Following Microsoft's announcement about Internet Explorer (IE) being officially retired and out of support, the Telerik UI for ASP.NET Core 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 Core R1 2023.
The Telerik UI for ASP.NET Core 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.
Most Telerik UI for ASP.NET Core 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|
The Telerik UI for ASP.NET Core 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
BROWSER SUPPORTED VERSIONS 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
BROWSER SUPPORTED VERSIONS LIMITATIONS 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
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.
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 Core 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
XHTML 1.0 Strictand
HTML4 Strict. The
HTML4 TransitionalDOCTYPE fires the Quirks mode and should not be used.
XHTML 1.0 Transitionalworks 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 Core 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.
