Operating System, Visual Studio, and Browser Support

The Telerik UI for ASP.NET MVC components are designed to support all major operating systems and the most popular Visual Studio versions. The components also support all major web browsers and deliver cross-browser compatibility, standards compliance, and touch-device support.

Operating System Support

Telerik UI for ASP.NET MVC supports the following operating systems:

Windows XP or later
Windows Server Server 2003 or later
OS X 10.5 or later
Android 2.3 or later
iOS 6.0 or later
Windows Phone 8.0 or later
  • Telerik UI supports hybrid mouse and touch-screen devices.
  • To allow any browser to run scripts, enable JavaScript in the browser.

Visual Studio Support

Telerik UI for ASP.NET MVC supports Visual Studio 2013 and later. The supported development environments also include:

As of the R3 2022 release, MVC 3 and MVC 4 are no longer supported by Telerik UI for ASP.NET MVC.

Following Microsoft's announcement about Internet Explorer (IE) being officially retired and out of support, the Telerik UI for ASP.NET MVC and Kendo UI products will no longer support IE as of their R1 2023 release. The components will not be tested against and no fixes will be implemented for any IE version. If your project requires you to use the UI components in IE, it is recommended that you download a product version that is prior to Telerik UI for ASP.NET MVC R1 2023.

Web Browsers Support

The Telerik UI for ASP.NET MVC helpers and framework components deliver support for all popular browsers. However, depending on the specifics of your project, the components you use, and the versions of the helpers, their browser support may vary. For example, advanced component features usually require more recent browser versions.

To allow the browsers to run the scripts required by the Telerik components, enable JavaScript on all of them.

Regular Support

Most Telerik UI for ASP.NET MVC helpers have no specific limitations for the browser versions they support.

Edge 20 or later (officially supported versions by Microsoft only)
Internet Explorer* 9 or later Some features may not be available due to browser limitations
Chrome Current and previous
Firefox Current and ESR releases (What is ESR?)
Opera 15 or later
OS X Safari 6.2.6 or later

Support for Data Visualizing Helpers

The Telerik UI for ASP.NET MVC helpers which render data visualization, such as the Charts, Gauges, Barcodes, Diagrams, and Maps, may require more recent browser versions according to the following table.

  • Fully supported browsers

    Edge 20 or later (officially supported versions by Microsoft only)
    Internet Explorer 9 or later
    Chrome Current and previous
    Firefox Current and ESR releases (What is ESR?)
    Opera 15 or later
    OS X Safari 6.2.6 or later
    iOS Safari iOS 8 or later
    Chrome for Mobile 21 or later
  • Browsers with limited support

    Internet Explorer 10 Dashed lines in canvas are not supported, which affects the image export as well
    Android 2.x, therefore, uses non-interactive canvas output
    Android 2.3 The Canvas rendering mode is only supported

Support for PDF Export

The Telerik PDF generator is tested and supported in the following desktop browsers:

  • Internet Explorer 9 and later.
  • Latest Chrome, Firefox, Safari, and Blink-based Opera versions.

Internet Explorer 9 and Safari do not support the PDF-related option for saving files. To achieve this, you need to implement a server proxy.

Officially, PDF export is not supported on mobile because of browser limitations and CORS-related security restrictions in hybrid applications. For example, it is not possible to load locally stored font files in hybrid applications. Even though exporting in PDF might work on some mobile devices in specific scenarios, PDF export is not supported in mobile browsers and hybrid mobile applications.

Best Performance

To boost the performance of your project:

  • Always use an up-to-date browser version.
  • Check Disable Script Debugging from your browser configuration options.
  • Activate Caching in Internet Explorer.


  • As of the Telerik UI for ASP.NET MVC 2017 R1 release, Internet Explorer 8 is no longer supported.
  • Browsers in beta stage are not supported.
  • Zoomed-in pages are not supported.
  • Zoomed-out pages are not supported. Different browsers handle sub-pixel calculations differently and zooming out the page may lead to unexpected behavior—for example, missing borders.
  • Exporting a zoomed-in or zoomed-out page to PDF is not supported.
  • Quirks mode is not supported.

    Always specify a DOCTYPE. Recommended DOCTYPEs include HTML5, XHTML 1.1, XHTML 1.0 Strict and HTML4 Strict. The HTML4 Transitional DOCTYPE fires the Quirks mode and should not be used. XHTML 1.0 Transitional works well in most cases, but may cause issues with the vertical positioning of icons. The correct syntax for all DOCTYPEs is provided on the W3C website.

  • Internet Explorer compatibility modes are not supported. These modes can exhibit different behavior and rendering bugs as compared to the browser versions they emulate.

  • It is highly advisable to use Internet Explorer Edge mode over a META tag or an HTTP header:

    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
  • Telerik UI for ASP.NET MVC uses a progressive enhancement for its CSS styling. As a result, old and obsolete browsers may ignore CSS 3 styles such as rounded corners and linear gradients.
