How can I validate forms in Angular Material dialogs?

You can use Angular's reactive forms along with Angular Material's dialog component to validate forms. Would you like a code example?

Yes, please provide a code example for a simple form.

Sure! Here's a basic example:

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

@Component({
  selector: 'app-dialog',
  templateUrl: './dialog.component.html',
})
export class DialogComponent {
  form: FormGroup;

  constructor(private fb: FormBuilder) {
    this.form = this.fb.group({
      name: ['', Validators.required],
      email: ['', [Validators.required, Validators.email]],
    });
  }

  onSubmit() {
    if (this.form.valid) {
      // Handle valid form submission
    }
  }
}

This sets up a form with validation for name and email.

How do I display error messages for invalid fields?

You can use Angular Material's form field error messages. Here's how you can do it:

<mat-form-field>
  <input matInput [formControl]='form.get("name")' placeholder='Name'>
  <mat-error *ngIf="form.get('name').hasError('required')">Name is required.</mat-error>
</mat-form-field>
