Overview

The ASP.NET Core Checkbox is a custom checkbox-type HTML5 input control for selecting one or more options from a list of predefined choices. It supports an indeterminate state, different sizes, custom labels and positions, and UI customization.

Checkbox states

A single checkbox consists of toggle states for performing check and uncheck actions. To prevent the toggling of a checkbox value, you can use the disable option.

Tri-state or indeterminate checkbox

The ASP.NET Core Checkbox control also features a built-in indeterminate state for option selections.

Checkbox size

You can use different checkbox sizes, default and small, as required in your application.

Great tool, saves alot of time, and great support

Syncfusion really makes it simple to implement features that would take a ton of time and effort to create. When you're building your site, the UI can take a ton of time away from building the core app. With Syncfusion's tools it reduces that effort significantly so you can get back to building the core elements.
