Getting started with ASP.NET Core Sidebar control

This section briefly explains about how to include a simple Sidebar in your ASP.NET Core application. You can refer ASP.NET Core Getting Started documentation page for introduction part of the system requirements and configure the common specifications.

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your ASP.NET Core application to use our components.

Adding component to the Application

  • Now open your view page to render Sidebar components.
 <!-- sidebar element declaration -->
<ejs-sidebar id="default-sidebar">
     <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 class="title default">
    Main content
</div>
<div class="sub-title">
     Place your primary content here.
</div>

Run the application

After successful compilation of your application, simply press F5 to run the application.

The following example shows a basic Sidebar component.

Sidebar Sample

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.

The following example shows a Sidebar component with enabled backdrop.

<!-- sidebar element declaration -->
<ejs-sidebar id="default-sidebar" showBackdrop="true" type="Push" width="280px">

Sidebar Sample

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.
