.asax everytime the scripts are implemented. Serverside this solution works fine though. From what ive read IDataErrorInfo should not be used? So havent really checked how to get this rolling with client-side either.

My thought was using custom service layer validation with xval but documentation is very poor to the extent i could find any(couldnt find any real nfo on how to implement xval with your own code, ie not using the autgened client-side metadata wich leads to the annotation problem described above). So i have a hard time finding any working solution other than to build something 100% custom.

Do anyone have a solution or perhaps some information or can steer me in any direction on the best way to getting this done in a good fashion other than building custom?
