Component vendor Telerik has released an updated version of Kendo UI, its HTML5 framework. This is the first non-beta release with support for ASP.NET MVC server wrappers, with components including Grid, ListView, calendar and date controls, tree view, menu, editor and more. Kendo UI supports the MVVM (Model View ViewModel) pattern popular with Microsoft developers.

 

Telerik seems to be treading a careful path, maintaining its strong links to the .NET developer community while also creating a framework that can be used on other platforms.

I spoke to Todd Anglin, VP of HTML5 tools. Why the support for ASP.NET MVC – is Telerik seeing this becoming more popular than Web Forms, the older ASP.NET approach to web applications?

“Something in the range of 70% of ASP.NET developers are on web forms. We do see a bit of a trend that as they start new projects, developers are adopting ASP.NET MVC and HTML5, which is where it makes sense to use Kendo UI,” he told me.

The main reason though is that Kendo UI is less suitable for Web Forms, where more of the client-side code is generated by the framework. “Web Forms are a very high level abstraction,” said Anglin. “With MVC developers are a little closer to the metal.”

That said, he is not ruling out a Web Form wrapper for Kendo UI long-term.

Anglin says Kendo UI’s use of JQuery is a distinctive feature.  “Over the last few years JQuery has clearly risen above the pack to be the most common core Javascript library and the one most developers are familiar with. Unlike most commercial libraries out there Kendo UI chooses the JQuery core as the starting point and builds on that, so developers that adopt Kendo UI have a smoother on-ramp.”

Kendo UI supports both mobile and desktop web applications, but with different controls. “We believe that developers should offer experiences that are tailored to each device class, which is why you have Kendo UI web for keyboard and mouse, and Kendo UI mobile with a mobile-specific interface. We share code behind that, like the data source, between web and mobile, but we don’t think the interface on a mobile device should be the same as you show on a desktop browser,” said Anglin.

What about the tools side? Although Anglin says “We want to be agnostic on tools”, there is particularly good support for Visual Studion. “Kendo UI integrates with anything that supports HTML and JavaScript well, which includes the latest version of Visual Studio. We are delivering full vsdoc support for Visual Studio so that developers in that environment get Intellisense for JavaScript. But if you’re on a Mac you can use other tools,” he told me.

More interesting is a forthcoming cloud IDE. “We’ve just revealed a new tool called Icenium which is a cloud-based development environment for creating apps in HTML and JavaScript. It’s an incredible environment for building apps with Kendo UI.”

How about HTML5 apps that target the Windows Runtime (Metro) in Windows 8 – will Kendo UI work there? Apparently not:

“It’s certainly something we’ve paid attention to. Telerik’s primary position for Windows 8 runtime and Windows 8 development is with the traditional .NET targeted tools. Our RAD tools later this year will focus on introducing XAML and HTML tools for Windows Runtime. The HTML tools that we introduce will have a shared engineering core with Kendo UI, but we’ll make a tool that is specifically targeted at that runtime.

“Kendo UI is really focused on the cross-platform, cross-browser experience. You write once, at a core code level, and then use all the runtimes out there for HTML and JavaScript. Whereas Windows Runtime is leveraging familiar technology in HTML and JavaScript, but when you write a Windows Runtime app you are writing Windows software. It’s very platform-specific.”
