How to Create Two Different Form Controls and Merge Them in Angular

When working with Angular, you may come across a situation where you need to create two different form controls and then merge them together. This can be useful when you want to combine the functionality of multiple form controls into a single form element. In this blog post, we will explore two different solutions to achieve this in Angular.

Solution 1: Using FormGroup

The first solution involves using the FormGroup class provided by Angular. This class allows you to group multiple form controls together. Here’s an example:

import { Component } from '@angular/core';
import { FormGroup, FormControl } from '@angular/forms';

@Component({
  selector: 'app-form',
  template: `
    

      
      
    
  `
})
export class FormComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      control1: new FormControl(),
      control2: new FormControl()
    });
  }
}

In the above code, we create a FormGroup instance called myForm and add two form controls, control1 and control2. The formControlName directive is used to bind the form controls to the respective input elements.

Solution 2: Using ngModelGroup

The second solution involves using the ngModelGroup directive provided by Angular. This directive allows you to group multiple form controls together. Here’s an example:

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

@Component({
  selector: 'app-form',
  template: `
    

      

        
      
      

        
      
    
  `
})
export class FormComponent {
  control1: string;
  control2: string;
}

In the above code, we use the ngModelGroup directive to group the form controls. The [(ngModel)] directive is used to bind the form controls to the respective input elements. The values of control1 and control2 can be accessed in the component class.

Both solutions achieve the same result of merging two different form controls together. Choose the solution that best fits your needs and coding style.

That’s it! You now know how to create two different form controls and merge them in Angular. Happy coding!
