Understanding and using ModelBinding

In this recipe, you will learn how to use ModelBinding. The ModelBinding mechanism lets the developer get/set values of UI elements to a class's properties, and vice versa.

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...

1. Let's see how nested types are handled by ModelBinding:

public class Product
{
  public int Id { get; set; }
  public int Name { get; set; }
  public decimal Price { get; set; }
  public Category Category 
  {
    get;
    set; 
  }
}
public class Category
{
  public int Id {
    get;
    set; 
  }
  public int Name 
  {
    get;
    set;
  }
}
@model R2.Models.Product
<form asp-action="Create" method="post">
  <div class="form-group">
    <label asp-for="Id"></label>
    <input asp-for="Id" class="form-control" />
  </div>
  <div class="form-group">
    <label asp-for="Name"></label&gt...
