MvcValidatorToolkit

This project is not maintained anymore.

The Validator Toolkit provides a set of validators for the ASP.NET MVC framework to validate HTML forms on the client and server-side using validation sets.

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

See also my homepage on Parago.de: http://www.parago.de

More Screenshots here on this page.

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))](ValidationSet(typeof(LoginValidationSet)))
public void Authenticate()
{
	if(this.ValidateForm())
		RenderView("Ok");
	else
		RenderView("Login");
}

//...

[ValidationSet(typeof(LoginValidationSet))](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 is all to validate the login HTML form on the client and server-side.

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).
