Overview of this book

The ASP.NET Core 2.0 Framework has been designed to meet all the needs of today’s web developers. It provides better control, support for test-driven development, and cleaner code. Moreover, it’s lightweight and allows you to run apps on Windows, OSX and Linux, making it the most popular web framework with modern day developers. This book takes a unique approach to web development, using real-world examples to guide you through problems with ASP.NET Core 2.0 web applications. It covers Visual Studio 2017- and ASP.NET Core 2.0-specifc changes and provides general MVC development recipes. It explores setting up .NET Core, Visual Studio 2017, Node.js modules, and NuGet. Next, it shows you how to work with Inversion of Control data pattern and caching. We explore everyday ASP.NET Core MVC 2.0 patterns and go beyond it into troubleshooting. Finally, we lead you through migrating, hosting, and deploying your code. By the end of the book, you’ll not only have explored every aspect of ASP.NET Core MVC 2.0, you’ll also have a reference you can keep coming back to whenever you need to get the job done.

Configuring and using validation

In this recipe, you will learn how to configure and use client-side validation with jQuery, and server-side validation with C#.

Getting ready

We will create an ASP.NET Core MVC Web Application template by going to File | New | Project | AspNet Core Web Application.

How to do it...

First of all, let's create a class with validation attributes. These attributes will be used on both the client side and the server side:

public class ProductViewModel
{
  public int Id { get; set; }
  [Required]
  [RegularExpression(@"^[a-zA-Z]{1,40}$",
  ErrorMessage = "The field must be a string")]
  public string Name { get; set; }
  [Required]
  [Range(0.01, double.MaxValue,
  ErrorMessage = "Please enter a positive number")]
  public decimal Price { get; set; }
}

In addition to this, we will create a form in order to post the ProductViewModel. This is the Form version of TagHelpers:

<form asp-controller="Home" asp-action="AddProduct" method="post" asp-antiforgery="true">
...
