To access an input element from a parent component in Angular, you can use `ViewChild` to get a reference to the child component and then access its input element. Here's a general approach you can follow: 1. **In your child component (the custom input component):** - Use a template reference variable to identify the input element. ```html ``` - In your child component class, use `ViewChild` to get a reference to the input element. ```typescript // child.component.ts import { Component, ViewChild, ElementRef } from '@angular/core'; @Component({ selector: 'app-child', templateUrl: './child.component.html' }) export class ChildComponent { @ViewChild('myInput') myInput: ElementRef; focusOnInput() { this.myInput.nativeElement.focus(); } } ``` 2. **In your parent component:** - Use `ViewChild` again to get a reference to the child component. ```typescript // parent.component.ts import { Component, ViewChild } from '@angular/core'; import { ChildComponent } from './child.component'; @Component({ selector: 'app-parent', template: ` Focus on Child Input ` }) export class ParentComponent { @ViewChild('childComp') childComponent: ChildComponent; focusChildInput() { this.childComponent.focusOnInput(); } } ``` This way, when the button in the parent component is clicked, it calls the `focusChildInput()` method, which in turn calls the `focusOnInput()` method on the child component, focusing on the input element. Remember to adjust the component names and paths according to your project structure. I hope this helps! If you have any further questions or need more details, feel free to ask.

To pass a control to a custom input component in Angular without using the get function, you can directly pass the FormControl instance to the component. This approach simplifies the interaction between your form and the custom input, making the data flow more intuitive and declarative. Here's a general approach on how you might achieve this: Define the Input in Your Custom Component: In your custom input component, define an @Input() property to accept the form control. @Component({ // component metadata }) export class CustomInputComponent { @Input() control: FormControl; } Create the Form in Your Parent Component: In your parent component, create the form with FormControl instances for each field you want to connect to a custom input. export class ParentComponent implements OnInit { myForm: FormGroup; constructor(private fb: FormBuilder) {} ngOnInit() { this.myForm = this.fb.group({ name: new FormControl(''), // ... other controls }); } } Pass the Control to Your Custom Component: In your parent component's template, pass the specific FormControl instance to the custom input component. Use the Passed Control in Your Custom Component: In your custom input component's template, bind the passed FormControl to the input element using the Angular formControl directive. This approach removes the need for the get function, as you're passing the control directly. It also makes your custom component more reusable and easier to understand, as it explicitly defines what data it expects and works with. Remember, with this method, your custom component becomes tightly coupled with FormControl, making it specific to reactive forms. If you plan to use this component in template-driven forms, you might need to adjust your approach or create a separate version for that use case.
