Angular 2 can also design forms which can use two-way binding using the ngModel directive. Let’s see how we can achieve this.

Step 1 − Create a model which is a products model. Create a file called products.ts file.

Step 2 − Place the following code in the file.

export class Product { 
   constructor ( 
      public productid: number, 
      public productname: string 
   ) {  } 
}

This is a simple class which has 2 properties, productid and productname.

Step 3 − Create a product form component called product-form.component.ts component and add the following code −

import { Component } from ''@angular/core'';
import { Product } from ''./products'';

@Component ({
   selector: ''product-form'',
   templateUrl: ''./product-form.component.html''
})

export class ProductFormComponent {
   model = new Product(1,''ProductA'');
}

The following points need to be noted about the above program.

• Create an object of the Product class and add values to the productid and productname.

• Use the templateUrl to specify the location of our product-form.component.html which will render the component.

Step 4 − Create the actual form. Create a file called product-form.component.html and place the following code.

<div class = "container">
   <h1>Product Form</h1>
   <form>
      <div class = "form-group">
         <label for = "productid">ID</label>
         <input type = "text" class = "form-control" id = "productid" required
            [(ngModel)] = "model.productid" name = "id">
      </div>
      
      <div class = "form-group">
         <label for = "name">Name</label>
         <input type = "text" class = "form-control" id = "name"
            [(ngModel)] = "model.productname" name = "name">
      </div>
   </form>
</div>

The following point needs to be noted about the above program.

• The ngModel directive is used to bind the object of the product to the separate elements on the form.

Step 5 − Place the following code in the app.component.ts file.

import { Component } from ''@angular/core'';

@Component ({
   selector: ''my-app'',
   template: ''<product-form></product-form>''
})
export class AppComponent { }

Step 6 − Place the below code in the app.module.ts file

import { NgModule } from ''@angular/core'';
import { BrowserModule } from ''@angular/platform-browser'';
import { AppComponent } from ''./app.component'';
import { FormsModule } from ''@angular/forms'';
import { ProductFormComponent } from ''./product-form.component'';

@NgModule ({
   imports: [ BrowserModule,FormsModule],
   declarations: [ AppComponent,ProductFormComponent],
   bootstrap: [ AppComponent ]
})
export class AppModule { }

Step 7 − Save all the code and run the application using npm. Go to your browser, you will see the following output.
