Getting started in EJ2 TypeScript Dashboard layout control

7 May 202522 minutes to read

This section explains how to create a simple Dashboard Layout control and configure its available functionalities, using the Essential® JS 2 quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Dependencies

The following list of dependencies is required to use the Dashboard Layout control in your application.

|-- @syncfusion/ej2-layouts
    |-- @syncfusion/ej2-base

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion® JavaScript (Essential® JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion® JavaScript packages

Syncfusion® JavaScript (Essential® JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion® JavaScript (Essential® JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion® CSS styles

To render the Dashboard Layout control, import the Dashboard Layout and its dependent control’s styles as given below in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-layouts/styles/material.css";

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

Add Dashboard Layout to the application

You can render the Dashboard Layout control in the following two ways.

  • Adding dashboard element and defining panels property as attributes in the HTML elements directly.
  • Adding the dashboard element and defining the panels property through script.

Defining panels property through HTML attributes

The panels of the Dashboard layout control can defined through HTML attributes by using the predefined class .e-panel to the control child elements and data attributes for defining the sizeX, sizeY, row and col properties for each panel.

The following sample demonstrates defining of panels by adding child elements within the root element.

Now, import the Dashboard Layout control into your app.ts and append it to #dashboard_inline.

[src/app/app.ts]

import { DashboardLayout } from '@syncfusion/ej2-layouts';

// initialize Dashboard Layout control
let dashboard: DashboardLayout  = new DashboardLayout ({
    columns: 5
});
// render initialized Dashboard Layout
dashboard.appendTo('#dashboard_inline');

Run the application

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

npm run start

The below output can be achieved by following the steps mentioned above.

import { DashboardLayout } from '@syncfusion/ej2-layouts';

// initialize Dashboard Layout control
let dashboard: DashboardLayout = new DashboardLayout({
    cellSpacing: [10, 10],
    columns: 5
});
// render initialized Dashboard Layout
dashboard.appendTo('#dashboard_inline');

Defining panels properties through script

The panels can be defined simply during control initialization at the script section using the panels property of the control.

The following sample demonstrates defining panels property through script section. Here, the panels settings is defined using panels property with same settings as in HTML definition in the previous section.

[src/app/app.ts]

import { DashboardLayout } from '@syncfusion/ej2-layouts';

// initialize Dashboard Layout control
let dashboard: DashboardLayout  = new DashboardLayout ({
    cellSpacing: [10, 10],
    columns: 5,
    panels: [{ "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>' }
    ]
});
// render initialized Dashboard Layout
dashboard.appendTo('#dashboard_default');

The following example shows a basic Dashboard Layout by defining the panels property through script.

import { DashboardLayout } from '@syncfusion/ej2-layouts';

// initialize Dashboard Layout component
let dashboard: DashboardLayout = new DashboardLayout({
    cellSpacing: [10, 10],
    columns: 5,
    panels: [{ "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>' }
    ]
});
// render initialized Dashboard Layout
dashboard.appendTo('#dashboard_default');
