Bind Saved Date in Edit Form using Angular 17: A Step-by-Step Guide

Posted on

Hey there, fellow Angular developers! Are you tired of struggling to bind saved dates in edit forms using Angular 17? Well, you’re in luck because today, we’re going to dive into the world of Angular forms and explore how to bind saved dates like a pro!

What’s the Big Deal About Binding Saved Dates?

When working with forms in Angular, one of the most common requirements is to display saved data in edit mode. This can be particularly challenging when dealing with dates, as the default Angular date picker doesn’t quite play nice with saved dates. But fear not, dear reader, because we’re about to tackle this issue head-on and come out victorious!

The Problem: Default Angular Date Picker Behavior

By default, the Angular date picker sets the date to the current date when the form is loaded, regardless of the saved date. This can be frustrating, especially when you need to display the saved date in edit mode. But don’t worry, we can override this behavior with a little bit of creativity and some clever coding!

Solution: Bind Saved Date using Angular 17

To bind the saved date in an edit form using Angular 17, we’ll create a custom date picker component that takes into account the saved date. We’ll use the Angular Material library to create a beautiful and functional date picker.

Step 1: Create a Custom Date Picker Component

<import>
  { 
    MatDatepickerModule, 
    MatInputModule, 
    MatNativeDateModule 
  } 
  from '@angular/material';
  
  @NgModule({
    imports: [ 
      MatDatepickerModule, 
      MatInputModule, 
      MatNativeDateModule 
    ]
  })
  export class AppModule {}

In the above code, we’re importing the necessary Angular Material modules to create our custom date picker component.

Step 2: Create a Custom Date Picker Component HTML

<mat-form-field>
  <input 
    matInput 
    [matDatepicker]="picker" 
    [value]="savedDate | date: 'MM/dd/yyyy'" 
    (dateInput)="handleDateInput($event)" 
    (dateChange)="handleDateChange($event)">
  <mat-datepicker #picker></mat-datepicker>
  <mat-datepicker-toggle matSuffix><mat-icon mat-datepicker-toggle-icon>calendar</mat-icon></mat-datepicker-toggle>
</mat-form-field>

In the above HTML, we’re creating a custom date picker component using the Angular Material library. We’re also using pipes to format the saved date in the desired format (MM/dd/yyyy).

Step 3: Create a Custom Date Picker Component TS

import { Component, OnInit } from '@angular/core';
import { FormControl } from '@angular/forms';
import { MatDatepicker } from '@angular/material/datepicker';

@Component({
  selector: 'app-date-picker',
  templateUrl: './date-picker.component.html',
  styleUrls: ['./date-picker.component.css']
})
export class DatePickerComponent implements OnInit {
  savedDate = new Date('2022-01-01T00:00:00.000Z');
  dateFormControl = new FormControl(this.savedDate);

  constructor() { }

  ngOnInit(): void {
  }

  handleDateInput(event: any): void {
    console.log('handleDateInput:', event);
  }

  handleDateChange(event: any): void {
    console.log('handleDateChange:', event);
  }
}

In the above TS file, we’re creating a custom date picker component that takes into account the saved date. We’re also using the FormControl to bind the saved date to the date picker.

Binding the Saved Date in Edit Form

Now that we have our custom date picker component, let’s see how to bind the saved date in an edit form using Angular 17.

Step 1: Create an Edit Form Component

<form [formGroup]="editForm">
  <app-date-picker 
    formControlName="date" 
    [savedDate]="savedDate">
  </app-date-picker>
</form>

In the above HTML, we’re creating an edit form that includes our custom date picker component. We’re also passing the saved date as an input to the custom date picker component.

Step 2: Create an Edit Form Component TS

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

@Component({
  selector: 'app-edit-form',
  templateUrl: './edit-form.component.html',
  styleUrls: ['./edit-form.component.css']
})
export class EditFormComponent implements OnInit {
  savedDate = new Date('2022-01-01T00:00:00.000Z');
  editForm: FormGroup;

  constructor(private fb: FormBuilder) { }

  ngOnInit(): void {
    this.editForm = this.fb.group({
      date: [this.savedDate, Validators.required]
    });
  }
}

In the above TS file, we’re creating an edit form component that includes our custom date picker component. We’re also creating a form group and passing the saved date as an initial value to the date form control.

Conclusion

And that’s it, folks! We’ve successfully bound the saved date in an edit form using Angular 17. By creating a custom date picker component and using the Angular Material library, we’ve overridden the default Angular date picker behavior and achieved our desired result.

Remember, when working with forms in Angular, it’s essential to think creatively and outside the box. With a little bit of coding magic, we can create complex and functional forms that meet our requirements.
