In this article I will explain with an example, how to perform
Client Side Password and
Confirm Password validation in
ASP.Net MVC Razor using
Data Annotations and
jQuery.
The
Client Side Password and
Confirm Password validation will be performed using Model class and
Data Annotation attributes.
Configuring Bundles and enabling Client Side Validation
Please refer the following article for complete information on how to configure
Bundles and enable Client Side validation in
ASP.Net MVC project.
Note: By default, the validation done using
Data Annotation attributes is Server Side. And hence to make it work
Client Side, the
Client Side validation must be enabled.
Model
The following Model class consists of two properties Password and
ConfirmPassword. The properties are decorated with the following
Data Annotation attributes for performing validations.
Note: The Data Annotations attributes can be used with the Entity Data Model (EDM), LINQ to SQL, and other data models.
The Required
Data Annotation and the Compare
Data Annotation attributes have been specified with a property Error Message with a string value. As the name suggests, this string value will be displayed to the user when the respective validation fails.
The first parameter of the Compare attribute has been set with the name of the property with which the value needs to be compared i.e. Password.
public class PersonModel
{
[Required(ErrorMessage = "Password is required.")]
public string Password { get; set; }
[Required(ErrorMessage = "Confirmation Password is required.")]
[Compare("Password", ErrorMessage = "Password and Confirmation Password must match.")]
public string ConfirmPassword { get; set; }
}
Controller
The Controller consists of following Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
Action method for handling POST operation
This action method handles the POST operation and when the form is submitted, the object of the PersonModel class is sent to this method.
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(PersonModel person)
{
return View();
}
}
View
HTML Markup
Inside the View, in the very first line the PersonModel class is declared as Model for the View.
The View consists of an
HTML Form which has been created using the
Html.BeginForm method with the following parameters.
ActionName – Name of the Action. In this case the name is Index.
ControllerName – Name of the Controller. In this case the name is Home.
FormMethod – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
Inside the View, the following two
HTML Helper functions are used: -
1.
Html.PasswordFor – Creating a Password
TextBox for the Model property.
2. Html.ValidationMessageFor – Displaying the Validation message for the property.
There is also Submit button which when clicked, the Form gets submitted.
Finally,
jQuery and the
jQuery Validation script bundles are rendered at the end of the Model using the
Scripts.Render function.
@model Email_Validation_MVC.Models.PersonModel
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
@using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
<table>
<tr>
<td>Password</td>
<td>@Html.PasswordFor(m => m.Password)</td>
<td>@Html.ValidationMessageFor(m => m.Password, "", new { @class = "error" })</td>
</tr>
<tr>
<td>Confirm Password</td>
<td>@Html.PasswordFor(m => m.ConfirmPassword)</td>
<td>@Html.ValidationMessageFor(m => m.ConfirmPassword, "", new { @class = "error" })</td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="Submit" /></td>
<td></td>
</tr>
</table>
}
</body>
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/jqueryval")
</html>
