Prefill form

Prefill form

Note

setValue() sets all form control values at once and requires you to provide values for every form control - if you miss any, it throws an error.

patchValue() updates some or all form controls and ignores missing properties - it only updates the controls that match.

Use setValue() to completely replace all form values, use patchValue() for partial updates.

Instructions

1. Update the TaskForm class:

   task.form.ts

   
   preFillForm() {
       this.form.setValue({
         title: 'Generated Task',
         description: 'Generated Description',
       });
   }

Note

With setValue() if you miss any, it throws an error. Use it when you want to completely replace all form values.
