Getting started with Angular DatePicker component

The following section explains the steps required to create a simple DatePicker component and also it demonstrates the basic usage of the DatePicker.

Dependencies

Install the below required dependency package in order to use the DatePicker component in your application.

|-- @syncfusion/ej2-angular-calendars
    |-- @syncfusion/ej2-angular-base
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-calendars
        |-- @syncfusion/ej2-lists
        |-- @syncfusion/ej2-inputs
          |-- @syncfusion/ej2-splitbuttons
        |-- @syncfusion/ej2-popups
            |-- @syncfusion/ej2-buttons

Setup Angular environment

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine.

npm install -g @angular/cli

Create a new application

ng new syncfusion-angular-datepicker

By default, it install the CSS style base application. To setup with SCSS, pass —style=scss argument on create project.

Example code snippet.

ng new syncfusion-angular-datepicker --style=scss

Navigate to the created project folder.

cd syncfusion-angular-datepicker

Adding DatePicker package

All the available Essential JS 2 packages are published in npmjs.com registry.

To install DatePicker component, use the following command.

npm install @syncfusion/ej2-angular-calendars --save
(or)
npm I @syncfusion/ej2-angular-calendars --save

The —save will instruct NPM to include the DatePicker package inside of the dependencies section of the package.json.

Registering DatePicker module

Import DatePicker module into Angular application(src/app/app.module.ts) from the package @syncfusion/ej2-angular-calendars.

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the DatePickerModule for the DatePicker component
import { DatePickerModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of DatePickerModule into NgModule
  imports:      [ BrowserModule, DatePickerModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Adding CSS reference

The following CSS files are available in ../node_modules/@syncfusion package folder. This can be referenced in [src/styles.css] using following code.

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-calendars/styles/material.css';
@import '../node_modules/@syncfusion/ej2-angular-calendars/styles/material.css';

If you want to refer the combined component styles, please make use of our CRG (Custom Resource Generator) in your application.

Adding DatePicker component

Modify the template in [src/app/app.component.ts] file to render the DatePicker component. by using <ejs-datepicker> selector.

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `<!-- To Render DatePicker -->
             <ejs-datepicker></ejs-datepicker>`
})
export class AppComponent  { }

Running the application

After completing the configuration required to render a basic DatePicker, run the following command to display the output in your default browser.

ng serve

The following example illustrates the output in your browser

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<ejs-datepicker></ejs-datepicker>`
})
export class AppComponent {
    constructor() {
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { DatePickerModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent } from './app.component';


/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        DatePickerModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Setting the selected date

To set the selected date, use the value property.

The below example demonstrates the DatePicker with current date as selected one.

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<ejs-datepicker [value]='dateValue' placeholder='Enter date'></ejs-datepicker>`
})
export class AppComponent {
    public dateValue: Date = new Date();
    constructor() {
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { DatePickerModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent } from './app.component';


/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        DatePickerModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Setting the date range to restrict selection

To restrict the selection of date within a specified range, use the min and max properties. To know more about range restriction in DatePicker, please refer this page.

The below example demonstrates the DatePicker to select a date within a range from 7 to 27.

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `
        <ejs-datepicker id="datepicker" [min]='minDate' [max]='maxDate'></ejs-datepicker>
        `
})
export class AppComponent {
    public month: number = new Date().getMonth();
    public fullYear: number = new Date().getFullYear();
    public minDate: Date = new Date(this.fullYear, this.month , 7);
    public maxDate: Date = new Date(this.fullYear, this.month, 27);
    constructor() {
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { DatePickerModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent } from './app.component';


/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        DatePickerModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
