Getting started with Angular Dashboard Layout component

29 Jul 2021 / 5 minutes to read

This section explains how to create a simple DashboardLayout component and its basic usage.

Prerequisites

To get started with DashboardLayout component, ensure the compatible versions of Angular and Typescript.

  • Angular : 4+
  • Typescript : 2.6+

Setting up angular project

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

Install the CLI application globally to your machine by using following command.

Copied to clipboard
npm install -g @angular/cli

Create a new angular application

Copied to clipboard
ng new syncfusion-angular-app

Navigate to the created project folder by using following command.

Copied to clipboard
cd syncfusion-angular-app

Refer Syncfusion Angular Getting Started section to know more about setting up angular-cli project.

Adding Dependencies

The following list of dependencies are required to use the DashboardLayout component in your application.

Copied to clipboard
|-- @syncfusion/ej2-angular-layouts
|-- @syncfusion/ej2-angular-base
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-layouts
  • Install Syncfusion DashboardLayout package using below command.
Copied to clipboard
npm install @syncfusion/ej2-angular-layouts --save

The above package installs Dashboard Layout component dependencies which are required to render the component in an Angular environment.

Adding style sheet to the application

To render the DashboardLayout component, import the DashboardLayout and its dependent component’s styles as given below in [src/styles.css].

Copied to clipboard
@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-angular-layouts/styles/material.css";

Note: To refer the combined component styles, use Syncfusion CRG (Custom Resource Generator) in your application.

Add DashboardLayout to the application

You can render the DashboardLayout component in the following two ways.

  • Defined the panels property as the attribute in the HTML element directly.
  • Using the panels property through tag helper.

Setting the panels property using HTML attributes

You can render the DashboardLayout component by adding the panels property as the attribute to the HTML element directly. Add the HTML div element with panel definition for DashboardLayout into your app.template.html file.

[src/app/app.template.html]

<div class="control-section">
<ejs-dashboardlayout id='defaultLayout' [columns]="5" #defaultLayout [cellSpacing]='cellSpacing'>
    <div id="one" class="e-panel" data-row="0" data-col="0" data-sizeX="1" data-sizeY="1">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">0</div>
        </div>
    </div>
    <div id="two" class="e-panel" data-row="1" data-col="0" data-sizeX="1" data-sizeY="2">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">1</div>
        </div>
    </div>
    <div id="three" class="e-panel" data-row="0" data-col="1" data-sizeX="2" data-sizeY="2">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">2</div>
        </div>
    </div>
    <div id="four" class="e-panel" data-row="2" data-col="1" data-sizeX="1" data-sizeY="1">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">3</div>
        </div>
    </div>
    <div id="five" class="e-panel" data-row="2" data-col="2" data-sizeX="2" data-sizeY="1">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">4</div>
        </div>
    </div>
    <div id="six" class="e-panel" data-row="0" data-col="3" data-sizeX="1" data-sizeY="1">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">5</div>
        </div>
    </div>
    <div id="seven" class="e-panel" data-row="1" data-col="3" data-sizeX="1" data-sizeY="1">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">6</div>
        </div>
    </div>
    <div id="eight" class="e-panel" data-row="0" data-col="4" data-sizeX="1" data-sizeY="3">
        <span id="close" class="e-template-icon e-clear-icon"></span>
        <div class="e-panel-container">
            <div class="text-align">7</div>
        </div>
    </div>
</ejs-dashboardlayout>
</div>

Now, modify the templateUrl in app.component.ts file to render DashboardLayout component.

[src/app/app.component.ts]

Copied to clipboard
import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  styleUrls: ['default-style.css'],
  templateUrl: 'app.template.html'
})

export class AppComponent {
}
  • Import DashboardLayout module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-layouts.
Copied to clipboard
import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the DashboardLayoutModule for the Dashboard Layout component
import { DashboardLayoutModule } from '@syncfusion/ej2-angular-layouts';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of ej2-angular-layouts module into NgModule
  imports:      [ BrowserModule, DashboardLayoutModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Run the application

Now, use the npm start command to run the application in the browser.

Copied to clipboard
npm start

The following example shows a basic DashboardLayout by adding the panels property directly into the HTML element.

Setting the panels property through binding

You can render the DashboardLayout component by using the panels property through binding.

[src/app/app.template.html]

Copied to clipboard
<div class="control-section">
<ejs-dashboardlayout id='defaultLayout' #defaultLayout [cellSpacing]='cellSpacing' [panels]='panels' [columns]="5">
</ejs-dashboardlayout>
</div>

Now, modify the templateUrl in app.component.ts file to render DashboardLayout component.

[src/app/app.component.ts]

Copied to clipboard
import { Component,ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'app-root',
  styleUrls: ['app/default-style.css'],
  templateUrl: 'app/app.template.html',
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
  public cellSpacing: number[] = [10, 10];
  public panels: any = [{ "sizeX": 1, "sizeY": 1, "row": 0, "col": 0, content: '<div class="content">0</div>' },
{ "sizeX": 3, "sizeY": 2, "row": 0, "col": 1, content: '<div class="content">1</div>' },
{ "sizeX": 1, "sizeY": 3, "row": 0, "col": 4, content: '<div class="content">2</div>' },
{ "sizeX": 1, "sizeY": 1, "row": 1, "col": 0, content: '<div class="content">3</div>' },
{ "sizeX": 2, "sizeY": 1, "row": 2, "col": 0, content: '<div class="content">4</div>' },
{ "sizeX": 1, "sizeY": 1, "row": 2, "col": 2, content: '<div class="content">5</div>' },
{ "sizeX": 1, "sizeY": 1, "row": 2, "col": 3, content: '<div class="content">6</div>' }
  ]
}

The following example shows a basic DashboardLayout by using the panels property.
