.net core and telerik ninja

Today we have five powerful platforms/environments for cross-platform software:

Windows  Apple  Android  iOS  Linux
Windows, Apple, Android, iOS and Linux!

Telerik UI for ASP.NET Core runs on those operating systems smoothly due to its cross-platform web-based nature. With this toolkit, you can find everything you need to build an excellent UI, including an optional abstraction layer data source to perform powerful data operations.

In addition, Telerik UI for ASP.NET Core is one of the most complete and user-friendly component libraries on the market. The components are lightweight and designed for performance, offering high customization and accessibility. Plus, with built-in themes, you can be sure that your application will look amazing.

Offering software for mainstream platforms like Windows, macOS, iOS and Android via cloud computing or on premises generates a differential while exploring the vast market in a world post-pandemic. Moreover, each user can access the same data source with their device, BYOD (bring your own device) or not, reducing the knowledge learning curve with reliability.

Some of the most popular Telerik UI for ASP.NET Core components include the Grid, Charts, Scheduler and ListView. With these controls, you can build a robust, responsive web application that your users will love. One of the most significant advantages is the ability to add to your current application control by control as you need.

Kendo UI on the Client-Side

Telerik UI for ASP.NET Core uses the Kendo UI framework on the client-side (Telerik UI Tag Helpers and Telerik UI HTML Helpers) and server-side wrappers. It is built on top of the ASP.NET Core platform and uses the jQuery JavaScript library.

Adding a button in Kendo UI is done like this:

.Content("Primary Button")

    SupportedCultures = supportedCultures,
    SupportedUICultures = supportedCultures

The client-side needed a few lines of code too.
