Getting Started

This section explains how to create a simple DashboardLayout component and configure its available functionalities, using the Essential JS 2 quickstart seed repository.

Dependencies

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

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

Installation and configuration

  • Clone the Essential JS 2 quickstart application project from GitHub, and install necessary npm packages using the following command line scripts.
git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

The application is configured with all the EJ2 dependencies. For better understanding, remove common settings (src/styles/styles.css, system.config.js ) to get started with the DashboardLayout component.

[src/system.config.js]

System.config({
    paths: {
        //Syncfusion packages path mapping
        'npm:': './node_modules/',
        'syncfusion:': 'npm:@syncfusion/'
    },
    map: {
        app: 'app',
        //Syncfusion packages mapping
        typescript: "https://unpkg.com/typescript@2.2.2/lib/typescript.js",
        "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
        "@syncfusion/ej2-layouts": "syncfusion:ej2-layouts/dist/ej2-layouts.umd.min.js",
    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

System.import('app');

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/styles.css].

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

  • 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 component can defined through HTML attributes by using the predefined class .e-panel to the component child elements and data attributes for defining the sizeX, sizeY, row and column properties for each panel.

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

                </div>
            </div>
        </div>
</body>

</html>

Now, import the DashboardLayout component into your app.ts and append it to #dashboard_inline.

[src/app/app.ts]

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

// initialize dashboardlayout component
let dashboard: DashboardLayout  = new DashboardLayout ({
    columns: 5
});
// render initialized dashboardlayout
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.

Defining panels properties through script

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

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 dashboardlayout 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 dashboardlayout
dashboard.appendTo('#dashboard_default');

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