Validator Toolkit for ASP.NET MVC

Created Issue: Multiple ValidateScriptMethod on same element fails

To fix, remove the duplicate type checking in ValidationSet, which seems redundant.

Commented Issue: Regular Expression Validator

leppie — Fri, 04 Jul 2008 07:49:08 GMT

Attached is a regular expression validator (named ValidatPattern) that validates a control against any regular expression. You have the option of passing 2 different regular expressions (one for client side and one for server side) to account for any variations in javascript and .NET regular expression parsing.

I am new to using this library, so I would appreciate if someone could take a look at this and make sure it implements the pattern correctly. I hope this helps add to the use and success of this project.

Seems the CodePlex people was absent with the usability seminar. The .cs file is the last one, and working for multiple patterns on a page.

Here is a fixed version. the Pattern vars are now suffixed with a number.

This is broken, it only accept 1 ValidatePattern per page.

New Post: Asp.Net MVC Preview 3 Support

Toolkit works with ASP.NET Preview Release 3

Project Description

The Validator Toolkit provides a set of validators for the new ASP.NET MVC framework to validate HTML forms on the client and server-side using validation sets. By defining a validation set, e.g. a LoginValidationSet class, the toolkit will generate code, in conjunction with the JavaScript library jQuery, to validate on the client-side and will use the same set of rules to validate on the server-side.

Basically, you will create a validation set class which derives from ValidationSet base class:

public class LoginValidationSet : ValidationSet
{
	string Username = "";
	string Password = "";
 
	protected override ValidatorCollection GetValidators()
	{
		return new ValidatorCollection
		(
			new ValidateElement("username") { Required = true, MinLength = 5, MaxLength = 10 },
			new ValidateElement("password") { Required = true, MinLength = 3, MaxLength = 10 }
		);
	}
 
	protected override void OnValidate()
	{
		if(Username == "Bill" && Password == "Jobs")
			throw new ValidatorException("username", "The username/password combination is not valid");
	}
}

Then, you will attach it to the view and the HTML form processing action using the ValidationSetAttribute:

public void Login()
{
	RenderView("Login");
}
 
[ValidationSet(typeof(LoginValidationSet))]
public void Authenticate()
{
	if(this.ValidateForm())
		RenderView("Ok");
	else
		RenderView("Login");
}
 
...
 
[ValidationSet(typeof(LoginValidationSet))]
public partial class LoginView : ViewPage
{
}

Then, you add the following script and methods to your view:

<script type="text/javascript">
	$(function(){
		updateSettingsForLoginValidationSet($('#loginForm').validate({rules:{

));
});
</script>

...

<form id="loginForm" action="/Authenticate" method="post">
...
</form>

<% this.RenderValidationSetScripts(); %>
}}
This all to validate the login HTML form on the client and server-side.

More documentation take a look at the article on CodeProject.com: http://www.codeproject.com/KB/aspnet/MvcValidatorToolkit.aspx

Please see the source code with the included sample site for more examples. You will also find a multi-form example showing how to use the toolkit in conjunction with multiple forms on one HTML page (view).

New Post: Asp.Net MVC Preview 3 Support

romb — Mon, 16 Jun 2008 13:58:21 GMT

Hi!

Just tried to build with Asp.Net MVC Preview 3 (Needed to change references and RenderView() to View()).
But launching web-project failed - nothing happens. Even no exceptions occurred.
Seems some change in the source required to use the latest Asp.Net MVC Preview.

Also I might have made some mistakes while migrating the project.

Please let me know if the migration is possible without modifications in the Toolkit.
Or when the new version is released :) - want to see the Toolkit in action :)

Thanks,
Roman

COMMENTED ISSUE: Crash on RenderClientScript when ViewData is assigned

JokerLash — Wed, 16 Apr 2008 10:00:02 GMT

I'm getting a crash on any page that has a ViewData object example assigned to it i.e.:
public partial class SampleView : ViewPage <SampleViewData>
Comments: ** Comment from web user: JokerLash **

I have the same problem. When i tell my View that the ViewData object is of type X using: public partial class SampleView : ViewPage <SampleViewData>

when i call the RenderView("myView", new SampleViewData());
i still get an error stating: 'MvcValidatorToolkit.SampleSite.Controllers.SampleControllerViewData' does not contain a property with the name 'SampleXValidationSet'.

To solve this problem i added a property to my SampleViewData class called SampleValidationSet of type SampleValidationSet
eg:
public class SampleViewData
{
public string Test { get; set; }
public SampleValidationSet SampleValidationSet { get; set; }
}

But i don't think this is an ideal solution, can anyone supply a better one?

COMMENTED ISSUE: Problems with '.' in control name and id

JokerLash — Wed, 16 Apr 2008 08:39:14 GMT

we're using MVC preview 2 with the bindinghelper, which uses the syntax <objecttype>.<attributename> as the id and name for the UI controls.
this causes a problem because the javascripts created with validator toolkit look like
v.settings.rules.<objecttype>.<attributename>
instead of v.settings.rules.controlname
which is obviously not valid.
I was forced to do a dirty hack, replacing '.' with '$' in key names in the ValidationSet.CreateClientScript for rules and messages, which furthermore forced me to update jQuery.Validation.js :-(

do you have any other idea?

thanks in advance,
stefan

I also walked into this problem, on CodeProject someone else posted a different solution to this problem.
