Getting started in EJ2 TypeScript Dashboard layout control

24 Jul 202623 minutes to read

This section explains the steps to create a simple Dashboard Layout and demonstrates the basic usage of the Dashboard Layout component using the Essential® JS 2 quickstart seed repository. This seed repository is pre-configured with the Essential® JS 2 package.

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.

Prerequisites

Ensure the following tools are installed on your machine:

Set up the development environment

Clone the Syncfusion® TypeScript (Essential® JS 2) quickstart project from GitHub in the command prompt:

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

Navigate to the project folder in the command prompt:

cd ej2-quickstart

Install Syncfusion® Dashboard Layout package

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

Use the following command to install the @syncfusion/ej2-layouts package:

npm install @syncfusion/ej2-layouts --save

Then, install the remaining dependent npm packages using the following command:

npm install

For more information about individual package and alternative installation methods, see the installation guide.

Import Syncfusion® Dashboard Layout CSS styles

Syncfusion® JavaScript controls provide built-in themes, which are available from the npm theme packages. Additionally, themes can be loaded via CDN or customized using the Theme Studio. For more information, refer to the themes documentation.

The quickstart application is preconfigured to use the Fluent2 theme. To install the Fluent2 theme package, use the following command:

npm install @syncfusion/ej2-fluent2-theme --save

The required styles are imported in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-fluent2-theme/styles/dashboard-layout/index.css";

Learn more about built-in themes and individual control CSS references.

Add Syncfusion® Dashboard Layout control 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.

Open the application in Visual Studio Code and add the Syncfusion® TypeScript UI controls.

In this article, the Dashboard Layout control is used as an example. Add the following Dashboard Layout element to the ~/src/index.html file.

        <div id="dashboard_inline">
            <div id="one" class="e-panel" data-row="0" data-col="0" data-sizeX="1" data-sizeY="1">

            <div id="six" class="e-panel" data-row="2" data-col="2" data-sizeX="1" data-sizeY="1">

            </div>
            <div id="seven" class="e-panel" data-row="2" data-col="3" data-sizeX="1" data-sizeY="1">
                <div class="e-panel-container">
                    <div class="content">6</div>
                </div>
            </div>
        </div>
        <style>
            #container {
                margin: 0 auto;
                width: 500px;
            }

            #dashboard_inline .e-panel .e-panel-container .content {
                vertical-align: middle;
                font-weight: 600;
                font-size: 20px;
                text-align: center;
                line-height: 90px;
            }

            #dashboard_inline .e-panel {
                transition: none !important;
            }
        </style>
</body>

</html>

Now, to render the Dashboard Layout control, add the following TypeScript code to the ~/src/app/app.ts file.

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, run the application in the browser using the following command.

npm 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');
