Angular 16: Difficulty with Reactive Form Control Reset After Conditional Option Removal
I'm relatively new to this, so bear with me... I'm working on an Angular 16 application using reactive forms, and I encountered an scenario when trying to reset the form controls after dynamically removing an option from a select dropdown based on certain conditions. After removing an option from the dropdown, I expect the corresponding form control to reset to a default value, but it seems to retain the old value instead. Here's a snippet of my code: ```typescript import { Component, OnInit } from '@angular/core'; import { FormBuilder, FormGroup } from '@angular/forms'; @Component({ selector: 'app-my-component', templateUrl: './my-component.component.html', }) export class MyComponent implements OnInit { myForm: FormGroup; options: string[] = ['Option 1', 'Option 2', 'Option 3']; constructor(private fb: FormBuilder) { this.myForm = this.fb.group({ mySelect: [''] }); } ngOnInit() { // Initial setup if necessary } removeOption(option: string) { this.options = this.options.filter(o => o !== option); if (this.myForm.value.mySelect === option) { this.myForm.get('mySelect')?.setValue(''); // Attempting to reset to a blank value } } } ``` In the template, I have: ```html <form [formGroup]='myForm'> <select formControlName='mySelect'> <option *ngFor='let option of options' [value]='option'>{{ option }}</option> </select> <button (click)='removeOption("Option 2")'>Remove Option 2</button> </form> ``` The question is that even after I call `setValue('')`, when I remove "Option 2", if it was previously selected, it doesn't reset the form control as expected and retains its old value. I've also tried using `updateValueAndValidity()` after `setValue`, but that hasn't made a difference either. Has anyone faced a similar scenario or knows how to effectively reset the form control when removing an option dynamically? Am I missing something obvious?
