Dynamic Form Creation Part -5 | Setting Field Validation | dynamic form angular | Angular 9
This is a quick example of how to build a dynamic form with validation in Angular 9 using Reactive Forms. The example is a simple registration form for fill details enter firstname, lastname, gender, etc . All fields are required.
I've setup the form to validate on dirty and touch event. This is implemented with a Required property in the dynamicFormArray that is set to true and false.
Styling of the example is all done with Bootstrap 4.3 CSS.
The registrationform component defines the form fields and validators for the dynamic form using an Angular FormBuilder to create an instance of a FormGroup that is stored in the dynamicForm property. The dynamicForm is then bound to the form in the app template below using the [formGroup] directive.
The form element uses the [formGroup] directive to bind to the registrationForm FormGroup in the registrationform component.
