Telerik UI for ASP.NET MVC R1 2021 SP1 (v2021.1.224) Retail
Cut development time, while delivering rich, powerful, modern websites and apps. Telerik® UI for ASP.NET MVC offers 70+ jQuery-based components ranging from must-have HTML helpers for every app like Grids, Dropdowns and Menus to advanced line-of-business controls such as Charts, Gantt, Diagram, Scheduler, PivotGrid and Maps.
Despite the variety of built-in functionality the product offers, we continue to release new functionality based on customer feedback three times a year. Feel free to suggest product ideas for the community to vote on in Telerik feedback portal—the more votes your suggestion receives, the higher priority it becomes to introduce into our roadmap.
Telerik ASP.NET MVC components are comprised of Telerik award-winning Kendo UI HTML5/JS widgets and their server-side wrappers for ASP.NET MVC. The wrappers generate the jаvascript and HTML required by the Kendo UI widgets enabling you to use C# to configure them.
Telerik UI for ASP.NET MVC ships the same built-in functionality as Kendo UI, but offers MVC-specific features on top, including:
Server-side data binding and in some cases server-side rendering
Support for unobtrusive validation based on Data Annotation attributes
Visual Studio intellisense for the server-side configuration syntax
Visual Studio Extensions for automatic creation of new applications
Built-in editor templates and more
Mobile Support and Responsiveness
Telerik® UI for ASP.NET MVC saves you time and effort when implementing responsive design practices, because the controls take care of them out-of-the-box or with the change of a single property:
All components render larger clickable areas on small screens and scale proportionately to the container in which they are placed
All components integrate well with grid-layout frameworks, such as Bootstrap and Zurb Foundation
The complex and popular components, such as Grid and Scheduler, serve different rendering on small screens to provide optimal user experience
Simple Server-Side Data Binding and CRUD
If you are familiar with server-side programming, it can be hard to work with data in HTML5. Telerik UI for ASP.NET MVC makes data binding simple. Use your existing server-side data access technologies to quickly bind data to the UI widgets via our DataSource component. With it, you can define endpoints for read and data editing operations, as well as mappings for requests between .NET and jаvascript.
Conversational UI - Modern UI for Chatbots
The Conversational UI control (aka RadChat) is a new control intended to be used with various chat bot services. Highlights of the features include:
Built-in hero cards
Built-in suggested actions
Built-in simple message and typing indicator
Custom card/attachment templates
Easy connectivity to chat bot services (Azure/Microsoft Bot Framework, Wit.ai, Amazon Lex)
Document Processing
Take advantage of the RadSpreadProcessing, RadSpreadStreamProcessing, RadWordsProcessing, RadPdfProcessing and libraries, which enable the processing of the most common text, spreadsheet, and PDF file formats without having Microsoft Office or other third-party libraries installed. Now application users can create, load and modify documents in a variety of formats including:
DOCX
RTF
TXT
HTML
XLSX
CSV
Tab-delimited
Enable your application to seamlessly export and import documents or convert them from one format to another. In addition, the zip library allows you to create and modify archives with variety of compression mechanisms supported, so you can transfer data faster and secure.
Use Bower and NuGet
Popular package management and task automation solutions such as NuGet, Bower and Gulp are made first class citizens in ASP.NET MVC. That means every web developer can use Bower for client packages, NuGet for server packages and Grunt/Gulp for compilation, minification, etc., when building web apps.
UI for ASP.NET MVC takes advantage of these tools by providing a Bower feed for its client scripts, and a NuGet feed, hosted on our NuGet server, for its server wrappers implementation (see this help topic for details). Furthermore, you can build a custom script from the source using Grunt by following these steps.
Built-In, Yet Customizable Themes
Kendo UI widgets can easily be themed and styled via CSS. The framework includes 11 out-of-the-box themes created by Telerik's professional designers, so you can create sleek modern apps without a designer on-hand.
The themes can also help you style normal HTML elements, like buttons and inputs, so all elements on your page look consistent. Simply use the basic CSS classes included in Kendo UI and apply a professional CSS theme to your entire page.
Transforming the ready-made themes to perfectly match your site is also easy when using the ThemeBuilder tool. With the point-and-click configuration wizard, your new themes are ready in a matter of seconds.
Seamless UX Across Browsers
Although based on HTML5, UI for ASP.NET Core makes sure your sites and apps look and work flawlessly across all browsers, while maximizing performance. It uses HTML5 features when available, adds support for them when necessary and provides fine-tuned graceful degradation for others.
The widgets support all major browsers, including: Edge 20+, Internet Explorer 8+, Firefox, Chrome 21+, Safari 6.2+ (OSX) and Opera 15+.
