Getting Started with ASP.NET Core Sidebar Control

6 Dec 202424 minutes to read

This section briefly explains about how to include ASP.NET Core Sidebar control in your ASP.NET Core application using Visual Studio.

Prerequisites

System requirements for ASP.NET Core controls

Create ASP.NET Core web application with Razor pages

Install ASP.NET Core package in the application

To add ASP.NET Core controls in the application, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.EJ2.AspNet.Core and then install it. Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.EJ2.AspNet.Core -Version 28.1.33

NOTE

Syncfusion® ASP.NET Core controls are available in nuget.org. Refer to NuGet packages topic to learn more about installing NuGet packages in various OS environments. The Syncfusion.EJ2.AspNet.Core NuGet package has dependencies, Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating Syncfusion® license key.

Add Syncfusion® ASP.NET Core Tag Helper

Open ~/Pages/_ViewImports.cshtml file and import the Syncfusion.EJ2 TagHelper.

@addTagHelper *, Syncfusion.EJ2

Add stylesheet and script resources

Here, the theme and script is referred using CDN inside the <head> of ~/Pages/Shared/_Layout.cshtml file as follows,

<head>
    ...
    <!-- Syncfusion ASP.NET Core controls styles -->
    <link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/28.1.33/fluent.css" />
    <!-- Syncfusion ASP.NET Core controls scripts -->
    <script src="https://cdn.syncfusion.com/ej2/28.1.33/dist/ej2.min.js"></script>
</head>

NOTE

Checkout the Themes topic to learn different ways (CDN, NPM package, and CRG) to refer styles in ASP.NET Core application, and to have the expected appearance for Syncfusion® ASP.NET Core controls.

NOTE

Checkout the Adding Script Reference topic to learn different approaches for adding script references in your ASP.NET Core application.

Register Syncfusion® Script Manager

Also, register the script manager <ejs-script> at the end of <body> in the ASP.NET Core application as follows.

<body>
    ...
    <!-- Syncfusion ASP.NET Core Script Manager -->
    <ejs-scripts></ejs-scripts>
</body>

Add ASP.NET Core Sidebar control

Now, add the Syncfusion® ASP.NET Core Sidebar tag helper in ~/Pages/Index.cshtml page.

<!-- sidebar element declaration -->
<ejs-sidebar id="default-sidebar" closeOnDocumentClick="false">
	<e-content-template>
		<div class="title-header">
			<div style="display:inline-block"> Sidebar </div>
		</div>
	</e-content-template>
</ejs-sidebar>
<!-- end of sidebar element -->
<!--  Main Content declaration -->
<div>
	<div class="title default">Main content</div>
	<div class="sub-title">
		Place your primary content here.
	</div>
</div>

<style>
    /* sample level styles */
    .center-align {
        text-align: center;
        padding: 20px;
    }

    .title {
        text-align: center;
        font-size: 20px;
        padding: 15px;
    }

    .sub-title {
        text-align: center;
        font-size: 16px;
        padding: 10px;
    }

    body {
        padding-top: 0px;
        padding-bottom: 0px;
    }

    .title-header {
        text-align: center;
        font-size: 18px;
        padding: 15px;
    }

    .title.default {
        padding: 25px 15px 15px;
    }
    /* sidebar element styles */
    #default-sidebar {
        background-color: rgb(25, 118, 210);
        color: #ffffff;
    }
</style>

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the app. Then, the Syncfusion® ASP.NET Core Sidebar control will be rendered in the default web browser.

ASP.NET Core Sidebar Control

Enable backdrop

Enabling the showBackdrop in the Sidebar component will prevent the main content from user interactions. Here, the DOM elements will not get changed. It only closes the main content by covering with a black backdrop overlay and focuses the Sidebar in the screen. Sidebar can be rendered with specific width by setting width property.

NOTE

To achieve a proper backdrop, we suggest that you create a wrapper parent container for the div block in which you intend to enable the backdrop. Set the class name of this parent container as the target for the Sidebar. Alternatively, you can place an empty div container after the target container.

The following example shows a Sidebar component with enabled backdrop.

<!-- sidebar element declaration -->
<ejs-sidebar id="default-sidebar" showBackdrop="true" type="Push" width="280px">
    <e-content-template>
        <div class="title"> Sidebar content</div>
        <div class="sub-title">
            Click the button to close the Sidebar.
        </div>
        <div class="center-align">
            <!-- button element declaration -->
            <ejs-button id="close" content="Close Sidebar"></ejs-button>
        </div>
    </e-content-template>
</ejs-sidebar>
<!-- end of sidebar element -->
<!-- main content declaration -->
<div>
    <div class="title">Main content</div>
    <div class="sub-title"> Click the button to open/close the Sidebar.</div>
    <div style="padding:20px" class="center-align">
        <!-- button element declaration -->
        <ejs-button id="toggle" content="Toggle Sidebar" cssClass="e-info"></ejs-button>
    </div>
</div>

<script type="text/javascript">
    document.addEventListener('DOMContentLoaded', function () {
        //create instances for sidebar element
        var defaultSidebar = document.getElementById("default-sidebar").ej2_instances[0];
        // Toggle Button to close and open the sidebar
        document.getElementById('toggle').onclick = function () {
            defaultSidebar.toggle();
        }
        // Close the sidebar
        document.getElementById('close').onclick = function () {
            defaultSidebar.hide();
        }
    });
</script>

<style>
    /* sample level styles */
    .center-align {
        text-align: center;
        padding: 20px;
    }

    .title {
        text-align: center;
        font-size: 20px;
        padding: 15px;
    }

    .sub-title {
        text-align: center;
        font-size: 16px;
        padding: 10px;
    }
    /* Button styles */
    #close, #close:hover, #close:active, #close:focus { /* csslint allow: adjoining-classes*/
        background: #fafafa;
        color: black
    }
    /* sidebar element styles */
    #default-sidebar {
        background-color: rgb(25, 118, 210);
        color: #ffffff;
    }
</style>

Enable Backdrop in ASP.NET Core Sidebar

Position

Positioning the Sidebar to the right or left of the main content can be achieved by using the positionproperty. If the position is not set, the Sidebar will expand from the left to the body element. enablePersistence will persist the component’s state between page reloads. change event will be triggered when the state(expand/collapse) of the component is changed.

In the following sample, the sidebar is rendered with position property.

<!-- sidebar element declaration -->
<ejs-sidebar id="default-sidebar" enablePersistence="true" type="Push" width="280px" target=".maincontent">
    <e-content-template>
        <div class="title"> Sidebar content</div>
        <div class="sub-title">
            Click the button to close the Sidebar.
        </div>
        <div class="center-align">
            <!-- Button element declaration -->
            <ejs-button id="close" content="Close Sidebar"></ejs-button>
        </div>
    </e-content-template>

Changing ASP.NET Core Sidebar Position

Animate

Animation transitions can be set while expanding or collapsing the Sidebar using the animate property. By default , animate property is set to true. enableRTL will display the sidebar in the right-to-left direction.

<!-- sidebar element declaration -->

Sidebar Sample

Close on document click

Sidebar can be closed on document click by setting closeOnDocumentClick to true. If this property is not set, the Sidebar will not close on document click since its default value is false. Sidebar can be kept opened during rendering using isOpen property.

<!-- sidebar element declaration -->
<ejs-sidebar id="default-sidebar" closeOnDocumentClick="true" isOpen="true" type="Push" width="280px">
    <e-content-template>
        <div class="title"> Sidebar content</div>

</ejs-sidebar>
<!-- end of sidebar element -->
