Getting started

This section explains the steps to create a simple Dialog component and configure its available functionalities in Angular.

Getting Started with Angular CLI

The following section explains the steps required to create a simple angular-cli application and how to configure Dialog component.

Prerequisites

To get started with Syncfusion Angular UI Components, make sure that you have compatible versions of Angular and TypeScript.

Angular : 4+
TypeScript : 2.6+

Setting up an Angular project

Angular provides an easiest way to setup project using Angular CLI Angular CLI tool.

Install the CLI application globally in your machine.

  npm install -g @angular/cli

Create a new application

  ng new syncfusion-angular-app

Once you have executed the above command you may ask for following options,

Would you like to add Angular routing?
Which stylesheet format would you like to use?

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-app --style=SCSS

Use below command to Navigate into the created project folder.

  cd syncfusion-angular-app

Install Syncfusion Popups package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the angular Syncfusion package from npm link.

Add Syncfusion Angular popups package in your application by using following Command,

npm install @syncfusion/ej2-angular-popups --save
(or)
npm i @syncfusion/ej2-angular-popups --save

Adding Dialog module

Once you have successfully installed the popups package, the component modules are ready to configure in your application from the installed location. Syncfusion Angular package provides two different types of ngModules.

Refer to Ng-Module to learn about ngModules.

Refer to the following snippet to import the DialogModule in app.module.ts from the @syncfusion/ej2-angular-popups.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
// Imported syncfusion DialogModule from popups package
import { DialogModule } from '@syncfusion/ej2-angular-popups';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    // Registering EJ2 Dialog Module
    DialogModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Adding Dialog component

Add the Dialog component snippet in app.component.ts as follows.

import { Component, ViewChild, OnInit, ElementRef  } from '@angular/core';
import { DialogComponent } from '@syncfusion/ej2-angular-popups';
import { EmitType } from '@syncfusion/ej2-base';

@Component({
  selector: 'app-root',
  template: `
  <button class="e-control e-btn" style="position: absolute;" id="targetButton" (click)="onOpenDialog($event)">Open Dialog</button>
  <div #container class='root-container'></div>
  <ejs-dialog id='dialog' #ejDialog content='This is a Dialog with content' [target]='targetElement' width='250px'>
  </ejs-dialog>`
})
export class AppComponent implements OnInit {
  @ViewChild('ejDialog') ejDialog: DialogComponent;
  // Create element reference for dialog target element.
  @ViewChild('container', { read: ElementRef }) container: ElementRef;
  // The Dialog shows within the target element.
  public targetElement: HTMLElement;

  // To get all element of the dialog component after component get initialized.
  ngOnInit() {
    this.initilaizeTarget();
  }

  // Initialize the Dialog component target element.
  public initilaizeTarget: EmitType<object> = () => {
    this.targetElement = this.container.nativeElement.parentElement;
  }
  // Sample level code to handle the button click action
  public onOpenDialog = function(event: any): void {
      // Call the show method to open the Dialog
      this.ejDialog.show();
  };
}

Add following styles in corresponding css file. The below mentioned styles are used in styles.css file,

html,
body,
#dialog-container {
    display: block;
    height: 100%;
    margin: 0;
    overflow: hidden;
    width: 100%;
}

Note: Please do the necessary change in index.html file. In this demo we used id selector in <app-root id='dialog-container'></app-root>

Adding CSS reference

Add Dialog component styles as given in the angular-cli.json file within the apps -> styles section.

Note: If you are using Angular 6 project, add the changes in angular.json file.

{
"apps": [
  {
    "styles": [
      "src/styles.css",
      "node_modules/@syncfusion/ej2-base/styles/material.css",
      "node_modules/@syncfusion/ej2-icons/styles/material.css",
      "node_modules/@syncfusion/ej2-buttons/styles/material.css",
      "node_modules/@syncfusion/ej2-angular-popups/styles/material.css"
    ],
  }
  ]
}

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific components. This web tool is useful to combine the required component scripts and styles in a single file.

Running the application

Run the ng serve command in command window, it will serve your application and you can open the browser window. Output will appear as follows.

A modal shows an overlay behind the Dialog. So, the user should interact the Dialog compulsory before interacting with the remaining content in an application.

While the user clicks the overlay, the action can be handled through the overlayClick event. In the below sample the Dialog close action is performed while clicking on the overlay.

When the modal Dialog is opened, the Dialog’s target scrolling will be disabled. The scrolling will be enabled again once close the Dialog.

The Dialog provides built-in support to render the buttons on the footer (for ex: ‘OK’ or ‘Cancel’ buttons). Each Dialog button allows the user to perform any action while clicking on it.

The primary button will be focused automatically when open the Dialog and add the click event to handle the actions

When the Dialog initialize with more than one primary buttons, the first primary button gets focus on open the Dialog.

The below sample render with button and its click event.

Draggable

The Dialog supports to drag within its target container by grabbing the Dialog header, which allows the user to reposition the Dialog dynamically.

The Dialog can be draggable only when the Dialog header is enabled. From 16.2.x version, enabled draggable support for modal Dialog also.

    position: absolute;
    top: 45%;

}

Positioning

The Dialog can be positioned using the position property by providing the X and Y co-ordinates. It can be positioned inside the target of the container or <body> of the element based on the given X and Y values.

for X is: left, center, right (or) any offset value
for Y is: top, center, bottom (or) any offset value

The below example demonstrates the different Dialog positions.
