Tree List - Overview
DevExtreme ASP.NET Core Tree List is a jQuery-based client-side component with features like data shaping, editing, validation, searching, filtering, and layout customization. It includes strongly-typed HTML helpers for client-side validation through Data Annotations. You can configure it with Razor C# syntax for use in both MVC views and Razor Pages.
